Calculating Topographic Paths and Distances

A toolkit for calculating topographic distances and identifying and plotting topographic paths. Topographic distances can be calculated along shortest topographic paths (Wang (2009) ), weighted topographic paths (Zhan et al. (1993) ), and topographic least cost paths (Wang and Summers (2010) ). Functions can map topographic paths on colored or hill shade maps and plot topographic cross sections (elevation profiles) for the paths.
