Eksperimentering med pgstac for å katalogisere geospatiale filer i et S3-lager og gjøre dem søkbare via en STAC API, i stedet for en statisk JSON-katalog på S3. Fire containere: - db: Postgres 17 + PostGIS 3 + pgstac (lagrer hele katalogen) - api: stac-fastapi-pgstac (serverer collections/items med CORS) - viewer: STAC Browser + /s3 SigV4-proxy med MapLibre-preview for PMTiles - scanner: on-demand, scanner en S3-mappe og laster en Collection inn i pgstac Scanneren leser metadata billig (header/footer) for COG/GeoTIFF, GeoJSON, GeoParquet og PMTiles, bygger ett item per fil, og gjør upsert + prune slik at en collection speiler S3-mappa. En mappe = en Collection. README beskriver oppsett, .env-variabler, scan-flyt og metadata-felter, med skjermbilder og systemskisser.
