Boule

Reference ellipsoids for geodesy and geophysics

_images/boule-logo.svg

Boule is Python library for representing reference ellipsoids geometrically, calculating their gravity fields, and performing some global coordinate conversions. “Boule” is also French for “ball” as well as a traditional shape of bread resembling a squashed ball (much like the Earth).

Boule is designed for:

  • Storing and manipulating ellipsoid parameters for spherical harmonic analysis and coordinate system conversions.

  • Calculating normal gravity for generating gravity anomalies and gravity disturbances.

Citing Boule


Boule is ready for use but still changing

This means that we sometimes break backwards compatibility as we try to improve the software based on user experience, new ideas, better design decisions, etc. Please keep that in mind before you update Boule to a newer version.

We welcome feedback and ideas! This is a great time to bring new ideas on how we can improve the project. Join the conversation or submit issues on GitHub.
