sat-api

Sat-api is a STAC compliant web API for searching and serving metadata for geospatial data (including but not limited to satellite imagery).

Development Seed runs an instance of sat-api for the Landsat-8 and Sentinel-2 imagery that is hosted on AWS. You can access this at https://sat-api.developmentseed.org. An older version of sat-api can be found on the legacy branch and is deployed at https://api.developmentseed.org/satellites.

Documentation

The documentation includes information on the STAC spec, how to use the API, manage Elasticsearch, as well as how to deploy your own API on AWS. Access the documentation here or on gitbook.

Development

Sat-api includes a number of NPM packages (in the packages/ directory) that are used to create and populate an instance of sat-api. See the sat-utils org on NPM for the full list of packages. Lerna is used for for managing these packages.
