About
Boule is Python library for representing reference ellipsoids, 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.
Some examples of where Boule can be applied:
- Storing and manipulating ellipsoid parameters for spherical harmonic analysis.
- Calculating normal gravity for generating gravity anomalies and disturbances.
- Modelling in spherical coordinates, which requires geodetic to geocentric spherical coordinate conversions.
Project goals
- Provide a representation of ellipsoid parameters and derived quantities, including units and citations.
- Convert between geodetic coordinates and geocentric spherical, topocentric, etc.
- Calculate the gravity, gravitational, and centrifugal potential (and its derivatives) of ellipsoids in closed form.
- Include a range ellipsoids for the Earth and other planetary bodies.
Project status
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.

Boule is Python library for representing Reference Ellipsoids, calculating their gravity fields, and converting coordinates defined on the ellipsoids. The main use cases are 1) calculating normal gravity (for gravity anomalies and disturbances); 2) spherical gravity modeling, which requires geodetic to geocentric spherical coordinate conversions; 3) input ellipsoid parameters for spherical harmonic analysis. Boule is French for ball and also a traditional shape of bread resembling a squashed ball (much like the Earth).
