About Proj4

Simple coordinate converter based on the Proj4 library http://http://trac.osgeo.org/proj

Features:
coordinate conversion,
megnetic declination,
point visualization on maps/earth,
point import from MobileTopographer point lists.

Java wrapper for proj4 by Martin Deruisseaux (2011) http://www.geoapi.org/geoapi-proj4/index.html

The Coordinate Reference Systems bundled in the app are only a few.
If you provide me those for your country, I will add them.

Custom Coordinate Reference Systems can be added to the app (must use proj4 syntax).
