Distances from N 21 1.700 E 105 51.250:
This tool will help you calculate the distance between two coordinates or a single point and a set of coordinates. I built this primarily to make it easy to check if a Locationless (Reverse) Cache has already been found. Inputs can be in several formats:
All valid waypoints are parsed and their distances from the origin calculated. The results are displayed with the closest ones first.
Additionally, you can map or download the destination coordinate(s).
Thanks to fizzymagic for his distance calculation code.
