If using ogrinfo, you can set the -geom and -fields parameters, as well documented here [1], for example this will retrieve geometries, but not other fields: ogrinfo -ro WFS:"http://myserver/ows"; mylayer -geom=YES -fields=NO Or, append the PROPERTYNAME GetFeatureInfo's parameter in query string, for example: ogrinfo -ro WFS:"http://myserver/ows?PROPERTYNAME=field1,field2"; mylayer Programmatically, I do not see a way with the API to set this field filters (but I may be wrong), but you could still define a virtual layer, choosing the needed fields you want to select, and then access the layer using the VRT driver. For example: <OGRVRTDataSource> <OGRVRTLayer name="mylayer"> <SrcDataSource>WFS:http://myserver/ows</SrcDataSource> <SrcLayer>mylayer</SrcLayer> <Field name="field1" src="field1" /> <Field name="field1" src="field1" /> </OGRVRTLayer> </OGRVRTDataSource> best regards P [1] http://www.gdal.org/ogrinfo.html -- Paolo Corti Geospatial software developer web: http://www.paolocorti.net twitter: @capooti skype: capooti _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
