Samenvatting
The California Photolog System is a sequential file of 35 mm color pictures showing the highway from the driver's vantage point. Across the top of each picture is a 15-digit binary coded decimal number which indicates the date photographed and the location within the highway system. Typical uses include gathering of accident information and inventory data for updating computer files, determining scenic highways and roadside rest areas, court cases, determining sign messages and reviewing accident locations.
