Robert Kimball & Associates <br />in 1984 to conduct remapping of all of Orange County, the vendor <br />proposed a cost of $38,000 to provide a digitized centerline for <br />Orange County roads. The County decided at that time not to <br />purchase that product, and that staff would digitize centerlines <br />when the remapping project is completed. When the County <br />decided to obtain a E911 /GIS /CAD integrated system, plans were <br />to begin the system's graphic (map) capabilities with a s were <br />line file obtained from existing data sources (the US Census <br />Bureau TIGER File or the TIMS Bus Routing File for Orange <br />County). Funds were set aside to have a local consultant learn <br />how to build this file with GIS software, after the <br />implementation of E911, as part of tieing down individual <br />addresses to the ground. The file would be used only until the <br />highly accurate Kimball maps were received, and then would be <br />deleted because of its relative lack of accuracy. <br />�1i <br />
