Match up dataset generation for Earth Observation satellites

eomatch

Match up dataset generation for Earth Observation satellites.

eomatch identifies and indexes instances where two satellite scenes overlap in space and time, builds collocated datasets from them, and manages the results as versioned STAC catalogues.

Warning: This software is in beta. Results should be used with caution. Please share any feedback via the issue tracker.

Usage

Virtual environment

It is always recommended to use a virtual environment for each Python project. Use your preferred environment manager, or create one with:

python -m venv venv

Activate it on Windows with venv\Scripts\activate, or on macOS/Linux with source venv/bin/activate.

Installation

Install the package and its core dependencies:

pip install -e .

Optional extras are available depending on your use case:

pip install -e ".[ingest]"   # pgSTAC database ingestion (pypgstac)
pip install -e ".[query]"    # STAC API querying (pystac-client)
pip install -e ".[enrich]"   # Geometric and solar-angle enrichment
pip install -e ".[dev]"      # Development tools (ruff, mypy, pytest, …)
pip install -e ".[docs]"     # Documentation build (sphinx, …)

To install all extras at once:

pip install -e ".[ingest,query,enrich,dev,docs]"

Development

Install the pre-commit hooks after cloning:

pre-commit install

When you commit, ruff will lint and format your code. If it makes corrections the commit will be aborted so you can review the changes — just commit again once you are happy.

Run the test suite with:

pytest

Compatibility

eomatch requires Python 3.11 or later and is tested on Python 3.11, 3.12, and 3.13.
