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

This article describes the high-precision land-based integrated mapping system that was developed at The Ohio State University to support road centerline mapping operations at the Ohio Department of Transportation District 1 Office. The two key components of the custom-designed system are a high-precision integrated global positioning system and inertial navigation system (GPS/INS) 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 and in near real time. The authors present the system's concept and design, followed by an individual performance evaluation of the navigation and imaging components; and finally road test results (in and around the OSU campus) representing an operational environment, are also reported. The authors conclude that the tightly coupled GPS/INS navigation system has shown excellent performance under good to moderate GPS signal reception. They briefly discuss strategies to incorporate when GPS signals are weak or lost.
