A python package for creating refinable polyhedral meshes on the sphere. The refinement is either rectangle or triangle based.
The was developed as a component of Graph Neural Networks (GNN) for Geospatial ML projects, and it's designed with that in mind.
The package implements:
- Icosphere
- Octasphere
- Cubesphere
- Uniform Latitude/Longitude
It is also straighforward to extend it to include other triangular/rectangular meshes.
You can find code examples here:
If you're looking to implement your own rectangle/triangle based mesh:
For the full documentation:
- python >= 3.10
- numpy
- scipy (nearest neighbor query)
- trimesh (radius query)
Optional dependencies:
- cartopy (plots)
- shapely (land mask feature)
