About SanGIS


The San Diego Geographic Information Source (SanGIS) is a Joint Powers Authority (JPA) of the City of San Diego and the County of San Diego responsible for maintaining a regional geographic information system (GIS) landbase and data warehouse. The JPA allows the City and the County to combine resources to meet common objectives to reduce duplication of efforts, maximize resources, provide for an efficient method of sharing information and provide timely updated data to the public.


The SanGIS mission is to maintain and promote the use of a regional geographic data warehouse for the San Diego region and to assist in the development of shared geographic data and automated systems which use that data.

SanGIS meets its mission statement through three primary functions:

Landbase Maintenance

The County and City geospatial landbase consists of over 17 data layers including lots, parcels, roads, addresses and open space easements. Additions, deletions, updates and corrections are made regularly to provide the most updated landbase possible.
