## Abstract

The Fatiando a Terra project (https://www.fatiando.org) is a collection of

open-source Python libraries for geophysics that covers a wide range of

functionalities, from data download and processing to modelling and inversion.

Each one of the libraries in the project was designed with their own

scope of applications.

Harmonica is focused on processing and modelling gravity and

magnetic data. It provides tools for gravity corrections like Bouguer and

terrain effects; interpolations and upward continuation through equivalent

sources; Fourier domain filters like vertical derivatives, upward continuation

and reduction to the pole; forward modelling of geometries like prisms, point

sources and tesseroids (a.k.a spherical prisms); and more.

Boule hosts reference ellipsoids useful for applying coordinate

conversions and normal gravity calculations.

Verde offers tools for processing and interpolating any type of spatial data

through a diverse set of methods, with a machine learning inspired approach.

Pooch eases the process of downloading and caching data from the web with

a very simple interface. Lastly, Ensaio offers a set of curated open-licensed

datasets useful for teaching, practicing and probing our codes.

The project started in 2010 in South America as a simple Python library as part

of a PhD Thesis, and has since growth to include a global community of

contributors. Its progress has been facilitated by a consistent effort of

meeting the highest standards in software development. Through the adoption of

best practices and a thoughtful design of its tools, the project provides well

tested and well documented code that is easy to use, regardless of the Python

skills of its users. This has led the project to be used in real world

applications like scientific research and geophysical exploration within

industry and academia.

During this talk we'll provide an overview of the tools in the Fatiando

project, demonstrate their functionalities using examples from research and

industry applications, and take a look at some code snippets to showcase its

capabilities and ease of use.

We will also take the opportunity to discuss upcoming developments, our roadmap

for the future and plans for implementing highly requested features.

## About the speaker

Santiago Soler is an Argentinian Physicist and PhD in Geophysics.

His research is centered on the application of potential fields to geophysical

problems, and mainly focused on the development of new methodologies for

processing and modelling gravity and magnetic fields.

Examples of these are the forward modelling of tesseroids (spherical prisms)

with variable density, and the gradient-boosted equivalent sources technique,

that allows interpolating gridding and upward continuing very large datasets of

gravity and magnetic fields.

In parallel to his research, he is committed to contribute to open-source

scientific software and open science initiatives.

He is one of the core developers of the Fatiando a Terra project: a collection

of open-source Python libraries for geosciences.

Nowadays, he works as a Postdoctoral Research Fellow at the University of

British Columbia, under the supervision of Dr. Lindsey Heagy and within the

Geophysical Inversion Facility group.

His current research aims to characterize serpentinized rock deposits using

joint inversions of gravity and magnetic data in order to assess their

potential for carbon sequestration.

He continues contributing to the open-source geoscientific ecosystem by

participating in the development of Fatiando a Terra and SimPEG, a Python

framework for geophysical inversions.
