Hello, I have one question. Is it the way to get distance of one point from some track? I have reference track and I need this distance - deviation of point from this track. And I need it in meters, so there is problem with translate degrees to meters on Earth.. I need high precission of deviation - deviations are maximally meters. Thanks for reply

Hello, I have one more question about this. How much is this method exactly? Haversine calculate distance on sphere (I think) but Earth is defined as ellipsoid by WGS-84. GPS is using WGS-84, Google Maps is using WGS-84..I am using it too.. but is this calculation of distance right? Thanks for explanation.

Could you post a link please? I can´t find that :-( And is that method really exact? With accuracy in centimeters?
