This document lists the various implementations of the SpatioTemporal Asset Catalog specification. Contributions to the spec should be based on experience building API's for imagery and other geo-asset catalogs, so suggested changes / improvements to the spec should be based on some software listed here. All listed implementations should have a link to a live server or static catalog that indexes real data, though they do not have to production ready or have any guarantee of uptime. If a live server is not possible then a link to open source code is also acceptable.
This section is links to live catalogs (both static and active) that have data.
- None available yet - spec is too new.
Open Imagery Network was the first attempt at a static catalog. The OpenAerialMap bucket is in active use. It is planned to evolve OIN and OAM architectures to use static catalogs.
AWS Public Datasets, particularly Landsat, NAIP and Sentinel all get close to the ideas of STAC static catalogs, and hopefully will evolve to implement the standard.
These are pieces of software that can crawl and/or produce static catalogs.
The Catalog Crawler was done during the Boulder Sprint, as an early proof of concept.
Element84 made a clojure implementation of the spec that serves as a lightweight proxy to NASA's CMR, constrained to just data in USGS EROS.
Josh Fix's open-catalog demonstrates generating code from the core swagger spec.
