Hi, I feel I am really asking a stupid question here. So please just
discard if it makes you laugh.
I have a pair of lat-long. My assumption is that my area is very small,
like in a city.
1)Is there a simple equation I can use to calculate the distance in
meters of those two points?
2)If I do d = sqrt [ sqr(p1.lat - p2.lat) + sqr(p1.long - p2.long)], does
d mean anything at all?
