[mapserver-users] WFS Layer + C# map script

[Murty Maganti]

Hi Assefa

Yes, the problem seems to be related to the GML file not accessible. I
normally leave WEB->IMAGEPATH empty in my map files as my application
displays map image on a windows form directly. When I started adding
support for WMS layers, I noticed that it is using imagepath to store
temporary files. I didn't want to specify a qualified path as the map
file will not load on other machines which may not have the same path. I
tried "\" (after briefly  scanning through msBuildPath and msBuildPath3
methods) and it worked for WMS. I guess "\" gets resolved to location of
the map file.

But same is not working for WFS. If I change the path from "\" to a
fully qualified path, I don't see that error any more. But I don't want
to use fully qualified path. I want to use any relative path that can be
resolved to map file path or shappath or any other location. What is the
best relative path I can use for imagepath that can work for WMS/WFS or
any other data sources that use this to store temporary files.

Thanks
Murty

Hi Murty,

  MapServer does a request to the WFS server to get the GML file. This 
GML file is saved locally  and rendered by OGR as a vector layer.
  You might want to check the file you got from the server (should be 
inside web.imagepath (xxxx.tmp.gml) and see if it is valid or/if can be 
opened with ogr.

Best Regards
