Description
currently, survexport shapefile exports are only in X,Y coordinates. Many georeferencing applications (for example: color by depth in qgis) depend on the Z coordinate as well.
Survex should export 3d shapefiles, potentially optionally.
Some GDAL-bits from #survex chatter:
SHPT=<type>: Override the type of shapefile created. Can be one of NULL for a simple .dbf file with no .shp file, POINT, ARC, POLYGON or MULTIPOINT for 2D; POINTZ, ARCZ, POLYGONZ, MULTIPOINTZ or MULTIPATCH for 3D; POINTM, ARCM, POLYGONM or MULTIPOINTM for measured geometries; and POINTZM, ARCZM, POLYGONZM or MULTIPOINTZM for 3D measured geometries. We want POINTZ and MULTIPOINTZ I think. these are set with a pointer that is the last argument to GDALDatasetCreateLayer()
