This brief video introduction introduces users to the companion data sets Human Built-up and Settlement Extent (HBASE) and Global Man-made Impervious Surface (GMIS), and demonstrates how to use the mapping tool to visualize the data. HBASE and GMIS were produced as a result of a collaboration between the NASA Goddard Space Flight Center and the Department of Geographical Sciences at the University of Maryland, funded through the NASA Land Cover Land Use Change Program.
This brief video is an introduction to the most recent update to the NASA SEDAC flagship gridded data product, Gridded Population of the World (GPW), which models the global distribution of human population on a continuous surface.
