Our Mission

The GIS Division, within the Information Technology Services Department, provides broad access to geospatial data and applications throughout the City and to the public.

We strive to increase operating efficiency by:

  • Providing a common infrastructure on which to quickly and cost-effectively build and deploy GIS solutions,
  • Providing geospatial capabilities to non-GIS customers, and
  • Improving enterprise system capabilities by leveraging the value of geographic information.

What is GIS?

A geospatial information system (GIS) integrates hardware, software, data, and workflows to capture, manage, analyze, and display all forms of spatially referenced information.
