WebGIS is an Internet based technology that enables users to browse, query, and display spatial data using a standard web browser.

The ORNL DAAC WebGIS is 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 Web Map Service (WMS) and Web Coverage Service (WCS) OpenGIS protocols.
