I just wanted to know how did you specify the <GDAL_WMS> service description XML when opening the dataset. Because the error you mentioned sounds like you have an invalid Projection tag in this file.<br><br>Best regards,<br>

How is your <GDAL_WMS>.. service configuration looking like?<br>

<p>Hi There,<br>
<br>
I am using the GDAL build that comes with FWTools2.2.6 (GDAL 1.6.0dev)<br>
to try to open OAM ("<a href="http://openaerialmap.org/static/ww.xml" target="_blank">http://openaerialmap.org/static/ww.xml</a>") using the<br>
C# bindings for GDAL and it throws the following exception:<br>
<br>
<<<<<br>
GDALWMS: Bad projection specified.<br>
>>>><br>
<br>
The source code that causes the exception to be thrown is :<br>
<br>
<<<<<br>
String filename = "<a href="http://openaerialmap.org/static/ww.xml" target="_blank">http://openaerialmap.org/static/ww.xml</a>";<br>
Gdal.AllRegister();<br>
Dataset dataSet = Gdal.OpenShared(fileName,
0); <----<br>
>>>>><br>
<br>
However, I can open and extract pieces of this dataset using gdalinfo<br>
and gdal_translate via the command line. Is this a know limitation of<br>
the C# bindings or am I doing something wrong?<br>
<br>
Thanks, M<br>
<br>
