I found, and will use, if I don't find something else, this method for calculating the distance between 2 lat longs.

Is there a method for this in SharpMap?



Hi Frank, you can project the points onto a planar coordinate system and then distance will be in a linear unit. BTW just to aid in your searching the term for the function for distance between points on a spehere is Haversine formula see http://en.wikipedia.org/wiki/Haversine_formula cheers
