Add support for STAC Item, Collection, Catalog web-map-links #7704

Description

@jo-chemla

It would be great if TerriaMap Catalogs could support Spatio-Temporal Assets Catalogs, STAC as either Catalog Groups or References. The STAC spec can encode either:

  • Item, Collection, Catalog - served via static JSON files or dynamic endpoints like from stac-utils/pgstac
  • as well as STAC API, less frequent, but represent a queriable search endpoint with POST payload filtering query.

What would probably fall into the scope of TerriaMap would be supporting the stac-extensions/web-map-links extension which can store catalogs/collections/items which point to endpoints for OGC 3D Tiles, WMS, WMTS, PMTiles, TileJSON, XYZ/TMS. It might be useful to see STAC-Browser (live here)

Note this feature request is different from exposing a standard STAC endpoint for an existing Terria Catalog - see discussion #6976 - which could help downstream integration of TerriaMap Catalogs into consuming applications and frontends like Qgis, STAC-Browser, Felt etc.

Similar discussion thread over here qgis/QGIS#36391 (comment)

Edit: another interesting topic I recently discovered is STAC federated-collection-discovery, see discussion here developmentseed/federated-collection-discovery#109 (comment) that might look like TerriaMap Catalogs + leaflet/cesium map, if combined with STAC-Browser (which now supports additional web-map-links in 4.0.0-rc1 extension see radiantearth/stac-browser#666 and more formats, especially 3d, see eg radiantearth/stac-browser#352)
