Terraviva resource

A tool for visualization of socio-economic data, the 2008 TerraViva! SEDAC Viewer has been updated with a wide range of new SEDAC data. This map viewer and standalone software application (Microsoft Windows-based) uses a data-viewing engine and tools to enable visualization and integration of hundreds of socioeconomic and environmental variables and layers, including a range of satellite-based data. The update encompasses 51 ready-made maps, ten GeoData indicator collections with hundreds of variables, and other features—scatter plots, tabular data display, map image production, and Web-based download of additional data layers.

Produced in collaboration between ISciences and the NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN, these data sets build on a collection that includes the flagship SEDAC data set, Gridded Population of the World (GPW), and others. The 2008 version adds the following SEDAC data collections: • The Human Appropriation of Net Primary Productivity (HANPP)Natural Disaster Hotspots: A Global Risk AnalysisGlobal Poverty MappingThe Human Footprint and Last of the Wild, version twoThe Population, Landscape, and Climate Estimates (PLACE II)The Compendium of Environmental Sustainability Indicators.

The software is free of charge and available on CD.
