Maps & Geographic Information
Geographic Information System
A Geographic Information System (GIS) is a computer system that captures, stores, checks, integrates, manipulates, analyzes and displays data related to a position on the Earth's surface. GIS is often used to create Maps, but can also be much more.
Hidden in most data is a geographical component: an address, postal code, census block, city, county, or latitude/longitude coordinate. For City GIS data, please see the Data Download page.
GIS can use this information to find the geographical relationships such as which services or facilities are near a particular address. The Interactive Maps and Tools page links to dynamic interactive maps and address lookup tools.
The City Map Gallery is a collection of ready-to-print maps as well as links to various City departments' maps. There are many maps available such as Council District, Neighborhood, Historic, Park, and Land-use maps.
How are Geographic Information Systems used at the City?
GIS is an enabling technology that is used to facilitate a variety of business functions in the City. Below are just a few examples:
Public Safety 911
Garbage Truck Routing
Subdivision Plan Submission
General Plan Update
