Geoprocessing Services and Web Applications from NASA Socioeconomic Data and Applications Center (SEDAC) Enable Data Access and Analysis
Abstract
The Socioeconomic Data and Applications Center (SEDAC) has developed numerous operational spatial data services aimed at providing online access, visualization, and analytic functions for GIS socioeconomic and environmental data. More than 200 data layers related to population, settlements, infrastructure, agriculture, environmental pollution, land use, health, hazards, climate change and other aspects of sustainable development are available through WMS, WFS, and/or WCS.
Two new high resolution data sets released through SEDAC map global, man-made impervious surfaces and urban extents in unprecedented detail. The Human Built-up and Settlement Extent (HBASE) and Global Man-made Impervious Surface (GMIS), are among the first global, 30-meter spatial resolution data sets of their kind that are derived from the 2010 Global Land Survey (GLS) free Landsat archive. Using the Data Visualization and Access Tool, users may view and download the GMIS and HBASE data sets by country, tile, shapefile, rectangle or polygon. Data are available at 30m, 250m, and 1km resolutions in either geographic or UTM projection. Users may also explore map layers from the GMIS and HBASE data sets, including the uncertainty layers, in a four-panel map view. Features include the ability to zoom in to the native data resolution of 30-meters; to query pixel values; to display a layer full-screen; and more (http://sedac.ciesin.columbia.edu/mapping/gmis-hbase/explore-view/). Version 3 of the SEDAC Population Estimation Service (PES) supports geoprocessing operations through WPS and REST services for estimating population totals, basic demographic characteristics (Age Pyramids), and related statistics within a user-defined region. It enables users of a wide variety of map clients and tools to quickly obtain estimates of the number of people residing in specific areas without having to download and analyze large amounts of spatial data. Detailed description of the services and link to a web application utilizing these services is available at http://sedac.ciesin.columbia.edu/data/collection/gpw-v4/population-estimation-service.- Publication:
