In August 2021, NASA released science quality Harmonized Landsat/Sentinel-2 (HLS) products for both cloud-based access and direct download from NASA's Land Processes Distributed Active Archive Center (LP DAAC). These 30-meter products, HLSS30 (Sentinel-2 component) and HLSL30 (Landsat component), are placed on the same grid and are generated and distributed fully in the cloud. Similarly, the European Space Agency (ESA) is prototyping Harmonized Landsat Sentinel-2 products at 10-meter resolution. NASA and ESA data production and science teams will present technical details on the data production system, data product status and availability, and the benefit of harmonizing instruments with similar sensing characteristics between the agencies.
The webinar is presented by the Earth Science Informatics Technical Committee (ESI TC), which is part of the IEEE Geoscience and Remote Sensing Society (GRSS). GRSS is a community of researchers and practitioners collaborating and designing tools to understand our interaction with Earth’s ecosystems, to monitor its environments, oceans and ice caps, and to characterize potential risks. The ESI TC provides a venue for informatics professionals to exchange ideas and share knowledge. It aims at advancing application of informatics to geosciences and remote sensing, assessing technology to support data stewardship and management, and promoting best practices and lessons learned.
