In other words, a set of characteristics is being used to split into two classes something that could be defined as one thing. Nonetheless, their distinction is important for communicating key characteristics, geomorphic setting, and inferred processes.

  • Digital classification of hillslope position

    Classification of elevation rasters with this digital model of hillslope position represent base maps that can be used to (1) improve research on toposequences by providing explicit definitions of each hillslope element’s location, (2) facilitate the disaggregation of soil map unit complexes, and (3) identify map unit inclusions that occur due to subtle topographic variation.
