Title: Comparison of methods for mapping forested trails using remote sensing at Umstead State Park

Abstract: Hill, Steven. Master of Natural Resources - GIS Technical Option. Title: Comparison of Methods for Mapping Forested Trails Using Remote Sensing at Umstead State Park. In this project I demonstrate the usefulness of high resolution LiDAR surveys in mapping forested hiking trails. The study builds off previous studies in which the “break in slope” profile of roads is used to delineate road features in rough, forested terrain. Formal hiking trails in certain topographies also exhibit this same profile. The study site for this report is Umstead State Park, in Wake County, North Carolina. A comparison of LiDAR’s increased capabilities to delineate features is also conducted with high resolution orthophotography. Using this approach, the two selected trails were mapped with completeness of 68.9% and 80.8% of their predetermined lengths. Field verification of features revealed a 93.3% producer’s accuracy for both trails.
