The CompGeoLab is a research group based at the Universidade de São Paulo, Brazil. We are experts in solving inverse problems in the field of Geophysics, particularly in gravity and magnetic methods (AKA potential-field methods). Inverse problems are the means by which geoscientists image the inside of the Earth and other planets. For example, we are able to determine the inner density distribution of the Earth from measured disturbances in the Earth’s gravity field. We are also champions of open science and all of our research and teaching efforts are symbiotic with the development of open source software.
Our team works on several tools and projects, both developed in-house and across the larger scientific ecosystem:
- Fatiando a Terra: A collection of Python tools for geophysics. The Fatiando tools are the heart of most of our research and teaching efforts. This is the main project on which we work.
- xlandsat: A small Python library for loading and analyzing Landsat scenes downloaded from USGS EarthExplorer with the power of xarray into xarray.
- The Generic Mapping Tools: One of the most widely used and loved open-source software in the geosciences. Our team contributes to both GMT and the PyGMT library which brings all the power of GMT to the Python stack.
- Tesseroids: A collection of command-line programs for modeling the gravitational potential, acceleration, and gradient tensor. Tesseroids supports models and computation grids in Cartesian and spherical coordinates.
