This paper is a case study in the utilization of COGO and GIS software for the Route 58 Corridor Development Program in Southwest Virginia. The planning effort included the evaluation of engineering feasibility, economic development projections, regional travel demand characteristics and impacts to a number of environmental resources such as wetlands, threatened and endangered species and pristine trout streams. The study window consists of portions of 12 counties in Virginia, 5 counties in Tennessee and 5 counties in North Carolina. Over 600 miles of alignment alternatives encompassing 9,500 square miles were studied. Given the enormity of the study area and the complex and varying aspects of the study itself, the utilization of GIS in conjunction with COGO technology appeared to be a time-saving and cost-effective approach. This paper will discuss the applications of the software and the results in terms of quality of data generated and overall effectiveness of the programs in satisfying project needs. An overview of the functional design process, the coordination efforts required to utilize both COGO and GIS, and the advantages and disadvantages of data transfer between the two systems will be addressed. Additionally, this paper will provide suggestions for the future application of COGO/GIS on projects similar in nature and scope.
