Given GRASS great raster function, it is suprising that so few (none?) geophysics applications surfaced so far.

In August, 2008, talks were initiated regarding the creation of modules to address potential field methods.

So far, the iniative has produced some wikipages and tentative "software specs". The initial focus is on [[Gravity]] and [[Geomagnetism]].
