Geotools Corporation - Geophysical Software for Magnetotellurics (MT) and Gravity.Javity - A Bouguer Gravity Modelling Program - Javity is a geophysical profile method for modelling Bouger Gravity anomalies, the modelling being a part of the interpretation process wherein one attempts to explain causative density anomalies in terms of a geological structure. Javity models geological bodies using the n-sided, finite-strike-length polygonal body.
