A brief video introduction to data sets Human Built-up and Settlement Extent (HBASE) and Global Man-made Impervious Surface (GMIS) + how to use the mapping tool to visualizing 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 cyberseminar held February 20–27, 2018, looked at key future directions for the integration of remote sensing into social science research, building on the groundbreaking “People and Pixels” volume produced by the National Research Council in 1998. It was organized by the Population-Environment Research Network (PERN), which is hosted by SEDAC and sponsored by the International Union for the Scientific Study of Population and Future Earth.

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. New features of GPWv4 include more recent census data; a smaller grid size; and many more input census units.

Results of a NASA-funded pilot study to develop satellite-derived indicators in three issues areas—ambient air pollution, coastal eutrophication, and biomass burning—are presented, in the context of what makes an indicator that passes muster with policy and technical audiences, and the underlying satellite data and methodologies. Part of the monthly NASA Earthdata Webinar Series that highlights NASA EOSDIS data products and data access tools.

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.

A simple, online tool for estimating the population living in proximity to hazardous events as well as human settlements and major facilities such as dams and nuclear power plants. The Hazards Mapper displays near-real-time data on earthquakes, fires, air quality, and, for the U.S., flood and tornado warnings. Part of the monthly NASA Earthdata Webinar Series that highlights NASA EOSDIS data products and data access tools.

Gridded Population of the World (GPW) is a global, high-resolution population data collection produced by the NASA Socioeconomic Data and Applications Center (SEDAC). Part of the monthly NASA Earthdata Webinar series that showcases NASA EOSDIS data products and data access tools, this Webinar focuses on the development of GPW, improvements to this fourth version, research and policy applications, and methods. Also available via Adobe Connect.
