Redefining the Paradigm of Moderm Mobile Mapping: An Automated High-Precision Road Centerline Mapping System.

A high-precision land-based integrated mapping system has been 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 subdecimeter accuracy in a highly automated manner with limited human interaction in near real time. The paper presents the system's concept and design, followed by an individual performance evaluation of the navigation and imaging components; and finally road test results, representing an operational environment, are also reported.
