Fatiando a Terra is Portuguese for Slicing the Earth, a reference to the project’s Brazilian origins and ambitious initial goals to model the whole planet.
Who we are
Fatiando tools are developed by working geoscientists and community volunteers from across the globe.
The maintainers are the ones responsible for leading the projects, merging changes, making releases, and more.
The Fatiando a Terra project had it’s start around 2008 as a C++ program to perform geophysical modeling of various data types (gravity, magnetics, seismic, etc.). At least that was what a small group of Geophysics undergraduate students at the University of São Paulo, Brazil, set out to do. Unsurprisingly, this overly ambitious goal was never achieved.

In 2010, we started developing the
Python library, which included several state-of-the-art methods for forward
modeling and inversion of gravity and magnetic data, as well as toy problems in
other fields useful for teaching.
Development of this library was discontinued in 2018 as our focus shifted to
our newer and more well-scoped libraries.
This blog post announcing the shift explains the
reasoning behind this decision.
The geophysics Python ecosystem
Fatiando is a part of the larger geophysics open-source Python ecosystem, which has grown tremendously since we started development in 2010.
