Service Description: Road centerlines are captured from the aerial photography as the apparent centerline. Attributes originally compiled via a conflation process from the original street centerline data to the new centerline coverage captured from the aerial photography. Subsequently an extensive QC process followed to correct errors in the conflation process. These areas were identified by staff in phase one of the QC process.

Subject: This vew specifcally shows only the State and Federal Highways in Sonoma County.
The purpose of the capture of street centerlines from the orthophotography was to improve the accuracy and completeness of the County of Sonoma's existing street centerline data. This included the spatial and attribute components of the street centerline data. The street centerlines are maintained to provide current address information for the Sonoma County Law Enforcement Consortium's CAD/911 Dispatch System. The data contain street address attributes such as, street name, street type, address ranges, and community code. Attributes are maintained with updates from the Permits & Resource Management Department and from notifications provided by the various cities. Attribute updates are a work in progress and the County does not guarantee 100% accuracy of all street attributes.
