Catalogue
The Archive is where the data lives. The Catalogue is how you find, view and download it.
The Catalogue provides a searchable browser-based frontend to access data stored in the Archive. It also supports all STAC-compliant OpenAPI endpoints to query the Catalogue.
- Searchable index to your FarEarth data
- Indexes products transparently, regardless of format or metadata structure
- Enables fast spatial, temporal and free-text search across massive Archives
- Groups products into STAC Catalog collections (created on the fly)
- Catalogue interface lets you preview images, view metadata and Reports, and download data from the Archive
- Edit and delete products and assets (with suitable permissions)
All products in FarEarth are STAC compliant. The Catalogue also supports integrating external STAC catalogues transparently.
We have extended the STAC concept of Collections for improved organising and searching capabilities.
