[mapserver-users] GRASS GIS layers -help!

[Daniel Morissette]

Gary,

With POINT/LINE/POLYGON layer types, MapServer tries to open the DATA as 
shapefiles by default, that's why you get that error message. Assuming 
your GDAL/OGR is built with GRASS support, then you should use 
"CONNECTIONTYPE OGR" in your layer definition, and specify the path to 
the dataset in the CONNECTION parameter.

More info on CONNECTIONTYPE OGR is available at:
