SpatialUnion¶
- globalmapper.SpatialUnion(GM_LayerHandle_t32 aLayer1, GM_LayerHandle_t32 aLayer2, GM_SpatialOps_Params_t aParams) GM_Error_t32 [source]¶
The Union operation creates a new layer consisting of all regions from the two input layers. Regions that overlap are split from their containing features. Attributes of non-overlapping regions will come from their original layer; attributes from overlapping regions will come from the features that participated in the overlap.
- Parameters:
aLayer1 (GM_LayerHandle_t32) – First layer in operation
aLayer2 (GM_LayerHandle_t32) – Second layer in operation
aParams (GM_SpatialOps_Params_t) – Parameters
- Returns:
Error Code
- Return type:
GM_Error_t32
