AB: WebGIS is an Internet based technology that enables users to browse, query, and distribute spatial data using a standard web browser. It is an effective tool for providing users access to different types of geospatial data from within a web environment. The ORNL DAAC's WebGIS system is one such WebGIS system that utilizes web technology to enable users to visualize datasets relevant to biogeochemical dynamics. The ORNL DAAC's WebGIS is based on ESRI's ArcIMS and ArcSDE technology. Open Source technologies such as Minnesota Mapserver and Geospatial Data Abstraction Library (GDAL) are also used in this WebGIS instance. Users can perform basic GIS operations from within a web environment and also download relevant datasets for their region of interest. ORNL DAAC's WebGIS provides user access to a number of landcover, biophysical, elevation, geopolitical and Open Geospatial Consortium (OGC) layers. Region specific datasets such as North American Carbon Program (NACP) datasets and global coverage datasets 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 instance.
