eodag
EODAG (Earth Observation Data Access Gateway) is a command line tool and a plugin-oriented Python framework for searching, aggregating results and downloading remote sensed images while offering a unified API for data access regardless of the data provider. The EODAG SDK is structured around three functions:
- List product types: list of supported products and their description
- Search products (by product type or uid): searches products according to the search criteria provided
- Download products: download product “as is”
The project is developed in Python. It is structured according to a modular plugin architecture, easily extensible and able to integrate new data providers. Three types of plugins compose the tool:
- Catalog search plugins, responsible for searching data (STAC, OpenSearch, OData, …), building paths, retrieving quicklook, combining results
- Download plugins, allowing to download and retrieve data locally (via HTTP, S3, …), always with the same directory organization
- Authentication plugins, which are used to authenticate the user on the external services used (JSON Token, Basic Auth, OAUTH, …).
