Overview

STAC is a json-based metadata standard for describing spatial-temporal assets, particularly satellite and Earth observation data. STAC allows users to quickly search, discover and use geospatial assets by providing a consistent structure for query and storage.

The stac_generator can be used as a cross-platform command line interface (CLI) program or a python library that combines automatically extracted geospatial information from raw assets and other user-provided metadata to build a STAC-compliant metadata record for further use. Generated STAC records can be saved locally or behind a STAC API-compliant server.

The stac_generator was developed as part of the Multiscalar Crop Characterisation Project (MCCN). Using the STAC generator to describe an asset collection is the first step in building a datacube with the MCCN engine.

Installation
