Python based machine learning library to use Earth Observation data to map biophysical traits using Gaussian Process Regression (GPR) models. Works with Google Earth Engine and openEO cloud back-ends.

# Features

- Access to GEE/openEO is required. Works best with the Copernicus Data Space Ecosystem. Register [here](https://code.earthengine.google.com/register) or [here](https://docs.openeo.cloud/join/free_trial.html)
 - Hybrid retrieval methods were used: the Gaussian Process Regression retrieval algorithms were trained on biophysical trait specific radiative transfer model (RTM) simulations
- Built-in gap-filling to avoid cloud covers
- Runs "in the cloud" with the GEE/openEO Python API. No local processing is needed.
- Resulting maps in .tiff or netCDF format

# Get started

Refer to the [Documentation](https://pyeogpr.readthedocs.io/en/latest/pyeogpr.html) for instructions and examples.


# Satellites and biophysical variables

You can select from a list of trained variables developed for the following satellites:

[Sentinel-2 L1C](https://pyeogpr.readthedocs.io/en/latest/sensors.html#)

[Sentinel-2 L2A](https://pyeogpr.readthedocs.io/en/latest/sensors.html#)

[Sentinel-3 OLCI L1B](https://pyeogpr.readthedocs.io/en/latest/sensors.html#sentinel-3-ocean-and-land-colour-instrument-olci)
<!-- TODO: Update Docs for Landsat 8 -->
