- globalmapper.SpatialRelate(GM_LayerHandle_t32 aLayer1, GM_LayerHandle_t32 aLayer2, GM_SpatialOps_Params_t aParams, str aStr) GM_Error_t32 ¶
The Relate predicate is a useful function that can do various general spatial operations at once, based on the DE-9IM string input aStr. This string should be nine characters long, and consist of T, F, or *, where each character in the sequence represents a part of the operation that can be applied or ignored. For more information building a DE-9IM string, see https://en.wikipedia.org/wiki/DE-9IM.
aLayer1 (GM_LayerHandle_t32) – First layer in predicate
aLayer2 (GM_LayerHandle_t32) – Second layer in predicate
aParams (GM_SpatialOps_Params_t) – Parameters
aStr (str) – The DE-9IM predicate string
- Return type
