Interpex offers two software tools that interpret magnetic and gravity profile data. The MAGIX family of software models data in 2, 2. 75 dimensional earth models consisting of bodies and layers whose forward response matches the input data along a single profile line. The magnetic calculations take into account both induced magnetization and possible remanent magnetization. The remanent magnetization is en.

Geoelectrical fields in a layered earth with arbitrary anisotropy. In many cases in geoelectrical exploration, the standard model of a layered isotropic half-space is a good approximation to geophysical reality. But sometimes it is useful to extend this model to uniform anisotropic layers.
