Gravimetric-inversion, Wiener-filter, Satellite-data

The goal is to write a software that is able to model the discontinuity surface between Earth crust and mantle from satellite gravimetric observations. This surface is called Moho. It is required to read the gravity data from an online service (http://icgem.gfz-potsdam.de), to strip the data under the assumption of a two-layer model and finally to solve the inverse gravimetric problem through an iterative Wiener filter procedure in planar approximation. The output surface has to be properly visualized, together with the error estimates.
