A DOS Window program to compile geomagnetic models into GeoMagneticInfo databases. Later see Installing Different Models to decide which model is best for you. Using the Program To use GeoMagneticInfo simply enter the desired location's Latitude and Longitude, and tap Compute. That is, digit, period, and colon. Hopefully the program output is self explanatory.
Declination is the magnetic declination at the specified latitude and longitude.
A magnetic compass reading can be corrected to the direction relative to true north by adding the declination to the compass reading. Inclination is the angle a vertical reading compass will show at the location. Intensity is the magnitude of the magnetic field at the location. Installing Different Models Supplied with this release are 5 geomagnetic models. The later .pdb format is ready to install in GeoMagneticInfo.
