CFGeom

A Python Reference Implementation for Representing Geometries in NetCDF Following the CF Conventions

This project demonstrates how points, lines, polygons, and their multipart equivalents can be represented in NetCDF-CF. The project includes a Python reference implementation for reading and writing geometries in a netCDF file.

For more on this project, see the documentation, or get started with the tutorial.

To view the geometries specification including examples, see Chapter 7 of the CF Conventions.

Use Cases

• Encode watershed model time series and polygons in a single file to archive model output and geometry.
• Encode a streamflow value for each river line in the conterminous U.S. at a given point in time.
