Topographic\ndistances can be calculated along shortest topographic paths\n(Wang (2009) ), weighted\ntopographic paths (Zhan et al. (1993)\n), and topographic least cost\npaths (Wang and Summers (2010)\n). Functions can map\ntopographic paths on colored or hill shade maps and plot\ntopographic cross sections (elevation profiles) for the paths.", "License": "GPL-3", "Encoding": "UTF-8", "LazyData":
