New Dataset Released by NASA SEDAC

New Dataset Released by NASA SEDAC

The NASA Socioeconomic Data and Applications Center (SEDAC; WDS Regular Member), operated by the Center for International Earth Science Information Network (CIESIN) has released a new dataset. The 2015 Urban Extents from VIIRS and MODIS for the Continental U.S. Using Machine Learning Methods is a highly accurate urban settlement layer at a resolution of 500 m, using 2015 satellite data and machine learning methods. The new dataset and project work are discussed in a recent article.

Another article highlights the third iteration (v3) of SEDAC's Low Elevation Coastal Zones (LECZ) dataset and its contribution to a new report by Coalition for Urban Transitions, which examines the increased threat to urban coastal areas from sea-level rise. Currently under development, LECZv3 builds on the first global estimates of impacts to urban populations from sea-level rise presented in a 2007 paper by a team from CIESIN and the International Institute for Environment and Development.

SEDAC Deputy Manager and Vice-chair of the WDS Scientific Committee, Alex de Sherbinin, is a contributing author to Chapter Two: High Mountain Areas in the new Intergovernmental Panel on Climate Change Special Report on the Ocean and Cryosphere.
