globalmapper.CreateLidarQuery
=============================

.. currentmodule:: globalmapper
.. py:function:: CreateLidarQuery ([GM_LayerHandle_t32] aLayerList, GM_Rectangle_t aWorldBounds, GM_LidarQueryFilter_t aFilter) -> GM_Error_t32, GM_LidarQueryHandle_t, uint64

    Creates a Lidar query result that you can then perform operations on, like iterating through the points, modifying
    the points, etc. You must call :doc:`FreeLidarQuery<globalmapper.FreeLidarQuery>` to free the memory used by the
    query once done with it.

    :param [GM_LayerHandle_t32] aLayerList: List of layers to search or None for all vector layers
    :param GM_Rectangle_t aWorldBounds: World bounds for search space or None for last drawn
    :param GM_LidarQueryFilter_t aFilter: Optional filter to apply to query (use None if no extra filter)
    :returns: Error Code
    :rtype: GM_Error_t32
    :return: Created Lidar query to be used in future calls
    :rtype: GM_LidarQueryHandle_t
    :return: Number of points matching query
    :rtype: uint64
