HIGH ACCURACY DYNAMIC HIGHWAY MAPPING USING A GPS/INS/CCD SYSTEM WITH ON-THE-FLY GPS AMBIGUITY RESOLUTION

A high-precision land-based integrated mapping system was developed at the Ohio State University to support road centerline mapping operations at the Ohio Department of Transportation District 1 Office. The system represents a transition from the traditional mobile mapping paradigm towards a highly automated and autonomous design following the trends of modern geoinformatics. The two key components of the custom-designed system are a high-precision integrated GPS/INS navigation system and a fully digital and automated imaging subsystem. The van-based mapping system was designed to deliver the road centerline positions at sub-decimeter accuracy in a highly automated manner with limited human interaction in near real-time. The final report presents the system's concept and design, followed by a performance evaluation, including road test results, representing an operational environment, and then the operating instruction part closes the document.
