AddRemovePointToLidarQuery – Global Mapper

globalmapper.AddRemovePointToLidarQuery(GM_LidarQueryHandle_t aLidarQuery, GM_LayerHandle_t32 aLayer, uint64 aPointIndex, bool aAddPoint) → GM_Error_t32[source]

Adds or removes a Lidar point feature at the given index from the layer

Caution: This will close any active iterator on the query, resetting the position of the GetNextLidarQueryPoints call. You can add/remove points from an existing Lidar query created with either the CreateEmptyLidarQuery or CreateLidarQuery functions.

Parameters:

aLidarQuery (GM_LidarQueryHandle_t) – Lidar query to update
aLayer (GM_LayerHandle_t32) – Layer of point to add/remove
aPointIndex (uint64) – Index of Lidar point feature to update
aAddPoint (bool) – Add or remove point?

Returns:

Error Code

Return type:

GM_Error_t32
