The landform map (geomorphons) was created using the Geographic Resources Analysis Support System (GRASS) software (GRASS Development Team 2013) through the geomorphons algorithm (Jasiewicz and Stepinski 2013; the code can be downloaded from http://sil.uc.edu/geom/app, accessed 16 April 2014).

Classified terrain units were verified through a field based landform map resulting in an accuracy of 70%.
They compared the results from both techniques with a landform map created by manual airphoto delineations.
The interpretation of Radcliffe (1979) and the landform maps produced by Tonkin (1984), however, infer that spur strata are defined as hillslope areas between convergent hollows.
