fatiando a terra

"An open-source Python library for modeling and inversion in geophysics. Our goal is provide a comprehensive and extensible framework for geophysical data analysis and the development of new methodologies.

Gravity and magnetics

Modeling, inversion, and processing for potential field methods.
 

3D forward modeling with prisms, polygonal prisms, spheres, and tesseroids. Handles the potential, acceleration, gradient tensor, magnetic induction, total field magnetic anomaly. 

 

Grid manipulation

Functions for generating and operating on regular grids and data that is on a map.
 

Generate regular grids and point scatters. Cut grids and extract profiles. Interpolate irregular data. 

 

Seismology and Seismics

Simple modeling functions for seismics and seismology.
 

Toy problems for: Cartesian straight-ray tomography, VSP, epicenter estimation. Experimental finite-difference wave propagation. 

 

Geometric objects and meshes

Classes that represent geometric objects (points, prisms, polygons, tesseroids) and meshes (regular prism mesh, points on a grid).
 

Standard classes used in all of Fatiando. Efficient classes for meshes that save storage and behave as iterators.
