Radiant Earth Foundation releases its STAC API 1.0
By Chris Holmes, Radiant Earth Foundation
Radiant Earth Foundation has released its first Spatio Temporal Asset Catalogue (STAC) API as version 1.0.0-beta.1. The STAC specification provides a common language to describe a range of geospatial information, enabling online search and discovery of geospatial assets.
Radiant Earth Foundation released the API independent of its STAC Core (i.e. content) releases, and aligned it more closely with the OGC API — Features. This led them to reorganise their repository and restructure their OpenAPI documents to reflect that new structure and lay the groundwork for future improvements.
Major improvements include that services will need to declare their conformance. The way that the specification is built and served has also been changed, with a new Continuous Integration system publishing the resulting files (both dev changes and released versions) to github pages. In trying to make its OpenAPI fragments more reusable, Radiant Earth Foundation made a “fragments” folder that contained OpenAPI yaml files that could be reused in other extensions.
Coming releases will focus on building additional functionality, such a pull request to enable collection-only STAC API’s, using CQL to replace STAC’s custom filtering language and enabling the search of collections. Future updates will also look to improve developer friendliness and refining Conformance Classes.
