To systematically begin meeting infrastructure management challenges, the City of New York has dedicated precious resources to implement a utility-based Geographic Information System (GIS). In the mid-1980's, the City's Department of Environmental Protection (DEP) selected URS Consultants, Inc. to develop its first computer-assisted mapping techniques, a database collection methodology, and comprehensive, computer-based, sewer system maps for a heavily populated area in the Borough of Queens. Last year, DEP again awarded a contract to URS to digitally compile over 6,000 miles of water mains (and associated attribute data) located throughout all five boroughs of New York City. The purpose of this project is to provide an automated mapping system to update all records and develop a database for planning, design and operations/maintenance activities. This presentation will offer an overview of the GIS methodologies employed in both projects; outline criteria for planning, selecting, and using GIS technology; and, describe current GIS production procedures and challenges.
