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 ArcGIS Server and Open Source Mapserver technology. The user interface has been built with ArcGIS Javascript API along with the Open Source Dojo Toolkit. The ORNL DAAC WebGIS integrates data resources published from ArcGIS services and Open Geospatial Consortium (OGC) Web Map Services (WMS).


Data Access

The ORNL DAAC WebGIS includes a number of land cover, biophysical, elevation, and geopolitical layers, as well as access to other relevant OGC map layers. Users can interrogate map features and extract and download selected map features information in Comma Separated Value (CSV) format.
