Enhance line from gps pos to map center to indicate if line cuts ground

While hiking in the mountain it is sometimes not clear if a certain object on map is visible in real world from current position. Therefore it would be good if line from centered object on map to gps position could mark parts which cut the ground (if elevation data is available for given area) e. g. line color gets red for parts bellow ground level
