GEEC (Gal Eötvös Earth Calculator) is an open-source software to compute the gravity and the full-tensor gravity gradient due to a body mass of uniform density with arbitrary geometry. It implements analytical solution of gravity by Singh and Guptasarma (2012) and a new analytical solution by Saraswati et al (2019), that is based on a transition of the general expressions from surface to line integrals.
It is tested successfully for various measurement distances and body mass sizes, enabling applications from local geophysical prospecting to global topographic effect for satellite data. Due to its flexibility, the new solution, and the associated software, is particularly well suited for joint analyses of all types of gravity measurements regardless of the extent, altitude and irregularity of their spatial distribution.
