FindFeaturesInArea¶
- globalmapper.FindFeaturesInArea([GM_LayerHandle_t32] aLayerList, GM_FindFlags_t32 aFindFlags, GM_AreaFeature_t aAreaToSearch, GM_Projection_t aAreaProj, uint32 aReserved=0) GM_Error_t32, GM_FoundFeatureResults_t [source]¶
Searches the provided list of layers for any visible vector features within the provided area feature. You can find area, line, and/or point features that are completely within the provided area feature.
The results are returned in a GM_FoundFeatureResults_t list. After you are done with it, use FreeFeatureResultList to free the result list.
- Parameters:
aLayerList ([GM_LayerHandle_t32]) – List of layers to search for points or None for all vector layers
aFindFlags (GM_FindFlags_t32) – Flags controlling how the find is performed
aAreaToSearch (GM_AreaFeature_t) – Area feature to search (use GetAreaFeature to get from loaded layer)
aAreaProj (GM_Projection_t) – Projection of coordinates in area feature (use GetLayerInfo().mNativeProj to get layer projection)
aReserved (uint32) – Reserved for future use; defaults to 0
- Returns:
Error Code
- Return type:
GM_Error_t32
- Returns:
Results of find operation (use FreeFeatureResultList to free when done)
- Return type:
