The Office of the Chief Technology Officer's GIS program now leverages the ESRI's online resource center. Power GIS users can now open the DC Atlas All-in-One service directly within an ArcGIS Desktop session. Currently, the DC Atlas All-in-One service provides detailed maps with GIS functionality served up within ArcIMS, a web based application from the Environmental Systems Research Institute (ESRI).
