Geographic Information Systems (GIS)
GIS Day - November 17th, 2021
Over 20 years ago, Jack Dangermond, the founder and president of Esri, envisioned people collaborating and sharing how GIS affects everyone. This led to the establishment of GIS Day, which was first observed in 1999. The explosion of geospatial technology since then has expanded that idea into a global event that shows how geography and the real-world applications of GIS are making a difference in business, government and society. It's a chance for organizations to share their accomplishments and inspire others to discover and use GIS.
The City of Temecula staff uses GIS daily, and the orange button below gives everyone access to the City's maps and data, whenever and wherever you are.
To celebrate GIS Day, please enjoy these videos provided by Esri, the global market leader in geographic information system (GIS) software, location intelligence, and mapping.

What is 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.

The City of Temecula's Map Viewer provides the user with access to approximately 70 of the City’s GIS data layers. The City of Temecula 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.
The 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.
For information, comments or you wish to report an inaccuracy or inconsistency with any of the map layers, please contact the GIS Department by phone at 951-308-6300, or email the GIS Department.
