I Agree with everything Brian Said!
I Believe Brian pointed out basically everything i can think of for range finding, There's a Perfect quote which is from Jarhead, "You take what you know, and then you multiply. Please don't use your dicks. They're too small, and I can't count that high. I don't wanna hear, "400,000 inches.", So in theory - You could measure out a Small spot of land which you know well, and then use that as a rough guide, This is what i do and its never failed me, least i not forget, Remember that Lighting of course affects range finding, along with dead ground between you and your target, By dead ground i mean ground which you cannot see, due to it being lower than you - Of course you have to account for Wind as well, Which is 99% Luck and 1% Knowledge - However i'll say no more, Correct me if I'm wrong, but good luck in HFT!
