Hello,
Is there a
method in OpenMap to calculate
the distance between two LatLonPoint’s correctly (for example in
kilometers)?
Thanks,
Hi,
This depends on what you mean by correctly.
LatLonPoint.distance(LatLonPoint toPoint) will return a float that
represents the distance between the two points in radians. Use Length
to convert to any other unit of measurement. This returned distance is
not entirely correct, as it is based on a spherical model of the Earth.
However, the margin of error should be about 0.5%.
If you need to compute the distance more accurately than this I think
you'll have to do it outside OpenMap.
