NASA’s Physical Oceanography Distributed Active Archive Center (PO.DAAC) released the Observational Products for End-Users from Remote Sensing Analysis (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 Earthdata catalog.
