The Studio Platform load Cloud-Optimized GeoTIFFs (COG) by specifying URLs to standardized Spatio-Temporal Asset Catalog (STAC) metadata.

STAC metadata requirements

Studio provides tiling and metadata services but can work against external tiling services provided that they conform to standard STAC and tiling conventions.

  • The metadata file must be a valid STAC Item, version 1.0.0 or higher. STAC Collections and Catalogs are not currently supported.
  • Raster data referenced in STAC assets should be Cloud-Optimized GeoTIFFs and need to be publicly accessible via HTTPS.
  • STAC item must have Electro-Optical and Raster extensions, and at least one asset must have both eo:bands and raster:bands information. common_name must be provided in eo:bands and data_type must be provided in raster:bands.
