  1. National Aeronautics and Space Administration ORNL DAAC Spatial Data Access Tool (SDAT): Internet tools to access and visualize land-based data www.nasa.gov

  2. What is SDAT • Web-based tool that enables users to browse, visualize and download geospatial data in various user selected spatial/temporal extents, formats, and projections • Data include selected ORNL DAAC Archived Data Sets as well as other biogeochemical dynamics related data (Land Cover, Elevation, Climate Classification, Ecoregions, and Soils). Tammy Walker Beaty

  3. About SDAT • Provides access to various geospatial data through Open Geospatial Consortium (OGC) standards-based Web Services • Web Map Service v1.1.1 • Web Coverage Service v1.0.0 • Two levels of tool features • Data Set Level • Data File (granule) Level Tammy Walker Beaty

  4. SDAT Landing page – Data Set Level Functions, interface to Granule Level Functions • http://webmap.ornl.gov/wcsdown/ • Visualize Data Set – automatic function • Visualize in Google Earth • View Metadata • Proceed to file/granule level download options • Projection • Resolution • Format • Time • Bands • Interpolation Method • Spatial Extent Tammy Walker Beaty
