Telecom technicians need to know the exact shape of each room and the precise position of each network jack. However, in the past they have not wanted to be burdened with also updating the GIS files. Now, when they move a jack in the real world, they can update the database by simply clicking and dragging a symbol for the jack in ArcGIS on a wireless laptop or tablet computer, Kato told me. Using ArcReader they can pan and zoom in a browser and using an ArcReader plug-in they can also drill down to nonspatial data that the system retrieves from a database maintained by Network Services. This office, which is a division of the university's Computing Center, and the university's Department of Telecom Services are separate operations but the Lab has patched their systems together.
