On the Trail of the Appalachian Scenic Corridor: Using GIS To Find an East-West Route Across North Georgia
Michael GilbrookHDR Engineering used a combination of GIS tools to locate a feasible road corridor through the southern Appalachian Mountains of north Georgia for the Georgia Department of Transportation. An ArcInfo least-cost path model employing twenty-eight ARC GRID layers identified potential routes in Phase I. Throughout all three Phases, ArcInfo quantified potential environmental impacts and engineering considerations for potential corridors such as historic sites, wetlands, stream crossings, historical accident data, and vertical profiles. We employed ArcView GIS to explain the study's findings to residents at public meetings using the same GIS coverages that drove the analysis.
