Description
Reported as http://georezo.net/forum/viewtopic.php?id=67932
OGRGeometryFactory::createFromGEOS() always return a 2D geometry. The solution is to call the WKB writer with the right coordinate dimensions, however the GEOSGeom_getCoordinateDimension() has only been introduced in GEOS 3.3.0 (unreleased for now). I had imagined a workaround where the callers of createFromGEOS() would give it the coordinate dimension as a hint, being the max of the coordinate dimensions of the input geometries passed to the GEOS operations. A bit complicated and it seems that GEOS < 3.3 didn't preserve well coordinate dimensions from what I've understood from the recent posts of Frank on geos mailaing list.
