The San Bernardino County, Geographic Information Management System (GIMS) has developed a county wide Street Network basemap. The Street Network is a digital basemap containing streets, rail roads and stream courses. This basemap is composed of map features (streets, rail roads & streams) and a database containing information about the map features. The database contains such information as street name, street address range and city. The Street Network has been developed from a variety of data sources including the USGS 7.5' quad sheets, subdivision tract maps, parcel maps & aerial photography.

Positional accuracy within urbanized areas can range from + 2 - 20 feet. Non-subdivided rural areas are generally within +- 30 ft with aerial photography being alignment source.

The Street Network employs a single line representation of street centerlines. The Street Network fully supports address-matching applications.

The Street Network is continuously maintained and upgraded. New streets are added from subdivsion tract and parcel maps as they are recorded with County Recorder's Office
