SpatialDisjoint – Global Mapper

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

The Disjoint predicate returns the set of features from one layer that do not intersect with any features from another layer. Disjoint features have no overlap between interior or boundary.

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 SpatialDisjoint.

spatial_params = gm.GM_SpatialOps_Params_t()
spatial_params.mPredicateResultTarget = gm.GM_PredicateResult_CreateNewLayer
spatial_params.mResultLayerName = "Disjoint_Result"
err_SpatialDisjoint = gm.SpatialDisjoint(
    layers_list[0], layers_list[1], spatial_params
)
