B4A Library Navigation Library

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.
