GIS


The SANDAG Geographic Information System (GIS) program is used to support a wide variety of planning applications, including demography, transportation, land use, environment, public safety, and public facility siting and management.

SANDAG has a well recognized and award winning Geographic Information System (GIS) program. Having used GIS technology since the early 1970s, we continue to pioneer innovative approaches to GIS database development, maintenance, analysis, and display. Our GIS is used to support a wide variety of planning applications, including demography, transportation, land use, environment, public safety, and public facility siting and management.

Through the San Diego Regional/GIS Council, we work cooperatively with our members and other agencies to share GIS expertise, information, applications, and databases. The Council has formed a number of subcommittees over the years to research new technologies in specific topical areas and share the results with other agencies in the region. The Council has created an e-mail list group where users can communicate with each other, share information, post questions to the GIS community, and broadcast announcements. We have taken the lead in forming partnerships to acquire and develop regionwide vector and digital imagery databases and to develop applications that are of use to many agencies. SANDAG makes many GIS layers available to the public and has instituted cooperative data sharing agreements with a number of federal, state, and local agencies.

In recent years we have worked collaboratively with the San Diego State University (SDSU) Department of Geography to research more effective ways to use remotely sensed imagery to update GIS databases, improve our visual map displays, and in using remotely sensed imagery for change detection in both urban and natural environments. SDSU has also helped us educate other agencies in the region on potential uses of various types of remotely sensed image products.

Our GIS is continually evolving to keep up with changing technologies. We have migrated to ArcGIS and use a sophisticated relational database management system to allow better integration of our geographic and non-geographic data systems. We also are expanding our databases and models to more effectively support interregional and binational planning efforts.
