For geologic features (cliffs, mountains), scenario 1 makes sense to me.
For non geologic features features (walls, buildings) scenario 2 makes
sense.  In general, 'ele' should refer to the elevation of the Earth's
surface above sea level at the given location. It shouldn't really have to
do with "low" and "high" but rather the Earth's surface.
