=======================================

.. currentmodule:: globalmapper
.. py:function:: SetLayerElevationAttribute (GM_LayerHandle_t32 aLayer, str aAttrName, uint32 aReserved) -> GM_Error_t32

    Sets the name of the feature attribute to use for when determining the elevation of a feature. Provide an empty
    string to reset this to the default behavior which searches for any number of known elevation attributes and also
    checks the display name for elevation-based types, like contour lines and spot elevations.

    :param GM_LayerHandle_t32 aLayer: Layer to modify
    :param str aAttrName: Name of attribute to use for elevations
    :param uint32 aReserved: Reserved value for future expansion (must be zero)
    :returns: Error Code
    :rtype: GM_Error_t32
