Global Environmental Change - January 15, 2016 Changing Global Patterns of Urban Exposure to Flood and Drought Hazards
Data Use - Visualizing the Extent of Cropland and Pastures
Food: An Atlas – June 11, 2014 The cropland and pasture data distributed by SEDAC are presented as cartograms, in which land area is replaced by extent of crops and pastures, to better visualize the global distribution and production of food around the world.
Data Use - Population and Burned Areas Around the Globe
PLoS ONE – February 7, 2014 Research based on data from SEDAC’s Gridded Population of the World collection and burned area maps based on NASA’s MODIS satellite observations is helping to untangle the complex relationship between population density, land use and fire.
Map Gallery - Population Dynamics
Global Estimated Net Migration by Decade: 1970-2000 A map collection featuring global net migration (balance between in-migration and out-migration) for the decades of the 1970s, 1980s, and 1990s.
Map Gallery - Land Use Land Cover
Global Grid of Probabilities of Urban Expansion to 2030 A map collection featuring spatially explicit probabilistic forecasts of global urban land cover change from 2000 to 2030.
Map Gallery - Urban Spatial Data
Dar es Salaam Land Use and Informal Settlement Data Set A map collection featuring the change in land use for Dar es Salaam, Tanzania, considered one of the most dynamic urban centers in Africa.
Tools and Apps - SEDAC Hazards Mapper
The SEDAC Hazards Mapper allows users to estimate the populations in proximity to natural disasters, and to assess exposure. Map layers are available from various sources including SEDAC, NASA, USGS, NOAA, ESRI, and others.
Tools and Apps - Population Estimation Service (PES)
The Population Estimation Service is a Web-based service for estimating population totals and related statistics within a user-defined region. The service is accessible through three standard protocols: OGC-WPS, ArcGIS-REST and ArcGIS-SOAP.
Tools and Apps - SEDAC Map Viewer
The SEDAC Map Viewer is a Web mapping tool for visualizing all SEDAC map layers. The viewer organizes the layers into 14 interdisciplinary topics (themes) that can be selected by users.
Theme - Agriculture and Food Security
Find data sets, maps, map services, featured uses of data and other resources related to Agriculture and Food Security.
Theme - Infrastructure
Find data sets, maps, map services, featured uses of data and other resources related to Infrastructure.
Theme - Poverty and Economic Indicators
Find data sets, maps, map services, featured uses of data and other resources related to Poverty and Economic Indicators.
Resource - Surveying User Satisfaction
Alex de Sherbinin, CIESIN associate director for science applications and a member of the WDS Scientific Committee, describes how the American Customer Satisfaction Index (ACSI) survey is an important performance metric for NASA.
Resource - Crowdsourcing Data and Quality Control
SEDAC has led an effort to validate data contributed by some two million volunteers through OpenStreetMap in preparation for the Global Roads Open Access Data Set (gROADS) version 2.
Resource - Rapid Assessment of Hazards
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.
