Geometric functions split_partitioned_union_polygon

• split_partitioned_union_polygon(polygon_data_item, relation)

split_partitioned_union_polygon(polygon_data_item, relation) results in a new uint32 domain unit with single polygons for each (multi)polygon in the polygon_data_item argument, and also dissolves over the relation.

attribute polygon_data_item with an ipoint or spoint value type

1. The composition type of the polygon_data_item argument needs to be polygon.
2. The domain unit of the polygon_data_item argument must be of value type uint32.
