The use of automated mapping/facilities management, geographic information systems (GIS), and computer aided design-drafting (CAD) technology within the water industry was surveyed by the AWWA Computer Assisted Design Committee. Of the 270 respondents, only 20 percent indicated that they had no involvement in computerization in these areas. In addition to standard applications such as engineering drafting and facilities mapping, utilities are using raster data for document imaging and integration of raster and vectorized data and developing interfaces between GIS and other systems such as supervisory control and data acquisition, customer billing, and hydraulic models. The most common approach to GIS data base development is photogrammetric compilation of a base map and digitizing locations of facilities, although there is strong interest and some activity in scanning and vectorizing existing maps of facilities. Includes tables.
