EOMAJI OpenEO Toolbox

This repository contains openEO workflows for various python modules used in Evapotranspiration (ET) modeling and Irrigation mapping.

Following modules are currently included:

• Data Mining Sharpener (pyDMS)
• Two Source Energy Balance (TSEB)

Installation

• first install GDAL on your machine
• Then install the package from Github

  pip install eomaji@git+https://github.com/DHI/EOMAJI-OpenEO-toolbox.git
  

Running the Evapotranspiration Workflow

The notebooks provided in the notebooks/ folder demonstrate how to use the EOMAJI OpenEO toolbox for evapotranspiration modeling.

These notebooks can be run directly on Copernicus Data Space (CDSE) JupyterHub for efficient processing and scalability.

Available Notebooks

• notebooks/pydms_example.ipynb – Demonstrates how to use the Data Mining Sharpener (pyDMS) to refine Sentinel-3 Land Surface Temperature (LST) using Sentinel-2 reflectance data.

• notebooks/et_input_parameters.ipynb – Focuses on downloading and preprocessing meteorological and biophysical input data. This includes:

  • Retrieving meteorological parameters from the Copernicus Climate Data Store (CDS).
  • Extracting vegetation indices and land cover parameters from Sentinel-2 and ESA WorldCover datasets.

• notebooks/et_tseb.ipynb – Runs the Two Source Energy Balance (TSEB) model to estimate evapotranspiration. It takes as input:

  • Sharpened LST from pyDMS.
  • Preprocessed meteorological and vegetation parameters.

These notebooks form a complete workflow, from data retrieval and preprocessing to sharpening LST and running the ET model.

Development

For development, you can set up the environment in one of two ways:

1. Using a Dev Container This repository includes a devcontainer setup, which provides a pre-configured environment for development.

2. Manual Setup If you prefer a local setup

   • Install GDAL
   • Create a virtual environment and install the package:

       python -m venv eomaji-env
       source eomaji-env/bin/activate # On Windows, use `eomaji-env\Scripts\activate`
       pip install .
