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?

Re: [mapserver-users] VRT / CSV data sources are not displayed in a layer
Stefan, I asked you about your MAP definition to do some tests. This is what I tried and it works: It seems that you have to consider the following: 1. The name of the CSV file has to be the same as the layer name (layer boden and file name boden.csv). 2. You have to add the SrcLayer tag into your VRT file like this: OGRVRTDataSource OGRVRTLayer name=boden SrcDataSourceboden.csv/SrcDataSource SrcLayerboden/SrcLayer GeometryTypewkbPoint/GeometryType GeometryField encoding=PointFromColumns x=x-utm y=y-utm/ /OGRVRTLayer /OGRVRTDataSource Try it !

Re: [mapserver-users] Field type
Berend, The fields are represented as strings in MapServer so the field types cannot normally be obtained in MapScript. In case of a shapefile layer you could probably create a shapefileObj and use getDBF to obtain a DBInfo object and use DBInfo.getFieldType to retrieve the type of a specific field. However this option is not widely used and you might want to use the GDAL/OGR bindings instead.

Re: [mapserver-users] VRT / CSV data sources are not displayed in a layer
Stefan, I would suspect that your .vrt file contains relative rather than absolute paths and that they are relative to a different working directory if used from MapServer. There is an attribute for the SrcDataSource that may address this. It might help if you posted the VRT. 2010/1/20 Stefan Schantz sscha...@bfs.de: Hello List, The following layer uses a CSV-file (together with a VRT-File (Virtual Format) ) as datasource .

[mapserver-users] PHP layer-updateFromString problem setting type and symbol name
I really like the updateFromString functions in Mapserver Mapscript. I've
eliminated my .map files, instead storing the layer definitions in a database
and drawing them on-demand using PHP. However, I've found a few values
($layer-type and $style-symbolname) that aren't correctly set using Mapserver
5.6.1 (also tried 5.4.2). Here's an example:
?php
$mapDef=MAP
NAME 'test'
SIZE 400 400
EXTENT 0 0 100 100
END
;
$layerDef=LAYER
NAME 'Airports'
STATUS ON
TYPE point
FEATURE POINTS 10 10 50 50 1 50 70 10 END END
CLASS
STYLE
SYMBOL 'airport.gif'
END
END
END;
$oMap = ms_newMapObjFromString($mapDef);
$oLayer=ms_newLayerObj($oMap);
$oLayer-updateFromString($layerDef);
//First problem: returns -1
//echo $oLayer-type;
//$oLayer-set(type,MS_LAYER_POINT);
//Second problem is that the symbol gif isn't used
//unless it is explicitly set again below
//$cls = $oLayer-getClass(0);
//$style = $cls-getStyle(0);
//if($style-symbolname!='')$style-set(symbolname,$style-symbolname);
$oMap-selectOutputFormat('gif');
$img = $oMap-draw();
$img-saveImage(output.gif);

[mapserver-users] SQL Server 2008 layer C# MapScript query help
Hi,
I'm just starting out with MapServer / MapScript C#.
I get Attempted to read or write protected memory when trying to retrieve
the shape of the selection in a SQL Server layer. Code snippet below
(adapted from example code):
if (layer.queryByPoint(Map, point, mapscript.MS_SINGLE, tolerance) ==
(int)MS_RETURN_VALUE.MS_SUCCESS) {
resultCacheObj result = layer.getResults();
if (result.numresults 0)
{ int shapeInd =
result.getResult(0).shapeindex;
layer.open();
shapeObj shape = layer.getFeature(shapeInd, -1);
--Attempted to read or write protected memory
string txt = ;
for (int i = 0; i shape.numvalues;i++)// layer.numitems; i++)
{
txt += b+ layer.getItem(i) +: /b;
txt += + shape.getValue(i) +
br/;
} etc.
Additional notes:
* the tolerance 0
* IIS 5
* using latest build (MSVC2008 (Win32) -stable
release-1500-gdal-1-6-mapserver-5-6.zip) DLLs (including
msplugin_mssql2008.dll)
* VS 2008 project
* the SQL Server layer geometry is points draws without problems
* code works for other layers in may map
Additional issue:
When doing a queryByShape on the SQL Server layer and try drawQuery on the
map I get Image handling error. Failed to draw layer...
Am doing something wrong - is this the correct way of going about querying
visualizing? Is what I trying to do possible with SQL Server layers?
Any help/pointers appreciated.
Thanks
Will
