Streamline access and analysis of OPERA surface water extent with GIS services while avoiding downloading and managing data locally.

NASA’s Physical Oceanography Distributed Active Archive Center (PO.DAAC) announced the availability of the NASA Earthdata GIS (EGIS) image service for the OPERA Dynamic Surface Water Extent from Harmonized Landsat Sentinel-2 product (Version 1) collection—namely for the B01_WTR and B03_CONF layers.

These OPERA Dynamic Surface Water Extent (DSWx) services allow you to access, visualize, and analyze OPERA DSWx Harmonized Landsat and Sentinel-2 (HLS) data through your GIS software of choice without the need to download.

The following services are available as both ArcGIS REST image service endpoints, as well as Open Geospatial Consortium (OGC) endpoints.
