NASA EarthData Webinar—Gridded Population and Settlement Data for Human Dimensions Research

cartoon abstraction shows young woman and young man literally interacting with data

An introduction to the growing diversity of gridded data and overview of approaches, including those that utilize new sources of remote sensing data, and an introduction to the SEDAC POPGRID Viewer, which lets users easily compare data products for their specific regions of interest; under the auspices of the POPGRID Data Collaborative. Part of NASA′s EarthData Webinar Series.

GMIS and HBASE: Data Products from NASA SEDAC

GMIS and HBASE: Data Products from NASA SEDAC

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.

Webinar: Crowdsourcing Data and Quality Control–The Experience of OpenStreetMap

Webinar #8: Crowdsourcing Data and Quality Control–The Experience of OpenStreetMap

SEDAC has led a global effort under ICSU CODATA's Global Roads Data Development Task Group. The SEDAC Global Roads Open Access Data Set (gROADS) version 1 is one outcome. In preparation for gROADSv2, SEDAC has led an effort to validate the data contributed by some two million volunteers through OpenStreetMap. This Webinar explores the outcome.
