SpatialIntersects

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

The Intersects predicate returns the set of features from one layer that intersect features in another layer; this includes any amount of intersection and returns the original feature in its entirety.

Parameters:

  • aLayer1 (GM_LayerHandle_t32) – First layer in predicate

  • aLayer2 (GM_LayerHandle_t32) – Second layer in predicate

  • aParams (GM_SpatialOps_Params_t) – Parameters

Returns:

Error Code

Return type:

GM_Error_t32

Note

This can include various scenarios such as, one geometry (polygon, line, point) completely containing another, geometries touching at a single point or along a line, and overlapping features.
