STAC (SpatioTemporal Asset Catalog) is not a data format but an open JSON schema for describing geo assets: satellite imagery, rasters, vector layers. The Catalog -> Collection -> Item -> Asset hierarchy plus the STAC API REST spec made STAC the de-facto standard for cloud catalogs (AWS, Microsoft Planetary Computer, ESA Copernicus). Our exporter generates a SINGLE STAC Item v1.0 — a JSON document describing the exported area: bbox, GeoJSON frame geometry, export datetime, per-layer statistics, and asset links. It is a "brick" you drop into your own catalog. To be clear: the Item's asset links are template hrefs to your export, not embedded data, and this is an Item rather than a full Catalog/Collection hierarchy.
