%description
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.
