It is PostGIS document but don't care about that, the knowledge is universal. Instead, be curious and start reading from the previous level http://postgis.refractions.net/documentation/manual-2.0/PostGIS_Special_Functions_Index.html PostGIS is using GEOS and GDAL can be compiled with GEOS, thus the functions can be used in both, even perhaps not exactly the same set. -Jukka Rahkonen- ___ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev

IMO, PostGIS documentation is a mandatory reference while learning GDAL/OGR (geometry).
