Harmonized Landsat Sentinel-2
Satellite imagery from the Landsat 8 and Sentinel-2 satellites, aligned to a common grid and processed to compatible color spaces.
The Harmonized Landsat Sentinel-2 (HLS) product includes data from the Landsat-8 and Sentinel-2 satellites, aligned to a common tiling system at 30m resolution, from 2013 to the present for Landsat and 2015 to the present for Sentinel-2. HLS is administered by the National Aeronautics and Space Administration (NASA).
This dataset is maintained by Ag-Analytics®. Ag-Analytics® also provides an API which accepts an area of interest (AOI) polygon, date range, and other options, and returns processed images for individual MSI bands as well as Normalized Difference Vegetation Index and other metrics, as well as cloud-filtered mosaics.
This dataset is updated weekly.
Data are stored as cloud-optimized GeoTIFF files in the East US 2 data center, in the following blob container:
Within that container, data are organized according to:
tileidis a four-character tile code from the Sentinel-2 tiling system
daynumis a four-digit year plus a three-digit day of year (from 001 to 365), e.g. 2019001 represents January 1, 2019
subdatasetis a two-character, 1-indexed string indicating a subdataset (see below)
A mapping from lat/lon to tile IDs can be found here; the notebook provided under “data access” demonstrates the use of this table to look up a tile ID by lat/lon. Tile IDs can also be found using the Ag-Analytics® API.
Data are provided for the United States, northern Mexico, southern Canada, France, Ireland, Germany, Ukraine, South Africa, and southeastern Australia; see the HLS coverage map for coverage areas.
Bands are as follows:
|Band name||OLI band number||MSI band number||L30 subdatasetnumber||S30 subdatasetnumber|
|Thermal infrared 1||10||09|
|Thermal infrared 2||11||10|
For example the following filename, HLS.S30.T16TDL.2019206.v1.4_01.tif would be located at https://hlssa.blob.core.windows.net/hls/S30/HLS.S30.T16TDL.2019206.v1.4_03.tif and would represent Sentinel-2 (S30) HLS data for tile 16TDL (primary tile 16T, sub-tile DL) for dataset band 03 (MSI Band 3, Green) for the 206th day of 2019.
We also provide a read-only SAS (shared access signature) token to allow access to HLS data via, e.g., BlobFuse, which allows you to mount blob containers as drives:
Mounting instructions for Linux are here.
HLS data can consume hundreds of terabytes, so large-scale processing is best performed in the East US 2 Azure data center where the images are stored. If you are using HLS data for environmental science applications, consider applying for an AI for Earth grant to support your compute requirements.
