Terrain maps "lowest terrain"??
On our terrain maps we have two figures. The highest peak on the scale and the "lowest" terrain. What is the idea behind that? If I have a 500´ "lowest" hill there is very likely also 400' 300' and lower terrain. Could this be to give us the idea of the countour, i.e. 12000' /400´ would mean a mountainous terrain while 12000´/11000´ could be more like a plateau?
Does anybody have a clue?
