ORA-13444
        cannot perform mergeLayers operation: string
        
        
        Cause
        The two GeoRaster objects whose layers are to be combined together either had different row or column dimension sizes, or their georeferencing information did not match.
        Action
        Ensure that the objects have the same row and column dimension sizes. If neither is georeferenced, their ULTCoordinate values must be the same. Otherwise, they must be both georeferenced and cover the same area in the model space.
