topoDistance

A toolkit for calculating topographic distances and identifying and plotting topographic paths. Topographic distances can be calculated along shortest topographic paths (Wang (2009) doi:10.1111/j.1365-294X.2009.04338.x), weighted topographic paths (Zhan et al. (1993) doi:10.1007/3-540-57207-4_29), and topographic least cost paths (Wang and Summers (2010) doi:10.1111/j.1365-294X.2009.04465.x). Functions can map topographic paths on colored or hill shade maps and plot topographic cross sections (elevation profiles) for the paths.
