Seattle City Light understood that it could transform field operations if it could provide open access to the distribution system data housed in its CAD database. Ideally, Seattle City Light wanted all personnel and field crews to be able to access and query data in the field, at any work site. The solution would need to work for personnel with no CAD expertise, specialized software or proprietary hardware. It would need to be available from any location, even offline when the user was unable to access any network. Seattle City Light evaluated available technologies and selected TerraGo's GeoPDF(r) to achieve this vision.
