Hi Thilo, I know nothing about the DP code so I can't comment on that. On Tue, 16 Jun 2009 07:58:24 +0200 Thilo Hannemann <thannema@gmx.de> wrote:
What I do not understand is the distance calculation. Anybody with insight cares to have a look at it (or explain how it works?). I'd assume that a distance calculation on a spherical surface would involve lots of trigonometric functions - which the formula in the code doesn't.
Recently, Coord.distance() was replaced with a much speedier implementation because a lot of cpu cycles were being wasted there. The newer function appears to be accurate enough for our purposes. Cheers, Mark
