I'm assuming that when the project says you can see 24 km from a given location, that you can see 24 km from that location. That's not the case. Fundamentally, it doesn't do what it claims to do.

Why allow the user to select any arbitrary location on a map and give an answer when you know the answer is most likely nonsense? You don't need to compute for 2 days to accomplish that; you could just make it up.

Surely you understand it's based on limited resolution data, and therefore intended to be used at the scale of general topography like mountains and valleys?

That it's not taking into account human construction or distances of tens of meters?

Presumably you can walk a little bit and climb on someone's roof to see the claimed 24.7 km. Assuming a sufficiently clear atmosphere, and that there isn't a tall office building in the way or something.

Why not complain that there's a point inside somebody's basement and you can't see any distance from that? Why not complain that it's wrong any time you close your eyes? Those would be about as sensible.
