Most utilities throughout the United States and abroad are planning or implementing an automated mapping-facilities management-geographic information system. The database acquisition and conversion process is typically the most expensive and time-consuming part of implementing such a system. Many agencies convert water or sewer facility data immediately after a land and parcel database is developed. This article highlights the key technical issues associated with creating a geographic information system database to support water utility operations and applications. It describes database concepts and provides an overview of the data conversion process. Alternative approaches for developing a base map and converting water facility data are described, and technical issues relating to accuracy, symbology, feature content, conversion methodologies, and quality control are discussed. Includes tables, figures.
