The GeomagInfo is an application for Ewe enabled computers to compute the magnetic declination, inclination, and magnitude for any location on Earth.

Its main use is to give the current magnetic declination to correct a magnetic compass. This application is most useful for those hiking and traveling without topographic maps in unfamiliar territory. A magnetic compass can be off by many 10's of degrees in parts of the world. This application is also useful for correcting the magnetic declination of old topographic maps and navigation charts.

To use this version of GeomagInfo you must install a Ewe VM (Virtual Machine) on your computer. Ewe is a version of Java. It is very compact and efficient. It uses only about 2 Mbytes of memory. To learn more about Ewe please read the introduction on http://davidbray.org/mobile/.
