Re: [mapserver-users] VRT / CSV data sources are not displayed in a layer

2010-01-20 Thread Stefan Schantz

Well, here is the MAP definition, but the same mapfile works with the 
Shapefile, which I have transformed from the CSV/VRT-files, so I think, 
that the mapfile shouldn't be the issue.

Hello Carlos,
my CSV-file ans VRT-file looks like your examples:

My CSV is
x-utm,y-utm,Wert
  742226.,  5374978., 0.00E+00
  743422.,  5375072., 0.00E+00

...

and my VTR is

  
  /daten/csv/boden.csv
  wkbPoint
  
  


and as I wrote, ogr2ogr could read my vrt/csv data and transform it 
into a shapefile..

Re: [mapserver-users] Announcement: Dracones, a web mapping framework for MapServer

2010-01-20 Thread Barend Köbben

Hi Christian,

Thanks for bringing this. It looks like a very promising framework, but
while checking out your examples I did notice that the client apparently is
not registering a CTRL-click in my setup (Firefox 3.5.7 on MacOSX 10.6),
nothing ahpens (SHIFT-drag and doubleclick work). This makes the client side
app a bit handicapped...

Yours,

I can see where all the settings come fro mthe .PRJ file except for the x_0 and 
y_0, where did these come from?

I though tit might be the "False_Easting"/"False_Northing" settings but 
changing x_0 = 1640416.7 caused the images to disapear so that's not 
it.

If you were just trying to display the data in a simple map, you could go 
without the projection info and still see something if you only wanted to 
display that layer.

Let's add a PROJECTION obj to your layer:

Take a look at http://spatialreference.org/ref/esri/102740/.  I am pretty sure 
that this is the spatial reference system (SRS) that your data is in.  

MapServer uses SRS definitions in Proj.4 format.  Here is a link to this SRS in 
Proj.4:  http://spatialreference.org/ref/esri/102740/proj4/

In your LAYER, add

PROJECTION
   "proj=lcc"
   "lat_1=28.38"
   "lat_2=30.283334"
   "lat_0=27.83"
   "lon_0=-99" 
   "x_0=60.01"
   "y_0=400"
   "ellps=GRS80"
   "datum=NAD83"
   "to_meter=0.3048006096012192"
   "no_defs"
END

Does this work?

Dear MapServer users,

I have created Dracones, a Python and JavaScript web mapping framework
based on MapServer, which I think could be of interest to the open
source web mapping/GIS community. It is available at:

http://surveillance.mcgill.ca/dracones

This framework began its life as a surveillance application for
Montreal Public Health. After a lot of refactoring sessions, I had the
idea of abstracting a set of core client/server services, that would
become the framework, and to rewrite the original application in terms
of those. Thus the set of features offered by Dracones stems from
pre-existing application needs, rather than the opposite.

In a nutshell, here is what Dracones provides..

On the client side:

* A lightweight but powerful map widget (100% JS), with state of the
art features like AJAX-based smooth scrolling and visual selection
* An extension mechanism to define new UI behaviors (e.g. what happens
when clicking on the map, or drawing a selection box around objects)

On the server side:

* A set of Python classes and functions (written on top of
Python-MapScript) that encapsulate the application state, and ease the

I am trying to display the data as a map layer that can overly a Vitural Earth

Some of my shape files that were not working before are now working where 
others are still not, but at least I now have a clue to what the heck I am 
doing!

I'll look at the links you sent me and try to figure out the other files.

If you were just trying to display the data in a simple map, you could go 
without the projection info and still see something if you only wanted to 
display that layer.

Let's add a PROJECTION obj to your layer:

Take a look at http://spatialreference.org/ref/esri/102740/.  I am pretty sure 
that this is the spatial reference system (SRS) that your data is in.  

MapServer uses SRS definitions in Proj.4 format.  Here is a link to this SRS in 
Proj.4:  http://spatialreference.org/ref/esri/102740/proj4/

In your LAYER, add

PROJECTION
   "proj=lcc"
   "lat_1=28.38"
   "lat_2=30.283334"
   "lat_0=27.83"
   "lon_0=-99"

Does this work?

the same projection.  I need to create an srs def ... any sites with examples

The other alternative is to figure out how to create a PROJECTION element in

I think that this is pretty obviously your problem.

Before you can transform between spatial reference systems (SRS), you need to 
know what the original SRS is.  To create VE image tiles, it needs to transform 
to 'Web Mercator'.  It can't do that if you don't correctly identify the SRS of 
your layer.

I believe that your lat/lon layer works because it is inheriting the projection 
from the MAP.  For your 'something else' layer, you will need to define the 
correct projection for that layer.

The Extents on the working file are in lat/lon. In the non-working file it

not sure where to go from here to get the first file to work.

Based on the errors, it looks like you will need EXTENT to your map file at the 
MAP level.

What do you get when you run ogrinfo against the two shapefiles?  Any 
difference?

Are you adding a URL var for the layer name?  Try setting LAYER STATUS to 
DEFAULT for both layers and see if you get an ima

[mapserver-users] Announcement: Dracones, a web mapping framework for MapServer

2010-01-20 Thread Christian Jauvin

Dear MapServer users,

I have created Dracones, a Python and JavaScript web mapping framework
based on MapServer, which I think could be of interest to the open
source web mapping/GIS community. It is available at:

http://surveillance.mcgill.ca/dracones

This framework began its life as a surveillance application for
Montreal Public Health. After a lot of refactoring sessions, I had the
idea of abstracting a set of core client/server services, that would
become the framework, and to rewrite the original application in terms
of those. Thus the set of features offered by Dracones stems from
pre-existing application needs, rather than the opposite.

In a nutshell, here is what Dracones provides..

On the client side:

* A lightweight but powerful map widget (100% JS), with state of the
art features like AJAX-based smooth scrolling and visual selection
* An extension mechanism to define new UI behaviors (e.g. what happens
when clicking on the map, or drawing a selection box around objects)

On the server side:

* A set of Python classes and functions (written on top of
Python-MapScript) that encapsulate the application state, and ease the
interaction with its map objects
* A well-thought extension mechanism, to define custom requests and queries

Dracones also provides a bunch of other application-centric features,
like easy map image export and undo/redo. Last but not least, I've
been very careful in writing the documentation and tutorials, which I
think cover a wide range of issues and possibilities.

This work is still in Alpha stage, and I will be of course very
interested to hear the community's comments and suggestions.

Best regards,

Christian Jauvin

Re: [mapserver-users] VRT / CSV data sources are not displayed in a layer

2010-01-20 Thread Carlos Ruiz

Check that you have your CSV like this:

Lat,Lng,House
48.1,0.25,"My house"
49.2,1.1,"My girlfriend's house"
47.5,0.75,"My mother in law's house"

And that you have your VTR like this:



[FILE]
wkbPoint
[YOUR SRS]

Subject: [mapserver-users] VRT / CSV data sources are not displayed in a layer

Hello List,

The following layer uses a CSV-file (together with a VRT-File (Virtual Format) 
) as datasource . When I try to visualize the layer, nothing is shown (neither 
the data nor error messages; shp2img shows also nothing)

LAYER
   NAME "boden"
   DEBUG on
   STATUS ON
   TYPE POINT
# DATA "/daten/csv/boden/boden" # Datenquelle Shapefile
   CONNECTION   "/daten/csv/boden.vrt"

   END
 METADATA

   "WMS_SRS"   "EPSG:25832"
   "WMS_ABSTRACT""test"

   END

   CLASS
  NAME "test"
  STYLE
   SYMBOL "circle"
   SIZE 15  COLOR 90 90 90
  END
   END   END


But if I transform the CSV/VRT-file into a Shapefile  via ogr2ogr

ogr2ogr -s_srs EPSG:25832 -t_srs EPSG:25832 -f "ESRI Shapefile" boden boden.vrt


the layer displays the data.
What is wrong with my VRT/CSV-datasource in the mapfile?

Thanks for any idea.

2010-01-20 Thread Sandeep Kumar Chauhan


Hi Steve,

 Thanks for help, i changed my code according to your suggestion.

if (layer.queryByPoint(Map, point, (int)mapscript.MS_SINGLE, tolerance) ==
...
{
resultCacheObj result = layer.getResults();
if (result.numresults > 0)
{
resultCacheMemberObj rrr = result.getResult(0);
 shapeObj shape = new shapeObj((int)layer.type);
 layer.resultsGetShape(shape, rrr.shapeindex,
rrr.tileindex);
...
...
...
Now it is working fine. Again thanks for help

Thanks,

Re: [mapserver-users] PHP MapScript pixel coordinates to map coordinates

2010-01-20 Thread Daniel Degasperi


Hi David,

have you already tried with this conversion:

$geo_x = $minx + (($pix_x / $map_width) * ($maxx- $minx));
$geo_y = $maxy - (($pix_y / $map_height) * ($maxy - $miny));

Folks,

This question has no doubt been asked many times, but for the life of
me I cannot find a solution. Here's what I'm trying to do:

I have a jQuery-based front-end that uses the wonderful jcrop
extension (http://deepliquid.com/content/Jcrop.html) that helps
coordinate zoom. I'm hoping to use this same front-end to permit
cropping of a resultant map image, which means I need to pass the four
pixel corner coordinates, convert to map coordinates (projection may
be variable), then set the extent such that the resultant map image
will have the same dimensions as that described by the user on the
front-end. So, how can I convert pixel coordinates to map coordinates?
Note that the map projection is not always DD so I cannot merely use
proportions as I have seen in some solutions. Surely this is easier
than I am making it out to be.

Thanks for any advice,

David Shorthouse

Hi,

Is that possible to use lanczos resample method in mapserver? I can find this 
option in GDAL but not in mapserver.
Thanks!
