Hi, I exported the geometry to geojson as: OGRMultiPolygon * poOGRMultiPolygon= (OGRMultiPolygon * ) unionCascaded; // char * pszJSon= poOGRMultiPolygon->exportToJson(); this generates: "type": "MultiPolygon", "coordinates": .... But. I need geometrycollection. How can I do that? regards -- Ahmet Temiz Jeoloji Müh.
