WebGIS is an Internet based technology that enables users to browse, query, and download spatial data using a standard web browser. It is an effective tool to disseminate different types of geospatial data to users through a web environment. The ORNL DAAC’s WebGIS system enables users to visualize data sets relevant to biogeochemical dynamics and create custom data sets to meet their individual disciplinary needs. The ORNL DAAC’s WebGIS is based primarily on ESRI’s ArcIMS and ArcSDE technologies. Open Source technologies such as the Minnesota Mapserver, and Geospatial Data Abstraction Library (GDAL) are also incorporated. Users can perform basic GIS operations from within a web environment to create and download custom regional data sets relevant to their individual research needs. ORNL DAAC’s WebGIS provides user access to a number of landcover, biophysical, elevation, geopolitical and Open Geospatial Consortium (OGC) layers. Region specific data sets such as the North American Carbon Program (NACP) data sets and global coverage data sets are distributed through the WebGIS. The ORNL DAAC’s WebGIS also provides visualization and download of MODIS land product subsets for selected field sites. OGC standards such as Web Map Service (WMS) and Web Coverage Service (WCS) are supported within the ORNL DAAC’s WebGIS.
