Re: [OpenLayers-Users] 'undefined' at vertices while editingvectorlayer
Hi,
The features have no values = undefined, but a status of undefined. So
your comparison can not work.
The only idea I have, is to set i.e an attribute show=yes for features,
that should be labeled. And add the below rule:
var PolygonSymbolizer = { fillColor: ${color},
fillOpacity: 0.5,
strokeColor: ${color},
strokeOpacity: 0.8,
strokeWidth: 4,
pointRadius: 6
};
var TextSymbolizer = { label: ${name},
fontColor: #00,
fontSize: 24px,
fontFamily: Courier New, monospace,
fontWeight: bold
};
var Symbolizer = { Polygon : PolygonSymbolizer, Text : TextSymbolizer};
var rules = [ new OpenLayers.Rule({
filter: new OpenLayers.Filter.Comparison({
type: OpenLayers.Filter.Comparison.EQUAL_TO,
property: show,
value: yes,
}),
symbolizer: Symbolizer,
elseFilter: false
}),
new OpenLayers.Rule({
symbolizer: {Text:{
label:
}},
elseFilter: true
})
];
_aktLayer.styleMap.styles[default].addRules(rules);
_aktLayer.redraw();
The other way are to patch OpenLayers.Control.ModifyFeature.collectVertices
(row 634), that an other style will used for the vertices instead of the
default style.
Original line : vertex = new OpenLayers.Feature.Vector(component);
Patched line : vertex = new OpenLayers.Feature.Vector(component, null,
OpenLayers.Feature.Vector.style['select']);
But I'm not sure, if there are other and better ways to accomplish the task.

Betreff: Re: [OpenLayers-Users] 'undefined' at vertices while
editingvectorlayer
Thanks for the help. I see that the 'default' style is being used to render
the vertices, but I still don't understand how to prevent 'undefined' labels
from being applied to them.
I did look at the code for
OpenLayers.Control.ModifyFeature.collectVertices, but I'm not sure what to
do with it. It doesn't appear that styling is applied at this point, except
in the case of virtual vertices (which have the control's virtualStyle
applied). Could you explain a little more what you mean here?
I've also been trying to apply a rule like this:
new OpenLayers.Rule({
filter: new OpenLayers.Filter.Comparison({
type: OpenLayers.Filter.Comparison.EQUAL_TO,
property: name,
value: undefined,
}),
symbolizer: {
label:
}
});
What do you think of this approach? It seems like this might solve my
problem, but I'm having some difficulties getting it applied properly.
thanks,
alex

OpenLayers use the default style for rendering the vertices and in

undefined, then the renderer would use black to render the features,
but doesn't display a text message.
If you want to change this behaviour, then look at the function

As you can see in the screenshots, the 'color' attribute (eg $

when I'm not editing the feature. The 'undefined' text only appears when I
edit the feature using an instance of OpenLayers.Control.ModifyFeature.

Re: [OpenLayers-Users] Why is my WFS layer not showing up?
Hi, First: the point in the snippet you have posted, lies if the projection is right, south-east of Mallorca. If you take the projection EPSG:23031, then it should be in Barcelona. Second: When I use your wfs server with EPSG:23031, then the points will display in Barcelona. But only for the layer cloud2. The gml for the layers named by numbers are not valid. ms:4 seems to be no correct tag. You can test this by saving the response from firebug as xml and then you should be able by doubleclick to load it in your Internet browser. It will raise an error.

Re: [OpenLayers-Users] Looping through the features of a WMS layer
Hi,
if you use WMS you have no access to any features. You get only a picture.
For a certain point you can request GetFeatureInfo. If you want features,
you have to use WFS.
But keep in mind. You get only that from the servers, what they want to
publish (i.e attributes of GetFeatureInfo).

Re: [OpenLayers-Users] OpenLayers.Filter.Comparison.LIKE and singleChar
Hi Eric,
thanks for the reply and the hint. It's a more complex situation.
It's not a problem with the filter, but with OpenLayers.Format.SLD().read:
I create a SLD and apply it to a vector layer
var formatSLD = new OpenLayers.Format.SLD();
var sld = formatSLD.read(theSLD_BODY);
...
It works perfect, but only the LIKE-filter with . works not.
The filterpart from theSLD_BODY for this case looks like
ogc:Filter xmlns:ogc=http://www.opengis.net/ogc;
ogc:PropertyIsLike wildCard=* singleChar=. escape=!
ogc:PropertyNameindice/ogc:PropertyName
ogc:Literal.2/ogc:Literal
/ogc:PropertyIsLike
/ogc:Filter
The .2 enters the function OpenLayers.Filter.Comparison.value2regex
as 0.2 as number (typeof this.value - number ?!)
and causes the error this.value.replace is not a function.
if I overwrite the function by adding this.value=this.value.toString(), then
the error vanishes, but the applied rule to the vector layer doesn't result
in a correct style.
Appling the same SLD to the WMS layer, shows the correct style. It seems,
the SLD is correct.
I remember a case with labels like 02.09, that change to 2.09. Perhaps the
same issue.
If you have any hint, where to further look?
The little testcode from you was a great help for me to get to the right
error.
And this is still the same:
Also I don't understand, why '*2' finds items like 21, 23, 24.
What would you expect? From the Filter Encoding specs: The wildCard
character matches zero or more characters.
I would expect '2' or 'adadas2', but not '2klkölk'
Many thanks

The Comparision filter 'like' seems not to work as expected.

It looks good to me.
It causes an error 'this.value.replace is not a function'. It works

Hi, As I understand, the patch solves the problem, that the SLD will be created. Therefor I can use it for request WFS GetFeature.

The filterpart from theSLD_BODY for this case looks like ogc:Filter xmlns:ogc=http://www.opengis.net/ogc; ogc:PropertyIsLike wildCard=* singleChar=. escape=! ogc:PropertyNameindice/ogc:PropertyName ogc:Literal.2/ogc:Literal /ogc:PropertyIsLike /ogc:Filter The .2 enters the function OpenLayers.Filter.Comparison.value2regex as 0.2 as number (typeof this.value - number ?!) and causes the error this.value.replace is not a function. if I overwrite the function by adding this.value=this.value.toString(), then the error vanishes, but the applied rule to the vector layer doesn't result in a correct style. Appling the same SLD to the WMS layer, shows the correct style. It seems, the SLD is correct. I remember a case with labels like 02.09, that change to 2.09. Perhaps the same issue. If you have any hint, where to further look?

Re: [OpenLayers-Users] OpenLayers.Filter.Comparison.LIKE and singleChar
Hi Ian, Andreas
Ian's suggestion is an excellent one though, at least if you can control
how the SLD that OpenLayers
consumes looks.
I have thought, I could control it with OpenLayers.
I take
function createFilterComparision(type, theField, theValue)
{
var filter = new OpenLayers.Filter.Comparison({
type: type,
property: theField,
value: theValue
});
filter.value2regex(%, _); //translation back to '*' and '.'
return(filter);
}
to use other values for the wildCard and singleChar, in hope they get in the
SLD. But OpenLayers translate them back to '*' an '.'.
The SLD I create with OpenLayers hold '*' and '.' and reading this SLD to
style my features ends up with the issue, that '.' fails.
If i change manuel the singleChar in the created SLD and apply it to the
layer, then OpenLayers interprets it correctly.
But that's not what I want.
Nevertheless the Format.SLD and Filter is great.
Arnd

Betreff: [OpenLayers-Users] Untiled WMS on top of Google Maps doesn't
alwaysshow up
Dear all,
I'm trying to show an untiled WMS layer on top of a Google Map in
OpenLayers, but under certain conditions (esp. zoomlevel 2) the overlay is
not displayed. I have this problem with our own WMS layers but also with the
default MetaCarta WMS layer, both in Firefox 3.6 and IE8, using Openlayers
2.9.1.
The code below (init function is called on page load) will load Google Maps
as the base layer and overlay it with the default MetaCarta WMS as an
untiled WMS layer. The WMS layer is set to display by default but it is not
shown in the browser in the default extent. When you zoom in it does show
up.
Note that this only applies to untiled WMS, for tiled WMS (singleTile =
false) it works fine. Also note that the WMS layer is actually loaded
correctly (as can be shown by e.g. Firebug), it just isn't displayed for
some reason.
I'd be grateful for any hints or suggestions to solve this problem!
Kind regards,
Arjen.

Re: [OpenLayers-Users] externalGraphic anchoring points?
I have always thought the anchorpoint is left-top. But your nice example suggest it's the center of the externalGraphic. Looking at the code, it seems to be a bit complexer. SVG.js, similiar for VML.js var xOffset = (style.graphicXOffset != undefined) ? style.graphicXOffset : -(0.5 * width); var yOffset = (style.graphicYOffset != undefined) ? style.graphicYOffset : -(0.5 * height); If you declare the properties graphicXOffset and graphicYOffset in your style, then these values are taken for drawing. If you omit these properties, then an offset of half the width or height are taken. Because I use always the properties graphicXOffset=0 and graphicYOffset=0 in conjunction with externalGraphic, I have the anchorpoint always at left-top. If you want to use an offset to move the image, then you have to calculate from left-top and not from the center as your example seems to show.

So maybe an option named projectionalias would be a better name than sphericalmercatoralias or projection? projectionalias stresses the fact that the projection itself should not be different, just the code that is being used for the projection.

Re: [OpenLayers-Users] SphericalMercator and SRS aliases epsg:900913, epsg:3857, epsg:3785, epsg:102113
Hi,
I wouldn't restrict it to sphericalmercatoralias. I use a similiar approach
to add WMS Server, which use a different EPSG code than my map, but describe
the same projection.
Why not use options.projection to request the WMS in this projection?
OpenLayers.Layer.WMS.prototype.getFullRequestString =
function(newParams,altUrl)
{
try{
var projectionCode = typeof this.options.projection == 'undefined' ?
this.map.getProjection() : this.options.projection;
}catch(err){
var projectionCode=this.map.getProjection();
}
var value = (projectionCode == none) ? null : projectionCode
if (parseFloat(this.params.VERSION) = 1.3) {
this.params.CRS = value;
} else {
this.params.SRS = value;
}
return OpenLayers.Layer.Grid.prototype.getFullRequestString.apply(this,
arguments);
},

Hmm,
I didn't test my code properly, (layers without option sphericalmercator
stopped working). The following code should do better (Version = 1.3 not
yet tested):
// override OpenLayers.WMS.getFullRequestString class member function
OpenLayers.Layer.WMS.prototype.getFullRequestString = function(newParams,
altUrl) {
var projectionCode = this.map.getProjection();
var value = (projectionCode == none) ? null : projectionCode
if (this.options.sphericalmercatoralias)
{
if(value == 'EPSG:900913' || value == 'EPSG:102113' || value
==
'EPSG:3857') {
value = this.options.sphericalmercatoralias;
}
}
if (parseFloat(this.params.VERSION) = 1.3) {
this.params.CRS = value;
} else {
this.params.SRS = value;
}
return
OpenLayers.Layer.Grid.prototype.getFullRequestString.apply(this,
arguments);
}
After this override, you can set a new layeroption 'sphericalmercatoralias'
to tell OpenLayers to use that instead of the default as follows:
layer = new OpenLayers.Layer.WMS(title, url, {layers: layernames},
{sphericalmercatoralias: EPSG:102113});

Hi,
OpenLayers have no possibilties to get the extent from the WMS.
You can try to get the extent
by WMS GetFeatureInfo (if you have a point, that indicates the state) or
by WFS using the stateId for filter the WFS GetFeature.
and then
map.zoomToExtent(Bounds);

Betreff: [OpenLayers-Users] Zoom to dinamic WMS Layer
Hi people, how are you doing?
I'm having troubles to find the way to zoom to a polygon WMS layer that is
dinamically filtered..
Let's put this on an example:
You have the USA states map and you have an ID for each state; you define
your WMS layer to something like this:
var stateID = funcToGetFromURLParam(stateID);
states = new OpenLayers.Layer.WMS(
States, http://server:8080/geoserver/wms;,
{
transparent: 'true',
layers: 'Workspace:states',
srs: 'EPSG:4326',
format: 'image/png',
filter:
FilterPropertyIsEqualToPropertyNameID/PropertyNameLiteral+stateI
D+/Literal/PropertyIsEqualTo/Filter
});
map.addLayer(states);
How would you zoom to this layer (to it's maximum extension, to it's
bounderies.. got what I tried to say?) after is filtered and loaded? I tried
in so many ways but I could not. :S
Thanks for your time folks!
Best regards,
Gilberto Ramos

Betreff: [OpenLayers-Users] Trying to troubleshoot a map: redrawing
layerwith SLD style
Hi, everyone,
I posted just the other day about a map that I'm building. The idea has
been changed to a simpler one. Through a form, the user constructs a
variable that represents the attribute to be considered, then a style is
built and attached to the layer in question and the layer is redrawn. It
should be fairly simple, but my newness to JS and OpenLayers is getting in
the way.
I seem to have all kinds of problems with this map,1) For some reason,
battlegroundData is rendering as a base layer, not an overlay, 2) I think
that something is wrong with the projection and 3) I'm not sure whether I
read the documentation correctly for writing the style SLD and then
attaching it.
Mind helping a brother meet his deadline?

Re: [OpenLayers-Users] Proportional Symbols from GMLattributes/OpenLayers
Hi,
Use for your gml layer the option extractAttributes: true to get features
with attributes.
Use a styleMap for your layer, where your pointRadius is set by an attribute
:
var template = {
strokeColor: #FF,
...
pointRadius: ${yourAttribute}
};
styleMapRotation = new OpenLayers.StyleMap(new OpenLayers.Style(template));
or you use a styleMap with context, if you want calculate the radius by
other conditions :
function set_styleMapRotation()
{
var context = {
getPointRadius : function(ft){
var zoomOffset = map.projection == EPSG:4326 ? 1 : 8;
var fktr=1;
var diffZ = map.getZoom() - zoomOffset;
return diffZ 0 ? 7 + 3*diffZ*fktr : 8;
}
};
var template = {
strokeColor: #FF,
...
pointRadius: ${getPointRadius}
};
styleMapRotation = new OpenLayers.StyleMap(new
OpenLayers.Style(template, {context:context}) );
}
set_styleMapRotation();
Example with pointRadius set by the attribute for the population of cities
and label size by zoomLevel

Re: [OpenLayers-Users] Zoom to point given feature ID by GET
Hi,
Below some code to get the idea
//http://yourServer/someSide/page.html?CENTER=100,120ZOOM=8
function init()
{
var CENTER = [2627000, 5685625];
var ZOOM = 0;
objParams = OpenLayers.Util.getParameters();
var CENTER = objParams.CENTER ? objParams.CENTER.split(,) : CENTER;
var ZOOM = objParams.ZOOM ? parseInt(objParams.ZOOM) : ZOOM;
var theID = objParams.ID ? objParams.ID : null;
...
...
map.setCenter(new OpenLayers.LonLat(CENTER[0], CENTER[1]), ZOOM);
if(theID != null)
{ vectorLayer.events.register(loadend, vectorLayer, function (e) {
var objFs = this.features;
for(var i=0;iobjFs.length;i++)
{ if(objFs[i].ID = theID;
{ var objBounds = objFs[i].geometry.getBounds();
var x = (objBounds.left+objBounds.right )/2;
var y = (objBounds.top +objBounds.bottom)/2;
CENTER = [x, y];
break;
}
}
});
map.setCenter(new OpenLayers.LonLat(CENTER[0], CENTER[1]), ZOOM);
}
}
To center your map by a feature of a vector layer you have to be sure, that
your features are loaded.
I would center my map to default values, register a loadend for the vector
layer, and then would parse for the feature by id and then set the center by
the new value.

that's how I would do it. Use an Ajax request to get the GML-file and then
parse it and add every feature to an new vector layer.
If your GML-file residents on the same server (use relative path to the
gml), then you don't need a proxy script.
If have tested the below code locally with the example
spherical-mercator.html.
var formats = {
wkt: new OpenLayers.Format.WKT(),
geojson: new OpenLayers.Format.GeoJSON(),
georss: new OpenLayers.Format.GeoRSS(),
gml: new OpenLayers.Format.GML(),
kml: new OpenLayers.Format.KML()
};
function getGML()
{
theUrl = /OLClient/some.gml;
var myAjax = new OpenLayers.Ajax.Request(
theUrl,
{
method: 'get',
onComplete: showResponse,
onFailure: showResponseFailure
});
}
var arr = [];
function showResponse(response)
{
var theParser = formats[gml];
theParser.internalProjection = null;
theParser.externalProjection = null;
theParser.extractStyles = false;
theParser.extractAttributes = true;
var features = theParser.read(response.responseText);
if(features)
{
if(features.constructor != Array)
features = [features];
//iterate the features and put them on a vector layer
for(var i=0;ifeatures.length;i++)
{
//get the feature type
var ftType =
features[i].geometry.CLASS_NAME.replace(/OpenLayers.Geometry./,);
//count the feature of a type
arr[ftType] = arr[ftType] + 1;
var ftLyr = new OpenLayers.Layer.Vector(ftType + +
arr[ftType]);
map.addLayer(ftLyr);
ftLyr.addFeatures(features[i]);
}
//to zoom to the features
var bounds = features[0].geometry.getBounds().clone();
for(var i=1;ifeatures.length;i++)
bounds.extend(features[i].geometry.getBounds());

Hi
The protocol or format that you use will give you an array of
features. You are then free to dispatch the features to separate
vector layers, for example based on their ids.
I hope it helps,

don't you have some calls to throw in your code to make it easier to
debug...
Thanks in advance

Re: [OpenLayers-Users] WFS Not Returning Coordinates
Hi Roald,
Adding propertyNames (attributes of the feature) to the protocol solves the
problem with the geometry for MapServer 5.6.1. First I thought it wouldn't
work, because i added msgeometry instead of msGeometry. And I have to add
srsName to the protocol, what for version 5.2 is not needed.
thx
Arnd

Betreff: Re: [OpenLayers-Users] WFS Not Returning Coordinates
Hi Blake,
You can work around this issue by providing the property names explicitly in
the options of your protocol, including the name of the geometry.
Example:
propertyNames:
'year,seq,name,storm_start,storm_end,msGeometry'.split(',')
Note that MapServer by default chooses 'msGeometry' as the name of the
geometry attribute even though it might be called 'the_geom' or
'wkb_geometry' on the data source. In your case it's 'location' I presume.

Betreff: [OpenLayers-Users] WFS Not Returning Coordinates
Hello,
I'm using WFS Protocol on a vector layer (as per the example) to plot
data on the map from a wfs server:
var geographic = new OpenLayers.Projection(EPSG:4326);
var layer = new OpenLayers.Layer.Vector(WFS, {
strategies: [new OpenLayers.Strategy.BBOX()],
protocol: new OpenLayers.Protocol.WFS({
url: http://mapserver.worldflightplanner.com/radar/;,
featureType: flightrules,
featureNS: http://mapserver.gis.umn.edu/mapserver;,
featurePrefix: ms,
version: 1.1.0,
geometryName: location,
srsName: EPSG:4326,
extractAttribute: true
}),projection: geographic
});
This works fine, however, the returned GML from the WFS does not
contain any coordinates, just the metadata. Is this something wrong
with my Mapserver configuration, or my OL call?
You can see the request, and the returned data here:
http://pastebin.org/284683

Re: [OpenLayers-Users] GetFeatureInfo returns attribute nameonly(Mapserver Openlayers)
Hi,
It's an issue with MapServer. If the returned html shows only [NAME] as in
the template, then it means, that MapServer couldn't resolve the tag.
Perhaps you have no column NAME in your data or it's an issue with upper and
lowercase.
Try
'wms_feature_info_mime_type' 'text/plain'
'wms_include_items' 'all'
To get the result with all attributes, that are availible.

Can anyone show me an example of how to get the layers in a openlayers
wms.layer?
Here's an example:
cities = new OpenLayers.Layer.WMS(US Cities, wms_path,
{layers: 'Public:US_Cities'} );
I'm able to read items like the layer name (which would be US Cities
in the above example, with:
layer.get(layer).name
but haven't had luck with getting the layers listed in the paramaters (
{ layers: })
I want to know how to get the value 'Public:US_Cities'

Re: [OpenLayers-Users] kml-files doesn't shown correct
Hi,
It seems to be a projection error. Your data come in EPSG:4326 (-180 - 180,
-90 - 90), that's in sphericalMercator equal 0,0 near Africa.
I would think, that you use map.projection sphericalMercator and for
map.displayProjection also sphericalMercator.
Set in the layer declaration projection: EPSG:4326 and your data should be
at the right place.

Then I see only one icon in the sea nearby Africa and not in Germany. :-(
But the result should looks like that:

I try some other kml files and it works.
Could it be that this kml file is incorrect?

Re: [OpenLayers-Users] HELP!!! How implement Filter in WMS Layer
Hi Paul,
SLD_BODY is a request parameter of a wms. If you can get from your grid a
reference to your OpenLayers WMS layer, then you can use
yourWMSlayer.mergeNewParams('SLD_BODY' : ).
if your wms have only one layer (in the eample below POLYGONS) to request,
you can use something like this
StyledLayerDescriptor version=1.0.0 xmlns=http://www.opengis.net/sld;
xmlns:gml=http://www.opengis.net/gml;
xmlns:ogc=http://www.opengis.net/ogc;

/StyledLayerDescriptor
as SLD_BODY to highlight the the features of the layer. Attention! You have
to delete the line feeds for the request.
Zooming to the extent of the wms layer is not so easy, perhaps inpossible.
You can request the WMS GetCapabilities and hope that there the correct
extent are described for the layer. Or if the layer is also requestable as
WFS you can perhaps on that way get the extent of the layer. But I'm not
sure.
If you are the holder of the WMS server, I would suggest, that you calculate
the extent on other ways and adds it as array to your application.

Betreff: Re: [OpenLayers-Users] HELP!!! How implement Filter in WMS Layer
Hi Arnd...
I have some questions about that...
First I have a geo app using Openlayers/Mapserver WMS with SDE layers
My application has a treeview with all layers, and a radiobox for each
layer... When I click in a layer´s radiobox a window with a GRID containing
all layer´s data is opened...
In that GRID, When I select a line (layer´s data), the Map should :
1-) Highlight it
2-) Zoom in data selected
Can I develope that using SLD and SLD_BODY ? Do you have any tip to how do
that?
Thanks

Hi,
You can do it on runtime with

I use this way to highlight a choosen country

Betreff: [OpenLayers-Users] show only specific objects, wms
Hy all,
I use GeoServer with OpenLayers.
I have a WMS Layer with many kinds types of objects. How can I show only for
example object whose attribut has a special value?
I know I can create SLD so that it shows what I need. But the problem ist
that I have about 1000 different attribut values. And I can't create 1000
SLD documents...
I hope you understood my problem...
Is this possible with a WMS Layer?
Or is there a way I can change the SLD on runtime?
cheers David

map = new OpenLayers.Map(map, options);

Re: [OpenLayers-Users] unselect did not work
Hi Sarah,
the example shows how to retrieve features from a wms layer. But you have a
vector layer (wfs layer). So you can link the SelectFeatureControl to that
layer.
ctrlSelectFeatureOptions = { clickout: true, toggle: true, multiple: false,
hover: false, toggleKey: ctrlKey, multipleKey: none, box: false };
ctrlSelectFeature = new OpenLayers.Control.SelectFeature(layerWFS,
ctrlSelectFeatureOptions);
//optional
ctrlSelectFeature.onSelect= function (ft) { };
ctrlSelectFeature.onUnselect = function (ft) { };
ctrlSelectFeature.activate();
If you now click on a feature from your wfs it will be selected. If you do
not add a own styleMap to your wfs layer, the default styleMap is used to
display the features for the different modes (unselected, selected or
temporarily).
If you want use your own styleMap, you have to declare the styles for the
different modes (at last 'default' for unselected features and 'select' for
selected features) to see that you have select a feature.

Betreff: AW: [OpenLayers-Users] unselect did not work
Hi Arnd,
thanks for your answer!
Please read below.

Hi,
i'm not sure, why you need a layer for your selected feature. Why not use
the selectFeatureControl on the wfs layer.
I use my Control.SelectFeature with my wfs layer(wfs2)- or don`t I use the
event right? (event.register instead of events.on). I get along with this
example:
http://dev.openlayers.org/releases/OpenLayers-2.9/examples/getfeature-wfs.ht
ml to get back a visual selecting for the user and get back some information
about the selected feature.
About your question.
The problem is the feature object. You add not a new feature to a new layer.
Instead it seems, that you move the selected feature from the wfs layer to
the new layer. That means wfs.event.on(unselected) cann't work, because
your selectFeatureControl works only for the wfs layer.
Yes I thought something like that, but could not manage to solve this.
Thanks for your example!
Use a clone of the feature and remove the only feature on your select layer.
layerWFS.events.on({'featureselected': function(feature){
selectLayer.addFeatures([feature.feature.clone()]);
//selectLayer.addFeatures([feature.feature]);
alert(this.selectedFeatures.length);
},
'featureunselected': function(feature){
selectLayer.removeFeatures([selectLayer.features[0]]);
//selectLayer.removeFeatures([feature.feature]);
alert(this.selectedFeatures.length + -
unselected);
},
});
A bit confusing is also the style you add as default style to the select
layer. It looks like you select a feature on the wfs layer, but it's really
the not selected feature on the select layer.
So I have to register a select style to my wfs layer and cancel select
layer, am I right?
best regards
Sarah

Re: [OpenLayers-Users] Simple vector problem
Hi,
var map = new OpenLayers.Map('map');
without declare any map options, means, that OpenLayers takes the default
for the map options. That means EPSG:4326 with maxExtent = [-180, -90, 180,
90].
As your data is in an other projection, OpenLayers tries to reproject the
vector data. But I think, you don't use the proj4js library, so OpenLayers
fails to reproject the data. And the unprojected data do not fall into
maxExtent for EPSG:4326;
Try something like this:
map = new OpenLayers.Map('map',
{ maxExtent: new OpenLayers.Bounds(31789.1658, 790194.4183,
337250.8970, 961865.1338), //from

Re: [OpenLayers-Users] Place Point at x% y% to an no geographicLayer.TileCache possible?
Hi,
i cann't help you with your problem, but perhaps the below gives you some
idea how to resolve it.
In OL a map has always a projection. If you not declare a projection, then
OL choose by default EPSG:4326 with maxExtent [-180, -90, 180, 90].
In your case you want only a mathematical xy plane. I use in this case
EPSG:900913 as projection for the map. So I have a large xy plane to work
on.
map = new OpenLayers.Map('map',
{ maxExtent: new
OpenLayers.Bounds(-20037508.34,-20037508.34,20037508.34,20037508.34),
numZoomLevels: 22,
//maxResolution: 156543.0399,
maxResolution: 20.0,
units: 'm',
projection: new OpenLayers.Projection(EPSG:900913),
theme : theme/default/style.css,
controls:[]
});
The above map options are from
http://gis.ibbeck.de/ginfo/apps/pentominoes/pentominoes.html.
As you can see, this has nothing to do with projection. Nevertheless you
have one to choose, when you use OL for your project.

attributes.
It works fine, except that it looks lousy when I zoom out. The labels are
still drawn the same, even though the features may be nearly invisible.
How do I turn off the rendering of labels, when the scale exceeds some
threshold? (Note - I still want to draw the features, I simply don't want
the labels.)
I've tried adding a listener to map.movestart, that changes the value of
layer.styleMap.styles['default'.defaultStyle.label, but that only affects
future renderings of the map, it has no effect on the current zoom.

solution:
Overwite of
OpenLayers.Handler.RegularPolygon.prototype.createGeometry = function()
{
this.angle = Math.PI * ((1/this.sides) - (1/2));
if(this.snapAngle) {
this.angle += this.snapAngle * (Math.PI / 180);
}
this.feature.geometry =
OpenLayers.Geometry.Polygon.createRegularPolygon(
this.origin, this.radius, this.sides, this.snapAngle
);
/* doesn't work. wahrscheinlich wird nur die Geometrie zurückgegeben und
das Feature daraus erstellt.
this.feature.origin = this.origin;
this.feature.radius = this.radius;

this.feature.geometry.origin = this.origin;
this.feature.geometry.radius = this.radius;
//console.log(create: + this.origin + , radius: + this.radius);
};
OpenLayers.Handler.RegularPolygon.prototype.modifyGeometry = function()
{
//console.log(modify: + this.origin + , radius: + this.radius);
var angle, dx, dy, point;
var ring = this.feature.geometry.components[0];
// if the number of sides ever changes, create a new geometry

Betreff: [OpenLayers-Users] How to get position of feature from DrawFeature?
I am using the Draw Feature Control to draw polygons (namely circles) on a
Vector Layer. I want to be able to save the center of the circle to a
variable, as well as the radius of the circle.
I'm not seeing any native way to do this. When I draw a feature, I'm
assuming it's a Vector Feature, which has geometry and attributes. When
I look at the geometry, I get a bunch of points (I'm assuming 40, since
that's how many sides I told my polygon to have).
My choices are to figure out some complicated way to turn that array of
points into a center and a radius, or (my preference) to manually save the
position the mouse is clicked down, and the position the mouse is let up
(down is center, the distance from up and down is the radius). However, I'm
having difficulties doing that as well: There doesn't seem to be any way to
get a mousedown even from a Vector Layer? At least, I'm not seeing any
response when I do things like:
polygonLayer.events.register(mousedown, feature,
function(evt){
console.log(Mouse Down);
});
Which implies to me that Vector Layer doesn't inherit from anythign with a
mouse down?
Doing :
document.captureEvents(Event.MOUSEDOWN);
document.onmousedown=function(event) {
alert(event.type) // mousedown
}
works fine...everywhere but my map and layer...which doesn't help me much,
and (I'm unfamiliar with javascript still),
polygonLayer.captureEvents(Event.MOUSEDOWN) doesn't work either (firebug
says the function captureEvents doesn't exist for VectorLayer.
I must be missing something obvious due to my inexperience: How can I find
out where a user's mouse is when the click down, then let up?

p.s. (Still haven't figured out my polygon refresh issue)

Re: [OpenLayers-Users] VectorLayer destroyFeatures doesn't workproperly?
Hi,
It seems, that 'beforefeatureadded' not works as one would expect.
I would think, that the feature is already in the layers features array, but
still drawn on a temporary layer. Deleting the feature(s) works, but obvious
do not clear the temporary layer.
function clearCircles(){
console.log(Clearing existing circles);
console.log(polygonLayer.features.length);
polygonLayer.destroyFeatures(polygonLayer.features);
polygonLayer.redraw();
}//end clearCircles
You have to control, if there are more then one feature in the layer array.
Then you can delete the first.
polygonLayer.events.register(beforefeatureadded, polygonLayer,
function(evt){
if(polygonLayer.features.length1)
{
console.log(B: + polygonLayer.features.length);
polygonLayer.removeFeatures(polygonLayer.features[0]);
console.log(--Clearing existing circles--);
console.log(C: + polygonLayer.features.length);
}
console.log(A: + polygonLayer.features.length);
});//end attempt at events registration
As an better solution I would suggest to delete the previous feature, when
the drawing starts.
polygonLayer.events.on({
sketchstarted: function(evt)
{ if(polygonLayer.features[0])
polygonLayer.removeFeatures(polygonLayer.features[0]);
}
});

Re: [OpenLayers-Users] Just another trasformation problem ;)
Hi beppe,
the projection parameter is at the wrong place. That is the correct place:
var isoline = new OpenLayers.Layer.Vector(isoline, {
strategies: [new OpenLayers.Strategy.Fixed()],
projection: epsg2498,
protocol: new OpenLayers.Protocol.HTTP({
url: isoipse_2498.gml,
format: new OpenLayers.Format.GML()
})
});
and delete the line
isoline = OpenLayers.Projection.transform(isoline, epsg2498,
map.projection);
that have no effect.
you have write correctly a gml layer, but overseen as I, that the projection
belongs not to the protocol.
I have created a little example to show the projection on the fly with
proj4js
http://gis.ibbeck.de/OLClient/examples/armenia_900913.html
The gml is in projection EPSG:2498 and map.projection is EPSG:900913.
2.
if you want to edit vectors with OpenLayers and then save them, you have to
use WFS-T (with GeoServer, FeatureServer). Or as a simple solution you can
use a serverside script to save your vectors as gml (kml, ...) to your local
drive. Only with strategy save it works not.

Betreff: Re: [OpenLayers-Users] Just another trasformation problem ;)
Thanks for suggestion but doesn't works yet!!!
I found a solution using qgis plugin ogr2layer, maybe the problem was in
the parameters used in transformation code:
# isoline = OpenLayers.Projection.transform(isoline, epsg2498,
map.projection);
new code is:
# map.addLayer(new OpenLayers.Layer.GML(isoipse_2498
GML,../aramus_data/vector/reproj/isoipse_2498.gml));
# var extent = new
OpenLayers.Bounds(4970294.552162,4901870.266154,4971024.689123,4902439.54224
4).transform(new #OpenLayers.Projection(EPSG:2498), new
OpenLayers.Projection(EPSG:900913));
and now works!!!
Anyway, I would like understand how to write correctly a gml layer!
Another question for you:
the second step is to be able to modify the gml, is it possible with
strategy save?

Perhaps you do two times a transformation. I would think, that in your

needed.

Hi all,
I ought to display a map with osm layer as base and a gml file of a little
part of Armenia.
First step was convert my shapefile, with projection epsg:2498, in a gml
format (ogr2ogr -f GML ...).
Second step was set up my map.
Within tag head of my html page, I' ve insert a link to these libraries:
- OpenLayers-2.8/OpenLayers.js
- http://www.openstreetmap.org/openlayers/OpenStreetMap.js
- proj4js.js
- proj4s/lib/defs/EPSG2498.js
And this is a snippet of my map code [1].
The problem is that my gml is in the north of Africa instead of Armenia.
I've tried with qgis and the layer is correctly positioned, so I suppose
that the problem is in the code, but I' m not able to detect the bug!!!
thanks

Re: [OpenLayers-Users] please help us test OpenLayers 2.9RC1
Hi,
Because in previous versions of OpenLayers the map options parameters center
and zoom had not have an effect by the map construction, I have used them to
store values, which I use after adding the layers to the map.
I think now, it's bad programming to store own values in the options for a
contructor.
And I like the possibility in 2.9 to build a whole map only with the map
construction.

Hi Arnd,

http://trac.openlayers.org/changeset/10044
Tim, are you able to comment on Arnd's suggestion (see below)? TIA.
http://trac.openlayers.org/ticket/2561
Calling setCenter before adding layers has always failed. I considered it
equivalent behavior to require layers in the constructor if a center was
provided (and included a test to enforce this).
Arnd, while things might be working for you at 2.8, I'd consider it somewhat
risky to set map center (and zoom) in the options and then call setCenter
again with the same values after adding layers. There are a number of
checks that compare the current center/zoom to the values passed to
setCenter. If things haven't changed, I think it is reasonable to assume
that setCenter should do nothing.
Not sure what others think, but I can imagine that at some point we'd forget
this case and make it so setCenter had no effect if the passed values were
already set on the map.
Actually, it would probably be better to do whatever needs to be done in
setCenter without failing when there are no layers.
Anyway, the ticket is up for review.
Tim

Hi Bart,
I use the center parameter of the map options to store the center of
my map.
After adding my layers to the map I use map.setCenter with this
coordinate.
With the OpenLayers 2.9 RC1 library, this raise an error maxExtent
is null, because if center is set in the options, this.setCenter is
called at the end of the initialize-function. But then I have not
added any layer to the map.
It seems, that this will only work, if the layers parameter is also
set in the map options.
http://gis.ibbeck.de/OLClient/examples/testMapCenter_29_RC1.html
I would suggest, that the setCenter in the init function should only
be called, if this.options.layers != null.
// add any initial layers
if (options options.layers) {
this.addLayers(options.layers);
}
// set center (and optionally zoom)
if (options options.layers options.center) {
// zoom can be undefined here
this.setCenter(options.center, options.zoom);
}
And I have noticed, that with exchange of the OpenLayers.js from 2.8
to 2.9, also the style.css have to be taken fom 2.9 with the css for
the LayerSwitcher control.
Otherwise it seems, that 2.9 works like 2.8. A great job from the
OpenLayers developers.

fontFamily: Arial,
labelAlign: cb,
fillOpacity: 1,
pointRadius: 15
}),
...
and playing with labelAlign, but the label still passes through the image.
It would be really great if you could do something like:
labelOffset: new OpenLayers.Pixel(0,-10),
and have it shift the label position in Y by -10 pixels.
I looked through the code, but I'm not seeing a way to do that. Does anyone
else think this would be useful? Is there a patch for this by any chance?

Re: [OpenLayers-Users] Labels on WFS layers
Perhaps there is something wrong with the way you declare your style for
your layer.
The below code works on WFS layer. ADMIN_NAME is an attribute of the wfs.
var styleMapLabelDS;
function set_styleMapLabelDS()
{
var template = {
strokeColor: #FF,
strokeOpacity: 1,
strokeWidth: 3,
fillColor: #00AAFF,
fillOpacity: 1,
pointRadius: 5,
pointerEvents: visiblePainted,
label : ${ADMIN_NAME},
labelOffsetX: 10,
labelOffsetY: -10,
fontColor: red,
fontSize: 10,
fontFamily: Arial,
fontWeight: bold,
labelAlign: lt
};
var templateB = {
strokeColor: #FF00FF,
strokeOpacity: 1,
strokeWidth: 3,
fillColor: #AA00FF,
fillOpacity: 1,
pointRadius: 5,
pointerEvents: visiblePainted,
label : ${ADMIN_NAME},
labelOffsetX: 10,
labelOffsetY: -10,
fontColor: blue,
fontSize: 10,
fontFamily: Arial,

};
styleMapLabelDS = new OpenLayers.StyleMap( { default : new
OpenLayers.Style(template), select : new OpenLayers.Style(templateB) } );
}
set_styleMapLabelDS();
myWFS[styleMap]=styleMapLabelDS;
myWFS.redraw();

Betreff: Re: [OpenLayers-Users] Labels on WFS layers
Hello again,
I can't get this to work in any way, no errors at runtime but no labels
either. The label properties is listed in the vector style specification,
among other that work perfectly:
http://dev.openlayers.org/releases/OpenLayers-2.8/doc/apidocs/files/OpenLaye
rs/Feature/Vector-js.html
It can also be found a great deal of discussion on this list and elsewhere
about the development of this functionality, mostly from 2008. Has vector
labeling been fully implemented in OpenLayers-2.8? If not, what other ways
are there to get this to work?
Thank you,
Luís

Hello Robert,
I don't know ArcGis Server, but I would look, if you can get your data in

Re: [OpenLayers-Users] WMS from ArcGIS Server on top of google maps -Parameter 'srs' contains unacceptable value.
Hi Philipp,
the function OpenLayers.Layer.WMS.prototype.getFullRequestString have to be
load after the OpenLayers script(s) are loaded (the function overwrites the
original function from OpenLayers) and before the declaration of the Layer.WMS.
It should be something in this way:
...
script src=../lib/OpenLayers.js/script
script type=text/javascript
OpenLayers.Layer.WMS.prototype.getFullRequestString = function(newParams,altUrl)
{
try{
var projectionCode=typeof this.options.projection == 'undefined' ?
this.map.getProjection() : this.options.projection;
}catch(err){
var projectionCode=this.map.getProjection();
}
this.params.SRS = projectionCode==none ? null : projectionCode;
return
OpenLayers.Layer.Grid.prototype.getFullRequestString.apply(this,arguments);
}
function init()
{
var boundaries = new OpenLayers.Layer.WMS( Boundaries,
http://ag-0988a/ArcGIS/services/StateBoundaries_WGS84_WM_102113/MapServer/WMSServer?;,
//parameter

Hi Arnd,
thank you for the response, unfortunately I don't know where to use or replace
your code snippet in my .js file.
The WMS I work on has the following parameters.
var boundaries = new OpenLayers.Layer.WMS( Boundaries,
http://ag-0988a/ArcGIS/services/StateBoundaries_WGS84_WM_102113/MapServer/WMSServer?;,
{layers: '0',
//projection: 'EPSG:102113',

'image/png',
transparent: true
},{
visibility: true,
isBaseLayer: false,
singleTile: false }
);
I added the projection: 'EPSG:102113' but it didn't seem to change anything.
Where would go your code? Would it replace the the whole section of var
boundaries or would it be an additional part?
I'm a little lost.

How do I go from here, what are my options? I need to use Google as baselayer

2010/3/2 Alexandre Dube ad...@mapgears.com:
Olivier,
The way to defined your default symbolizer with the applyDefaults
method is correct, but you didn't do so with your select symbolizer.
In order for a point to be drawn, it needs more than these two
properties (like pointRadius for example). Try using applyDefaults there
too.
Then, remove the style from your point features too. In order for a
feature to change style automatically when selected, it has to be done
with the StyleMap or manually. If you set a symbolizer (style)
directly to your feature, that's the only style it's going to have
regardless of any stylemap defined.
// are you saying that with this, points don't show at all when unselected
?
Normally, it shouldn't.
var feature = new OpenLayers.Feature.Vector(point);
Kind regards,
Alexandre

I could make it work, but now I need to highlight these lines and points.
Actually I need to change the colour of either lines or points when
they are selected in a list outside the map or clicked on the map.
To do this, I added a SelectFeature control to the layer containing
the routes.
I could make it work for lines by adding the following style map to
the routes layer :
var symbolizer = OpenLayers.Util.applyDefaults(

}
, OpenLayers.Feature.Vector.style[default]);
var styles = new OpenLayers.StyleMap({

But I can't make it work with points.
I create the points this way :
var point = new OpenLayers.Geometry.Point(lon, lat, 0);
point.transform(map.displayProjection, map.projection); var styleSite
= OpenLayers.Util.extend({},
OpenLayers.Feature.Vector.style['default']);
styleSite.strokeColor = blue;
styleSite.fillColor = blue;
styleSite.pointRadius = 3;
styleSite.strokeLinecap = square;
var feature = new OpenLayers.Feature.Vector(point, null, styleSite);
The points display OK, but colour doesn't change when I select the point.
I think my problem deals with style, but I can't find what is wrong.
Note I had to set the style for point vector. If I don't do this, it
doesn't diplay. I find this strange since I don't need to do this for
line feature !
Any idea what I did wrong ?

Olivier

For what I understood, when you define a default style, other styles
extend this default style. So when defining a select style for example,
you just have to set the style attributes that you want to be different from
default style. And it works very well indeed. I read this there :
http://trac.openlayers.org/wiki/Styles#UsingPropertyStyles
Anyway, I just found where my problem comes from. Actually I use rules with
my style map, this way :
var lookupSens = {
aller: {strokeDashstyle: solid},
retour: {strokeDashstyle: dash}
};
styles.addUniqueValueRules(default, sens, lookupSens);
This rule helps me to have a different style for journey and return journey.
But since it has no sense for points (just for lines), I don't have the
sens property on the point I add to the layer, and it looks like it causes
some problems !
If I remove this rule, the points print OK. But I really need this rule, so
I can't remove it.
Do you know if there is a way to tell OpenLayers to apply the rule only for
some elements of the layer ? Or another workaround for this ?

Olivier

Re: [OpenLayers-Users] Beginner issue
Hi,
1. you have to reproject your vector data (with EPSG:900913 and EPSG:4326 it
is possible without proj4js)
2. you have to add your vector layer to your map
3. you have to center the map
//! set projections for transformation your vectors (before wkt_f.read)
wkt_f.internalProjection = new OpenLayers.Projection(EPSG:900913);
wkt_f.externalProjection = new OpenLayers.Projection(EPSG:4326);
//! add vector layer
index_map.addLayer(hood_vector);
//! set MouseDefaults for navigation
index_map.addControl(new OpenLayers.Control.MouseDefaults());
//! center map
index_map.setCenter(new OpenLayers.LonLat(lon, lat), zoom);
that should show your map.

Betreff: Re: [OpenLayers-Users] OL + database
It's always good to know what options are available, but in this case
GeoServer etc. definitely qualify as an unnecessary complication. OL is
sufficient for this job.
What I needed was this:
http://openlayers.org/dev/examples/vector-formats.html
and this:
http://www.w3schools.com/php/php_ajax_database.asp
I've trimmed the code from the vector-formats example down to just geojson.
That works nicely. The simple ajax script lets me interact with the database
as needed and it's quite easy to convert the geojson string into php
variables and vice versa.
The only thing I haven't figured out is how to access specific parts of the
geojson string within OL. Eg. if you copy this into the vector-formats
example above:
{type:Feature, id:OpenLayers.Feature.Vector_107,
properties:{icon:icon_1.jpg}, geometry:{type:Point,
coordinates:[26.015625, 18.6328125]}, crs:{type:OGC,
properties:{urn:urn:ogc:def:crs:OGC:1.3:CRS84}}}
You can see that everything gets pulled into OL by the script.
On my own page I can return the id and coordinates via feature.id and
feature.geometry.x /y, but so far have had no luck trying to access other
parts, eg. properties:{icon:icon_1.jpg}. Any geojson'ers know how to
get at these?

Re: [OpenLayers-Users] Trying to draw a box on a map, and get the coordinates back.
Hi,
function findcoords (event) {
var vertices = event.feature.geometry.getVertices();
var brackets =
vertices.toString().replace(/POINT\(/g,[).replace(/\),/g,],).replace(/
/g,,).replace(/\)/,]);
alert('ID:' + brackets);
}
This is one way to get what you want. If there is a simple way to get the
coordinates in this form from a geojson string or object, i don't know.

Thanks again Arnd.
I was able to get the coordinates back, however they are formatted
differently.
i get a csv list i.e. 50, 0, 50, 50, 0, 50, 0, 0, 50, 0 instead of brackets
i.e. [50, 0], [50, 50], [0, 50], [0, 0], [50, 0]
i am using the value to get the coordinates of a polygon added to my map so
i can save it to a database and dynamically create a json file for my
openlayers map, it looks like the only issue is the brackets, it crashes
without them and i cannot fiigure out how to get them.
should i save them to the database the way they are and try to add the
brackets in my php code when creating the json?

Re: [OpenLayers-Users] Maxextent, resolution and zoom issue
Hi,
that's from an OS OpenSpace map for the whole UK:
osMap.getMaxResolution() : 2500
osMap.getExtent() for zoomLevel 0 (whole UK) : left-bottom=(-611483,-135514)
right-top=(1888517,1364486)
osMap.resolutions : [2500,1000,500,200,100,50,25,10,5,2,1]
The example you refer to, seems to display only a small area of the UK,
perhaps Southampton.

Hi, i have been struggling with this problem for some time now.
Basically I am trying to display two layers. 50k and 250K of the uk. Can
anyone explain further what resolution, maxextent and zoom values I should
have to display these layers correctly? My layers cover the whole of the UK.
I have tried quite a few different values however I cannot make sense of how
this works. The example I am referring to is below.
Thanks for any help in advance
Create an options object that holds a limited set of map resolutions and a
maximum bounding extent to show the map. A new OS OpenSpace map object is
created by passing in our 'map' HTML div element id and the map options.
1. var options = {resolutions: [10, 5],
2.maxExtent: new OpenSpace.MapBounds(40, 10,
45, 15) );
3. osMap = new OpenSpace.Map('map', options);
We now set the centre of the map and set the initial map zoom level to 1
(corresponding to the second defined layer in the resolutions array).
1. osMap osMap.setCenter(new OpenSpace.MapPoint(40,10), 1);
Cheers

Re: [OpenLayers-Users] Points and Popup shifted on a Google background
Hi,
instead of your declaration
gbase = new OpenLayers.Layer.Google( Google Physical, {type:
G_PHYSICAL_MAP}, {'sphericalMercator': true} );
you have to use
gbase = new OpenLayers.Layer.Google( Google Physical, {type:
G_PHYSICAL_MAP, 'sphericalMercator': true} );
then your map is in spericalMercator. Otherwise it seems, that instead of
your options for the map, the baselayer projection is taken and that is
EPSG:4326.

Betreff: [OpenLayers-Users] Points and Popup shifted on a Google background
Hi again,
I've seen that no attachment can be sent to the list. So I've put the code
at the end of this mail...
-
I've have a problem of misplacement of features and popup when adding a
vector layer to a OL map with a background Google.
I just want ot add some points entered in WGS84 (by OpenLayers.Layer.Vector)
to a map with a Google layer as the base layer. I've put my map in spherical
Mercator, as well as the google layer and I've transformed my points in
EPSG:900913 but I still have a problem!
My points are displayed near the exact location, but with a slight shift.
When I zoom/zoom over or if I pan in the N-S direction, points are changing
of position. Until here, it seems that it is just a projection problem, but
I think I'm doing right in the projection setup(?)
But the most surprising is that the popup, which should be displayed on the
points when clicking on it, are displayed at the exact locations, at any
scale! So the position of the popup are right!
If I try to transfom the points from EPSG4326 to EPSG900913, they are not
displayed anymore anywhere...
I've attached my stand-alone working code.
This identically happen under WinXP-IE7 or FF and Ubuntu-FF.
Any hints are welcome!

Re: [OpenLayers-Users] Way to get name of the feature attribute?
Hi,
If you use an OGC conform WFS server, then you can use
REQUEST=DescribefeatureType
to get the attributes of the features. That are only the ones the server is
configured to return, not all the columns that are probaply in the database.

Betreff: [OpenLayers-Users] Way to get name of the feature attribute?
Hi
I am using WFS-T to add object to the database. Is there a way to get a name
of columns in that database. I mean how to get the name of the attribute. I
am using these code below to add new object to the database.
drawControls = {
add_object:new OpenLayers.Control.DrawFeature(
zielona_wfs, OpenLayers.Handler.Path
)}
drawControls[add_object].featureAdded = function(feature) {
feature.layer.eraseFeatures([feature]);
feature.geometry = new OpenLayers.Geometry.MultiLineString(
feature.geometry
);
selectedfeature=feature;
feature.state = OpenLayers.State.INSERT;
feature.layer.drawFeature(feature);
}
.
function add_object() {
selectedfeature.attributes['Id']
=parseInt(document.getElementById(id_geometry).value);
selectedfeature.attributes['Road'] =
document.getElementById(road_geometry).value;
map.layers[1].commit();
return false;
}
As you can see I am using selectedfeature.attributes['Id']. I would like to
use instead of 'Id' some parameter of feature or wfs layer (zielona_wfs). Is
they a way to get to name of attributes (column in database) through WFS
layer. I would also like to say that this:
var object_attributes = feature.attributes
for (var key in object_attributes)
{
document.write(key);
}
will not work because object_attributes is empty (because I am adding new
object to database, not editing existing one)
Does anyone have any idea??
Thanks,
Poul

Betreff: [OpenLayers-Users] WFS attributes at init()
Hi!
I am able to get name of the attribute and the attribute by clicking on the
feature on map. I am trying to get only the name of the feature, and use
them in init(function), not only in method onFeatureSelect(feature) but also
in init(). Is there a way to get to them by using just the WFS_layer? Of
course I can just write the name of them like id, name. but I want
to get them always from the WFS feature, in case someone change something in
the database. I found about one hundred pages about getting features and
presenting them on popup menu but I could not find anything about my
problem. Does anyone have an idea??

Re: [OpenLayers-Users] help(upload and update files)
Hi,
You have to have one baselayer, so try
lindero.isBaseLayer=true; //after map.addLayer()
To add vectorlayers to your map, you can try something like this:
function addGMLlayer(title, url)
{
var Lindero = new OpenLayers.Layer.GML(title, url, {
format: OpenLayers.Format.GML,
formatOptions: {
'extractStyles': true
}
});
map.addLayer(Lindero);
}
If the gml-files come not from the same domain as your page, then you have
to use a proxy-script.

Re: [OpenLayers-Users] Opacity of GoogleLayer, get selected layer
Hi,
OSM.setOpacity(0.1);
map.addLayers([google, OSM, google_t]);
google.setOpacity(0.1);
google_t.setOpacity(0.1);
The Google layers have to add to the map before you can change the opacity
of the Google layers. For other layers it's possible before adding them to
the map.

Hi Eric, thanks for the fast reply.
With the baseLayer-object it works. I tried to apply the method
directly to the layer, maybe that was the problem.
But still I have the problem, when changing the baseLayer. In my case
I got three baseLayers and no matter which one is selected it should
have a opacity.
If I do it like this:
var map = new OpenLayers.Map(options);
var google = new OpenLayers.Layer.Google(
Google,
{'sphericalMercator': true}
);
var OSM = new OpenLayers.Layer.OSM(OSM);
var google_t = new OpenLayers.Layer.Google(
Google_Terrain,
{type: G_PHYSICAL_MAP, 'sphericalMercator': true}
);
map.addLayers([OSM, google, google_t]);
map.baseLayer.setOpacity(0.5);
the opacity is applied just to the initial baseLayer. The other layers
don't have a opacity after being selected.
I think, thats why I have to trigger the event, wether a layer is
selected or not and set the opacity afterwards.
Maybe it is possible to do so in the treepanel-object of the mapFish-API.
Couldn't find anything appropriate so far, but I have to dig more into it.
If you or somebody else got a hint, I would appreciate it very much.
http://www.openlayers.org/dev/examples/spherical-mercator.html
open the firebug console, and do:
map.layers[0].setOpacity(0.2) // - this changes the opacity of the current
base layer
map.layers[1].setOpacity(0.2) // - this changes the opacity of the Google
Satellite layer, although it's not the current base layer
now select the Google Satellite layer in the LayerSwitcher, its opacity is
expectedly 0.2.
Maybe I don't understand the issue you're having.

Your layer are also displayed in lat/lon, but with your extent you are not
able to zoom near enough. Set every time your bounds, then it should work.

{
options.units='m';

Betreff: [OpenLayers-Users] reprojecting issues
hi all,
please correct me if I'm wrong.
As far as I have investigated around, if I want to reproject all the layers,
I have to first destroy the map, recreate it with options.projection=my_proj
and recreate all the layers (when destroying the map, layers persist but
params are deleted) and add them
Even with some errors (EPSG 32661 and 3411 are not correctly reprojected) it
can be see on http://edit.csic.es/geo/mapviewer/projections_test.html
http://edit.csic.es/geo/mapviewer/projections_test.html
What it doesn't work at all is trying to switch to lat/long (4326), where I
don't get an error but a blank image. Some idea why it happens?
and why 32661 and 3411 are not correctly displayed?
thanks in advance,
Pere

To get geoJSON in return use OpenLayers.Format.GeoJSON():
var formats = {
wkt: new OpenLayers.Format.WKT(),
geojson: new OpenLayers.Format.GeoJSON(),
georss: new OpenLayers.Format.GeoRSS(),
gml: new OpenLayers.Format.GML(),

};
var type = geojson;
//var type = gml;
var theParser = formats[type];
function findcoords (event) {
var data = theParser.write(event.feature);
alert('ID:' + data);
//only relevant for geoJSON, and only one feature
var objData = eval ( '(' + data + ')');
alert(objData[geometry][coordinates]);

Re: [OpenLayers-Users] Problems with SLD_BODY
Hi,
I would suggest, that with your SLD_BODY (6050 chars; more rules, more
chars) the url get too long. I have the same problem with IE. FF seems to
get along.
Instead of SLD_BODY you can perhaps use SLD and write your SLD_BODY into a
file, that is over http reachable.

Re: [OpenLayers-Users] Using only one set of modify feature controls for different layers?
Hi,
It is possible to work with one control set for all vector layers. I have an
application, where i use this.
When changing from one vectorlayer to another, I destroy the controls and
declare them then for the next vectorlayer. But i have my controls set in a
OpenLayers panel. So there is no need for registering events, that's part of
the panel. Perhaps there is the cause, that your approach doesn't work.

Betreff: [OpenLayers-Users] Using only one set of modify feature controls
for different layers?
I added 3 different WFS polygon overlays to the map like this:
var wfs_poly_1 = new OpenLayers.Layer.Vector(WFS POLY 1, {
strategies: [new OpenLayers.Strategy.BBOX()],
protocol: new OpenLayers.Protocol.WFS({
version: 1.1.0,
url: /geoserver/wfs,
featureType: 'LAYER_PREFIX.WFS_POLY_1',
featureNS: http://geoserver.sf.net;,
featurePrefix: sde,
srsName: EPSG:900913,
geometryName: SHAPE
})
});
wfs_poly_1.setVisibility(false);
var wfs_poly_2 = new OpenLayers.Layer.Vector(WFS POLY 2, {
strategies: [new OpenLayers.Strategy.BBOX()],
protocol: new OpenLayers.Protocol.WFS({
version: 1.1.0,
url: /geoserver/wfs,
featureType: 'LAYER_PREFIX.WFS_POLY_2',
featureNS: http://geoserver.sf.net;,
featurePrefix: sde,
srsName: EPSG:900913,
geometryName: SHAPE
})
});
wfs_poly_2.setVisibility(false);
var wfs_poly_3 = new OpenLayers.Layer.Vector(WFS POLY 3, {
strategies: [new OpenLayers.Strategy.BBOX()],
protocol: new OpenLayers.Protocol.WFS({
version: 1.1.0,
url: /geoserver/wfs,
featureType: 'LAYER_PREFIX.WFS_POLY_3',
featureNS: http://geoserver.sf.net;,
featurePrefix: sde,
srsName: EPSG:900913,
geometryName: SHAPE
})
});
wfs_poly_3.setVisibility(false);
map.addLayers( [ wfs_poly_1, wfs_poly_2, wfs_poly_3 ]);
Then I added the modify controls like this: (by default, wfs_poly_1 is
selected)
modifyControls = {
select: new
OpenLayers.Control.SelectFeature(wfs_poly_1,{
onSelect:
onFeatureSelect,
onUnselect:
onFeatureUnselect,
toggle: true,
clickout:true,
multipleKey:
ctrlKey}),
drag: new
OpenLayers.Control.ModifyFeature(wfs_poly_1,{mode:OpenLayers.Control.ModifyF
eature.DRAG,displayClass:olControlModifyFeatureDrag}),
resize: new
OpenLayers.Control.ModifyFeature(wfs_poly_1,{mode:OpenLayers.Control.ModifyF
eature.RESIZE,displayClass:olControlModifyFeatureResize}),
rotate: new
OpenLayers.Control.ModifyFeature(wfs_poly_1,{mode:OpenLayers.Control.ModifyF
eature.ROTATE,displayClass:olControlModifyFeatureRotate}),
reshape: new
OpenLayers.Control.ModifyFeature(wfs_poly_1,{mode:OpenLayers.Control.ModifyF
eature.RESHAPE,displayClass:olControlModifyFeatureReshape}),
delete_f: new
OpenLayers.Control.SelectFeature(wfs_poly_1,{onSelect:function(feature){vect
or1.destroyFeatures([feature])}})
};
for (var key in modifyControls) {
map.addControl(modifyControls[key]);
}
I also made my own layer switcher that only allows modification of one layer
at a time. When I toggle between the layers, I assign the layer to each of
the modify feature controls:
for(var modify_key in modifyControls) {
var control = modifyControls[modify_key];
control.layer = layer;
}
The following HTML displays the controls:
div id=modifyControlsMODIFY
CONTROLSbr/
img id=select
class=modify_functions
src=./js/img/select-enabled.png alt=Select/
img id=drag
class=modify_functions

Thanks for this alternative Andreas.
I don't know much about sld but I read some threads and it seems to be the
right solution. I'll try to find some goog examples.

Re: [OpenLayers-Users] geojson - Performance issue
Hi,
2000+ features is way too much for rendering in the browser.
if you use mapserver already, then you can also query the layer as WMS
layer, using sld_body with a filter. If your query is complex, use
Layer.WMS.Post instead of Layer.WMS to avoid urls that are too long for IE.
Regards,
Andreas.

Hi,
I created a WMS (mapserver) layer containing 13400 polygons. It loads
in less then 3 seconds. Good.
I need to develop a tool for the user so he can create a custom query
on this layer to retreive specific polygons. In a form, the user
select the parameters and launch the request. Here is the code below.
That works, but it takes minutes to render. Per example, a query that
returns 2482 polygons, In firebug I see that the query runs in less
then 2 seconds.
But, It seems that the creation of the geometries is an heavy task. I
get this warning in FF
I click on Continue several times and then I get geometries in the map.
I guess 2482 polygons is simply too much for a vector layer. If that
is the case, is there another format then GeoJson I could use? Maybe
my approach is totally wrong...
Any comments would be appreciated.
Thanks for your help,
Steve
The code used:
Ext.Ajax.request({
url: 'requeteVulnerabilite.php',
method:'POST',
params: { inddef: cb_inddefValue},
failure: function(){alert(Ca pas marché);},
success: function(result, request )
{
//alert(result.responseText);
vulnerabiliteLayer.destroyFeatures();
var features = new
OpenLayers.Format.GeoJSON({'internalProjection':map.baseLayer.projection,'ex

var bounds;

Have a look at this example

The context option of an OpenLayers.Style object offers the possibility to
style features by own declared functions.

Betreff: [OpenLayers-Users] Zoom-based feature styling
I expect that there's an easy way to do this, but it so far eludes me. I
have an OpenLayers.Layer.Vector object called icons. Each feature in this
layer has two attributes that I need to worry about: type and zoom. There
are fifty different types, and five different zooms, so far. I already have
type-based styling using:
new OpenLayers.Rule({
filter: new OpenLayers.Filter.Comparison({
type: OpenLayers.Filter.Comparison.EQUAL_TO,
property: type,
value: type_1
}),
symbolizer: {
externalGraphic: /path/to/images/1.png,
graphicHeight: 25,
graphicWidth: 25,
graphicOpacity: 1.0
}
}));
I realize I could use max/minScaleDenominator to restrict zooms, but 5x50
rules is excessive. What I'm looking for is something like:
new OpenLayers.Rule({
filter: new OpenLayers.Filter.Logical({
filters: [
new OpenLayers.Filter.Comparison({
type: OpenLayers.Filter.Comparison.EQUAL_TO,
property: type,
value: type_1
}),
new OpenLayers.Filter.Comparison({
type: OpenLayers.Filter.Comparison.LESS_THAN_OR_EQUAL_TO,
property: zoom,
value: map.zoom
})
],
type: OpenLayers.Filter.Logical.AND
}),
symbolizer: {
externalGraphic: /path/to/images/1.png,
graphicHeight: 25,
graphicWidth: 25,
graphicOpacity: 1.0
}
}));
Except where map.zoom is dynamically evaluated, instead of it being
evaluated only when the style is created.
Any ideas or suggestions are appreciated.

Re: [OpenLayers-Users] insert spatial data into mysql
Hi,
If you not want to use WFS-T, you can manuell add your polygons to your db
with a server script.
I do this task by looping through the features of a vector layer, to get the
attributes and geometry of these features and and post them to a server
script. The script uses ODBC to insert the features geometry into my db.
var aspODBC= ...; //server script to insert data into a MS Access MDB
via ODBC
var KATEGORIE = AREAS;
var TABLE = POLYGONS;
function SaveGeometry(vlayer)
{
var featuresCount = vlayer.features.length;
for(var i=0;ifeaturesCount;i++)
{
insertData(table, vlayer.features[i].geometry);
}
clearVectorlayer();
}
function insertData(table, WKTString)
{
var POSITION = WKTString.toString();
var theUrl = aspODBC;
var data = { MODE: INSERT,
TABLE : table,
POSITION : POSITION,
KATEGORIE: KATEGORIE
}
var myAjax = new OpenLayers.Ajax.Request(
theUrl,
{
method: 'post',
data: OpenLayers.Util.getParameterString(data),
headers :
{ Content-Type: application/x-www-form-urlencoded
},
onComplete: showResponseINSERT,
onFailure: showResponseFailureINSERT
});
}
Updating and deleting features are also possible in this way. And with
MapServer and ogr-ODBC it's possible to retrieve this data via WMS or WFS.

Re: [OpenLayers-Users] rendering WFS and vectors based on zoom levels
minScale and maxScale or minResolution and maxResolution should do the
trick.
function layerGML_BW(title, url, projection)
{
var lyr = new OpenLayers.Layer.Vector(title , {
minScale : 4000,
maxScale : 50,
projection: projection,
strategies: [new OpenLayers.Strategy.Fixed()],
protocol: new OpenLayers.Protocol.HTTP({
url: url,
format: new OpenLayers.Format.GML({
extractAttributes: true
})
})
});
return(lyr);
}
from http://gis.ibbeck.de/ginfo/apps/planwerk/planwerk_nordbahntrasse.asp
if you zoom into the small recangles, a layer with labels will show up.

Betreff: [OpenLayers-Users] rendering WFS and vectors based on zoom levels
I figured out how to render WFS from my website using a proxy. The browser
will send a request like this
to the server:
Parameters: {url=http://mysite.com?typename=topp%3Astates
http://mysite.com?typename=topp%3AstatesSERVICE=WFSVERSION=1.0.0REQUEST=
GetFeatureSRS=EPSG%3A4326BBOX=-570.9375,-457.646484375,819.84375,380.47851
5625
SERVICE=WFSVERSION=1.0.0REQUEST=GetFeatureSRS=EPSG%3A4326BBOX=-570.9375
,-457.646484375,819.84375,380.478515625}
Suppose I only want the content rendered through WFS to only be visible at
lower zoom levels, is there a way to indicate this in openlayers in the
constructor for the WFS layer ?
I would like to also be able to do that for any other vector data as well.
I could do this in a variety of ways using session data through a cookie or
by somehow checking the map zoom level whenever the map moves. In the case
of WFS, maybe I could somehow figure out the zoom level from the bounding
box, but if there is a more transparent way to do that I would like to do it
that way or whatever is the preferred cleaner approach, etc.
