[gdal-dev] OGRGeometry -> OGRGeometryCollection

[Florian Lohoff]

Hi,

i am Intersecting to MultiPolygons and get a OGRGeometry which sometimes
contains a OGRGeometryCollection depending on the complexity of the
overlap. Now i'd like to iterate over the Geometries in the collection
but the OGRGeometry Class does not have the ->removeGeometry or
->getGeometryRef so i'd need to cast the OGRGeometry to a
OGRGeometryCollection. I saw that gdal 2.3 does have a
->toGeometryCollection but i am on Debian/Stretch which has gdal 2.1 
so i am lost on how to extract the geometries of the GeometryCollection
in an OGRGeometry object.

Flo
