Has anyone written any libraries for Geographic functions within rev?

Im thinking of a library for dealing with latitude and longitude, for
example  determining distance between points, bearings radian calculations


Compute true course and distance between points.

Compute lat/lon given radial and distance from a known point.

With default ellipsoid to WGS84 and other types.


This could be useful for creating some mapping functions within rev, but
also for 3d users for real world visualisation.

Might be handy for GPS logging also.


Has anyone done anything similar, or is there any interest in such a
