SpatialContains

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

The Contains predicate returns the set of features from one layer that wholly contain a feature from another layer. Contain is the opposite of within, i.e. feature A contains feature B if and only if feature B is within feature A.

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

Example

The following is an example of SpatialContains.

spatial_params = gm.GM_SpatialOps_Params_t()
spatial_params.mPredicateResultTarget = gm.GM_PredicateResult_CreateNewLayer
spatial_params.mResultLayerName = "Contains_Result"
err_SpatialContains = gm.SpatialContains(
    layers_list[0], layers_list[1], spatial_params
)
