DIGITAL IMAGE BASED PHOTOLOG SYSTEM

This paper describes how the County of Ventura Transportation Department recently (in early 2004) acquired a field data collection system to better manage historical, current and future changes to the road network. The objective of this system was to provide an efficient method of building "point-in-time" references to the County's road network that includes compressed digital imagery of signs; markings, signals and all appurtenances on the roadway surface of the County-owned roadway system. The Department has previously logged 35mm color film reels of the roadways at 3- and 4-year intervals between 1980 and 1994 using in-house staff and its own distance measure instrument (DMI). A combination the DMI breaking down and the retirement of the staff person in charge of the analogue system triggered a decision to switch to a digital image based system. This paper and the associated presentation will discuss how the project scope was developed, selection of the most appropriate vendor and lessons learned. Information will be shared about how the Department uses this digital image library in its day-to-day operations.
