Here is a library to help in navigation tasks:

Convert GEO coordinates to UTM and vice versa.

Calculate the length of a route (a sequence of waypoints)

Calculate the area of a polygon defined by a sequence of waypoints, and btw

Calculate distance and bearing from one point to the other.

The sets of point can be defined either as an array or by a list.

The file contains a demo program.

Have fun

Edit: Ver 1.1 with two additional methods, GeoNextPoint and UTMNextPoint.

Edit: Version 1.2 fixes a bug in SphericalArea and SphericalArea2 methods.
