UBC Geophysical Inversion Facility
Doug Oldenburg's team at UBC specializes in inversion of potential fields, electrical and electromagnetic data. There are some nice case histories on this site.
Consortium for Electromagnetic Modeling and Inversion
GPX Geophysical Exploration Services
Geological and geophysical exploration software, including potential fields and EM modeling. ENCOM also supplies the Discover add-on for MapInfo.
Dirk Kassenaar's VIEWLOG program is one of the most popular geophysical log analysis programs on the market.
Mapping and data processing software for geophysics, geochemistry and drill-hole information.
Forward and inverse modeling software for nearly every geophysical technique known to mankind.
Makers of the well-known MT/AMT/CSAMT interpretation software. Geotools now markets gravity processing and interpretation software.
Free MT processing, forward and inverse modeling software for academic use. Amongst other things, you will find a link to Constable's Occam smooth 1D and 2D inversion codes. These codes are "academic grade", but work well if you have the patience to experiment a little.
