The Washington Suburban Sanitary Commission (WSSC) recently completed a cooperative pilot project with Montgomery and Prince George's counties, Md., in which a complete 59-layer geographic information system (GIS) database was developed for a portion of its service area. During the pilot project described in this article, planimetric and parcel data were developed, and water and sewer facility maps were digitized. The procedures and approach defined during the pilot project will be used to develop a full-scale database. This article describes and evaluates the design process, the conversion methods, and the applications developed. Includes tables.
