Parking enforcement project with heading GPS

Today, many municipalities across the United States and in Canada, employ the autoChalk™ digital chalking and license plate recognition (LPR) system developed by Tannery Creek Systems Inc. Before autoChalk, parking enforcement meant manually chalking the tires of parked cars by law enforcement officials to see if the cars overstayed the meter — an expensive use of valuable law enforcement resources.
NavtechGPS was brought in on the developmental stages of this now popular parking enforcement system to outfit automated parking attendant vehicles with heading-based GPS receivers. The system used a two-antenna and two-GPS-receiver system to provide vehicle heading information even when standing still. The GPS position data was used to locate, then later relocate the subject vehicles by integrating the GPS data with a photographic video recognition system to catch violators.
