SanGIS was created in July, 1997, as a Joint Powers Agreement (JPA)
between the City and County of San Diego. After 13 years of working
together on data and application development, the City and County
decided to formalize their partnership in GIS by creating the SanGIS
JPA. Finding that access to correct and current geographic data was
considered more important than application development to County and
City departments, SanGIS focuses on ensuring geographic data is
maintained and accessible.
To maintain and promote the use of a regional geographic data
warehouse for the San Diego area and to facilitate the development of
shared geographic data and automated systems which use that data.
1. To ensure geographic data currency and integrity.
2. To provide cost effective access to geographic data to member
agencies, subscribers and the public.
3. To generate revenue from the sale of geographic data products to
reduce the cost of map maintenance to member agencies.
SanGIS data was created or obtained from several sources. Some of our
data is licensed; some data was created from tabular digital files;
some data was digitized from paper maps; and other data was entered
using coordinate geometry tools.
Updating the Data:
Responsibility for the maintenance of the over 200 geographic data
layers is distributed to City and County departments based on several
factors such as who has the source documents, who has the greatest
need for the data, and who is held accountable for this data as part
of their city-wide or county-wide duties. Most basemap maintenance is
completed by SanGIS staff. SanGIS is also responsible for coordinating
with other data maintainers to ensure currency and accuracy for all
All of the SanGIS geographic data is within San Diego County
only. Much of our data covers the entire County of San Diego but some
is only for the City of San Diego.

these maps. Neither SanGIS nor the SanGIS participants assume any

The accuracy of the data varies between themes and within themes
depending on the source documents used to create the data. Most of the
source documents used for SanGIS data was at one inch equals 200 feet
or one inch equals 400 feet, making it more accurate than many other
GIS data sources. In general, the SanGIS data has an overall accuracy
of plus or minus 10 feet.
Viewing maps requires no special software. Downloading and viewing|
of data requires ESRI's ArcExplorer Software or ArcView.
