The ORNL DAAC has developed a WebGIS system that consolidates earlier project-centric viewers into one system to help users locate data, including site characteristics, from flux tower sites, MODIS ASCII Subset Sites, and NPP field sites from around the world.
WebGIS is an internet-based technology that enables users to browse, query, display, and download spatial data using a standard web browser. The ORNL DAAC WebGIS includes a number of land cover, biophysical, elevation, and geopolitical layers, as well as access to other relevant Open Geospatial Consortium (OGC) layers. Users can interrogate map features and extract and download selected map features including map layers (shape files).
The services provided by the ORNL DAAC WebGIS are based on ESRI ArcIMS and Minnesota Mapserver technology. The user interface has been built with ArcIMS while some of the tools have been implemented using Minnesota Mapserver. The ORNL DAAC WebGIS supports OGC Web Map Service (WMS) and Web Coverage Service (WCS) protocols, allowing other organizations to incorporate our data layers in their on-line applications.
