The ORNL DAAC Spatial Data Access tool (SDAT) is an Open Geospatial Consortium (OGC) standards-based Web application to visualize and download spatial data in various user-selected spatial/temporal extents, file formats, and projections. Several data sets including land cover, biophysical properties, elevation, and selected ORNL DAAC archived data are available through SDAT. KMZ files are also provided for data visualization in Google Earth.

SDAT provides a Web-based user interface. It includes 3 categories of web pages:
  1. Main Page: provides a list of all the available data sets, their preview images, a keywords search box, and links to metadata pages and KMZ files.
  2. Data Set Page: lists all the available data granules (or files) contained in a data set, along with their preview images and brief spatial and temporal metadata.
  3. Data Granule Page: provides rich file-level metadata information on the top, OpenLayers-based interactive map widget in the middle, and WCS-based options for on-demand data access on the bottom.

• Introduction to SDAT User Interface ...

The Open Geospatial Consortium (OGC) specifications serve to standardize geospatial information from difference aspects, including representation, management, monitoring, processing, and application.

• Introduction to OGC Standards ...

The visualization and download capacilities provided by SDAT are based on ORNL DAAC OGC services. The ORNL DAAC OGC services were developed on MapServer . The OGC services include Web Coverage Service (WCS) v1.0.0 and Web Map Service (WMS) v1.1.1.
