The PO.DAAC is pleased to announce the release of the OPERA Dynamic Surface Water Extent from Harmonized Landsat Sentinel-2 provisional product (Version 1) Dataset. The input dataset for generating each product is the Harmonized Landsat-8 and Sentinel-2A/B (HLS) product version 2.0. HLS products provide surface reflectance (SR) data from the Operational Land Imager (OLI) aboard the Landsat 8 satellite and the MultiSpectral Instrument (MSI) aboard the Sentinel-2A/B satellite.
Each product is distributed as a set of 10 GeoTIFF (Geographic Tagged Image File Format) files including water classification, associated confidence, land cover classification, terrain shadow layer, cloud/cloud-shadow classification, Digital elevation model (DEM), and Diagnostic layer in PNG format.
Datasets included in this release are listed below with their digital object identifiers linked to the PO.DAAC Web Portal.
