# GEOF Planet
A configurable spherical geodesic grid data model designed for simulations.
- GEOF Planet is largely based on the [Spherical Geodesic Grids technique](http://kiwi.atmos.colostate.edu/BUGS/geodesic/) described by Todd D. Ringler, Ross P. Heikes, and David A. Randall at the Department of Atmospheric Science at Colorado State University.
