Here is a gathering of ideas, in order to produce geomagnetic modules or scripts to GRASS
Interesting Links
The California Soil Resource Lab has some quite interesting information for production of a Detailed Magnetic Declination map.
They also cite the NOAA website, which has the IGRF and WMM computer models available for download (registration necessary).
The Brazilian National Observatory (ON) also had its own geomagnetic model, which, I've been told, agrees very much with the IGRF, but is calibrated to work only in Brazil. However, I have not been able to find it on their website. I'll try to locate it in my files, then I'll upload it somewhere. (Pmarc)
Wishlist
- Module capable of computing the magnetic field (all 7 components) over a location, for a given date or range of dates. It seems to me (Pmarc) that the most appropriate output would be a vector map. The starting point could be the IGRF model provided by NOAA (link above)
