Re: [OpenLayers-Users] GeoJSON layer and modifyFeature control
Hi Eric,
I've already passed through something like this. At least the code looks
similar to me. Code is below:
var mycontext = {
getColor: function(feature)
{
var jsonvalue = feature.attributes[fillcolor];
return jsonvalue;
}
};
var contexttemplate = {
fillOpacity: 0.6,
fillColor: ${getColor},
strokeColor:orange,
strokeWidth:1
};
var contextStyle = new OpenLayers.Style(contexttemplate,mycontext);
var myStyleMap = new OpenLayers.StyleMap({default:contextStyle});
var rules = [new OpenLayers.Rule({
symbolizer: contexttemplate,
context: mycontext,
elseFilter: true
})];
myStyleMap.styles[default].addRules(rules);
myStyleMap.styles[select].addRules(rules); (w/ or w/o this line does not
work)
var regions = new OpenLayers.Layer.Vector(regions,{extractAttributes:true,
format: OpenLayers.Format.GeoJSON, projection: new
OpenLayers.Projection(EPSG:4326), styleMap: myStyleMap});
The fill color is not changed accordingly to color I have in GeoJSON file
under attribute fillcolor. All other properties in template are applied. The
edit function does not work.
If I remove {default:contextStyle} from OpenLayers.StyleMap(
{default:contextStyle}); and we remain only with
var myStyleMap = new OpenLayers.StyleMap(); and all rest of code the same,
the edit function works. But still no fillcolor context is applied.
I have also oversimplified the code in a separate page, but result is
identical.
All the best,
Adorian
I added the code below to the modify-feature.html example and it
worked for me (code is based on Alexandre's):
var tpl = {
pointRadius: ${radius},
fillOpacity: 0.4,
strokeColor: #00,
strokeWidth: 2
};
var ctx = {
context: {
radius: function(feature) {
return 10;
}
}
};
var oStyle = new OpenLayers.Style(tpl, ctx);
var oStyleMap = new OpenLayers.StyleMap({
default: oStyle,
// works w/ or w/o the following
select: new OpenLayers.Style({
fillColor: #66ccff,
fillOpacity: 0.2,
strokeColor: #3399ff
})
});
var aoTypeColor = {
'1': {fillColor:blue},
'2': {fillColor:red},
'3': {fillColor:yellow},
'4': {fillColor:white}
};
oStyleMap.addUniqueValueRules(default, Type, aoTypeColor);
oStyleMap.addUniqueValueRules(select, Type, aoTypeColor);
var rules = [
new OpenLayers.Rule({
symbolizer: tpl,
context: ctx,
elseFilter: true
})
];
oStyleMap.styles[default].addRules(rules);
oStyleMap.styles[select].addRules(rules);

[OpenLayers-Users] DrawFeature with callback?
Hi Guys
Im doing a integration for the Apache Wicket framework(
http://wicketstuff.org/confluence/display/STUFFWIKI/wicket-contrib-openlayers
), and want to add some more features. Im looking into adding the
possibility to draw polygons, however I cant find a example where theres
a simple callback involved once the polygon are drawn, however the api
mentions it's possible.
As you can see from the below code the only thing I need for this little
thing to work are the function that calls the alert to be picked up.
Please say if you want me to elaborate further.

[OpenLayers-Users] General question and GML question
Hi everyone, this is about my third time giving OpenLayers a try and this time I thought I would bite the bullet and ask some questions instead of just going back to my mapserver setup. First a general best approach question. What I want to do is use google data and put a simple polygon boundary on top. That boundary is currently in a shape file. My thinking was to convert the shp file to gml and just add it as a layer. I have since read that this maybe tricker then I thought as google data is in a mercator projection that does not have an EPSG code. So then I thought I would just create the projection and project my data to match it in another application before converting it to gml. So my question, is this the best approach, or is there a better way? I could use WMS, but I prefer not to require a wms server to host the local data. Second more specific to the use of GML layers. I converted my shp file to GML using gvSIG and in another attempt shp2gml from spatial order. I cannot get my GML file to be viewable. Thinking it might be a projection issue I thought I would just display my GML file on its own, to avoid any conflicting projections, but that hasnt worked either. Using the gml-layer.html example I tried to work backwards and put my GML file in there, no luck. So my two part question in this regard is: Is there a required element in the GML file that perhaps my GML files are missing? With the gml-layer.html example, if I remove the WMS base layer it will stop displaying the example GML data. Why is that? How can I display GML data by itself for testing purposes?

[OpenLayers-Users] Support for GeoRSS polygons in different spatial refs
Hi, Can anyone give me some light on how OpenLayers can handle GeoRSS. I would like to show Polygons in EPSG:2400 without any transformation. The map is also n EPSG:2400. Reading the documentationI I guess it is only Points that could be used by the GeoRSS-layer in OL and no referencesystems could be defined. Is this GeoRSS Simple that the Layer-type GeoRSS can read and render? Is there no support for GeoRSS-gml? When looking into the sample http://www.openlayers.org/dev/examples/vector-formats.html I can see that the GeoRSS layer is used to read GeoRSS -data but it is rendered by a vectorlayer. Is this still geoRSS-simple? If I want to show polygons with GeoRSS OL should I then use the same method as in the example above or is there an other way? If anyone could describe this then I would be very happy. -- mvh Michael -- MetaGIS AB Michael Östling Mob: 070-279 19 76 Tel: 023 - 702 20 10 ePost: [EMAIL PROTECTED] SKYPE: MichaelOstling MSN: [EMAIL PROTECTED] www: http://www.metagis.se Adress: Britsarvsvägen 28a, 791 36 FALUN, Sweden Org Nr: 556638-7170 -- ___ Users mailing list Users@openlayers.org http://openlayers.org/mailman/listinfo/users
Re: [OpenLayers-Users] WFS popup alignment
Hi Andrew,
I did eventually figure out that it was the spherical mercator problem,
again, though I was/am confused as to why the popup would be placed correctly
yet the feature it was derived from was not!
Unfortuntely, it's not always possible to get enough access to alter the epsg
file and add 900913 support for mapserver. For example, you may have access to
only the web folders on a server (from personal experience). In those cases,
you have to find a different solution to the problem, although of course you
can use different background imagery and eschew the commercial layers...
Thanks again

Hello Joanne:
I am headed out of the office but wanted to give you something to
considerhave you read: http://docs.openlayers.org/spherical_mercator/ which
discusses projection issues using google, yahoo, ve, etc with user created
layers.
Also, I am working on projection issues as well. I started a post which
discusses projection issues which may help you with yours. If you go to my
layer intialization script (
http://webmap.rthicksconsult.com/c2corgCreateMap_projection.js ) you will see
how I had to add {'shericalMercator':true}. As an example
gsatellite = new OpenLayers.Layer.Google(Google Satellite,
{type:G_HYBRID_MAP, 'sphericalMercator': true, buffer:0} );
map.addLayer (gsatellite);

http://www.nabble.com/Cannot-display-search-marker-when-projecting-layers-to-EPSG-900913-td20771840.html#a20771840
.
Hope this will give some insight to your issue.

Hi List,
I have both WMS and WFS layers from a postgres table (starting with WMS but
moving to WFS as you zoom in), on top of Microsoft Virtua Earth. You click the
WFS points and get a framedcloud popup of the feature attribute data. This
aspect works fine, but there is an issue with the alignment of the WFS points.
There are some zoom levels where I can see that the WFS layer does not align
correctly with the WMS, this is worse at the bottom of the map square and
better towards the top. Not only that, the anchor for the popup aligns
correctly with the WMS rather than the WFS. So you click on a point and the
popup appears next to the correct location rather than where you have clicked.
I assume this is something to do with projections, but I'm a little stuck and
would appreciate some assistance. I can't show the map itself because it isn't
available to the outside world, but the salient bits of the code are here:
var map, ve, wms, wfs, drawControls, selectControl, selectedFeature;
function onPopupClose(evt) {
selectControl.unselect(selectedFeature);
}
function onFeatureSelect(feature) {
selectedFeature = feature;
var projcode = selectedFeature.attributes['projcode'];
var sitecode = selectedFeature.attributes['sitecode'];
var projnam = selectedFeature.attributes['projnam'];
var year = selectedFeature.attributes['year'];
popup = new OpenLayers.Popup.FramedCloud(info,
feature.geometry.getBounds().getCenterLonLat(),
null,
div style='font-size:.8em'Project Code:
+ projcode +br /Site Code: + sitecode+br /Project Name: + projnam +
br /Year: + year + /div,
null, true, onPopupClose);
feature.popup = popup;
map.addPopup(popup);
}
function onFeatureUnselect(feature) {
map.removePopup(feature.popup);
feature.popup.destroy();
feature.popup = null;
}
function init(){
map = new OpenLayers.Map('map');
ve = new OpenLayers.Layer.VirtualEarth( Virtual Earth,{'type':
VEMapStyle.Hybrid});
wms = new OpenLayers.Layer.WMS(OA Sites WMS,
http://10.0.10.106/cgi-bin/mapservpostgis.cgi?; ,
{layers: 'oasites', transparent: true, format:
'image/png', buffer:0},
{isBaseLayer: false, reproject: true},
{scales: [1400,50]});

Re: [OpenLayers-Users] DrawFeature with callback?
There seems to be only cancel and done as callbacks for
OpenLayers.Handler.RegularPolygon, but how to use them I don't have a clue.
The done callback is declared in OpenLayers.Control.DrawFeature to draw
the feature, trigger featureadded and call a empty function featureAdded.
This function you can declare to do something after the feature is added to
the layer.
polygonControl.featureAdded = function() { dosomething();};
or (not tested) you can register the event featureadded to the control.

Hi,
I presume you have to specify the event name somehow. Try including this:
dosomething = function (feature)
{
}
...callbacks: {'featureAdded': dosomething}...

As you can see from the below code the only thing I need for this

Re: [OpenLayers-Users] WFS popup alignment
If you use OpenLayers.Layer.MapServer you can use the parameter
map_projection to change the projection on the fly.

Betreff: Re: [OpenLayers-Users] WFS popup alignment
Hi Andrew,
I did eventually figure out that it was the spherical mercator problem,
again, though I was/am confused as to why the popup would be placed
correctly yet the feature it was derived from was not!
Unfortuntely, it's not always possible to get enough access to alter the
epsg file and add 900913 support for mapserver. For example, you may have
access to only the web folders on a server (from personal experience). In
those cases, you have to find a different solution to the problem, although
of course you can use different background imagery and eschew the commercial
layers...
Thanks again
Jo

Subject: Re: [OpenLayers-Users] WFS popup alignment
Hello Joanne:
I am headed out of the office but wanted to give you something to
considerhave you read: http://docs.openlayers.org/spherical_mercator/
which discusses projection issues using google, yahoo, ve, etc with user
created layers.
Also, I am working on projection issues as well. I started a post which
discusses projection issues which may help you with yours. If you go to my
layer intialization script (
http://webmap.rthicksconsult.com/c2corgCreateMap_projection.js ) you will
see how I had to add {'shericalMercator':true}. As an example
gsatellite = new OpenLayers.Layer.Google(Google Satellite,
{type:G_HYBRID_MAP, 'sphericalMercator': true, buffer:0} );
map.addLayer (gsatellite);
My thread is at
http://www.nabble.com/Cannot-display-search-marker-when-projecting-layers-to
-EPSG-900913-td20771840.html#a20771840 .
Hope this will give some insight to your issue.

Hi List,
I have both WMS and WFS layers from a postgres table (starting with WMS but
moving to WFS as you zoom in), on top of Microsoft Virtua Earth. You click
the WFS points and get a framedcloud popup of the feature attribute data.
This aspect works fine, but there is an issue with the alignment of the WFS
points. There are some zoom levels where I can see that the WFS layer does
not align correctly with the WMS, this is worse at the bottom of the map
square and better towards the top. Not only that, the anchor for the popup
aligns correctly with the WMS rather than the WFS. So you click on a point
and the popup appears next to the correct location rather than where you
have clicked.
