WGS-84 Calculator

Main window
WGS-84 Calculator is used to calculate geodetic distance and azimuth between two points (latitude and longitude). In addition, it can calculate a new point from origin using the given azimuth and distance.

Version 2.11 includes IGRF-12 magnetic model, program calculates magnetic declination for both points and gives results also as magnetic bearings. Declination is calculated using altitude 0.0 m MSL and selected date. Magnetic bearing could be used also when calculationg a new point.

Lat/long values can be inserted using three different formats:

Calculations are based on WGS-84 (World Geodetic System - 1984) co-ordinate system, which is used for example in aviation. Result can be copied to Windows clipboard and then used in other Windows programs.

The WGS-84 Calculator program is very easy to use.
