Sentinel 2 Cloud Free Temporal Mosaics

This repository holds a large (and growing!) collection of cloudless Senitnel 2 data. All bands (except B10 as this was generated from L2A) are available at their original native resolution.

This data is licensed under the creative commons 4.0 international license which, in summary, only requires attribution.

Resources

• Earth Genome STAC instance for searching this collection
• STAC Browser, human friendly interface
• Tile Cache, levels 0-8 (2.5gb) - if you wanted to set up a tile server, this archive has tile levels 0-8 pre-tiled.

Naming

Artifacts are name accoring to their original UTM grid number, concatonated with the start and end dates. For example 31TDF_2023-01-01_2024-01-01 will give you Barcelona (31TDF) over the course of 2023.

Artifacts and Metadata

All assets are COG encoded GeoTiffs in Web Mercator (EPSG:3857) projection. Besides the item id itself, the STAC catalog has the original UTM infornmation so you can calculate and then reproject to the original EPSG code, if needed.

The STAC assets also have 2 properties to help better understand the provience and quality of the images:

• good_pxl_pct is a the estimated percentage of "good" (non masked) pixels
• generated_from is an array of references to the Sentinel L2A assets which contributed to this asset
