globalmapper.SpatialIntersection

globalmapper.SpatialIntersection(GM_LayerHandle_t32 aLayer1, GM_LayerHandle_t32 aLayer2, GM_SpatialOps_Params_t aParams) → GM_Error_t32[source]

The Intersection operation creates a new layer consisting of just the overlapping regions (parts of the original features) in the two input layers, layer 1 and layer 2. New features receive attributes from both layers.

Parameters:

  • aLayer1 (GM_LayerHandle_t32) – First layer in operation

  • aLayer2 (GM_LayerHandle_t32) – Second layer in operation

  • aParams (GM_SpatialOps_Params_t) – Parameters

Returns:
