The original GeoTIFF files used to create the Sentinel-2 cloudless layer are now available on an AWS S3 bucket. The bucket uses the “requester pays” setting which means you need to access it using your AWS credentials.
Tiles are stored as GeoTIFFs containing three 8 bits bands (red, green, blue) each in a non-projected geographic coordinate system (WGS84, EPSG 4326). Compression used is LZW (lossless), tile shape is 512×512 pixels.
Tiles are structured in a tile pyramid scheme based on the WMTS-simple profile defined by the OGC.
To optimize tile numbers, they are combined into 2×2 bigger tiles (metatiles), hence the usual WMTS tile indices (zoom, column, row) don’t apply exactly. To identify the correct tiles per zoom level, one must use the columns and row identifier from the zoom level above (z-1).
This means, URLs to the tiles are following the schema:
Zoom levels available are 7 to 13, where 13 best resembles the original resolution (10 m).
