Geographic Information Systems (GIS)

A Geographic Information System (GIS) is a computer-based tool used to map and analyze features and occurrences. GIS technology integrates common database operations such as query and statistical analysis with the unique visualization and geographic analysis benefits offered by maps. These abilities distinguish GIS from other information systems and make it valuable to a wide range of public and private enterprises for explaining occurrences, predicting outcomes, and planning strategies.

GIS Within the City of Temecula

The City of Temecula’s GIS Map Viewer is a tool utilized by public and City departments. It assists decision makers and staff in making informed decisions regarding the health and safety of the residents of Temecula and how to improve their quality of life.


The City’s Map Viewer provides the user with access to approximately 70 of the City’s GIS data layers. Map Viewer allows the user to locate an area or a specific property by searching for an Assessor Parcel Number (APN), address, street intersection, tract map number or name, and by latitude/longitude coordinate. The user can also locate specific parks, public buildings, points of interest, and public safety facilities.

Map Viewer provides the user the ability to see, query and create maps utilizing a number of different layers of information including fault zones, flood plains, high fire zones, environmentally sensitive areas, and land use and zoning to name a few. Map Viewer also provides the user the ability to identify properties within a specific radius of a user designated parcel or area. This can be used to prepare a list or mailing labels with the addresses of affected property owners.


The data used in Map Viewer is from the City of Temecula GIS and is derived from base data produced by the Riverside County Assessor's Department and the Transportation and Land Management Agency of Riverside County. The City of Temecula assumes no warranty or legal responsibility for this information. Data and information represented here is subject to update and modification. The aerial and topographic data should not be used for the purpose of surveying or locating property lines. To accurately determine property boundaries, a licensed land surveyor should be consulted.
