GIS Mission Statement

To plan and implement an enterprise supported distributed Geographic Information System (GIS) through collaborative partnerships between the GIS Division and all other City departments.


History and Purpose

The GIS Division was created on July 1, 2000 under the Office of the City Manager. The Division grew out of the need to take the digital map data that had been under development by various City departments since 1990, and move it to the next level. This was accomplished by first adding intelligence to the mapping data by connecting the digital maps to databases that contain information about the features on each map. The Division next introduced a web site, available to all City staff, that allowed them access to the City's entire geographic library. This was a major step in achieving one of the Division's primary goals, to facilitate better decision making city-wide by providing easy access to the City's geographic resources. The GIS Division is now pleased to provide this same information to the public through the City's public GIS web applications. We in the GIS Division hope you will find these web apps informative and useful, and welcome any feedback you might have on the system
