Title: Topographic Position Index-Based Landform Classification
Version: 0.3.0
Authors@R: person("Gianmarco", "Alberti", email = "gianmarcoalberti@gmail.com", role = c("aut", "cre"))
Description: Classifies a landscape into slope-position and landform classes on the
    basis of the Topographic Position Index (TPI) and slope, following
    Weiss (2001) and Jenness (2006). Two classifications are offered: a
    six-class Slope Position Classification, based on one TPI scale, and a
    ten-class Landform Classification, based on a small and a large TPI
    scale. The TPI can be computed over square, circular or annular
    neighbourhoods, sized in cells or in map units, and standardised
    either over the whole grid (as in the original method) or locally.
    Results are returned as an object holding the classified raster, the
    TPI and slope surfaces, and per-class descriptive statistics, with
    methods for printing, summarising and plotting.
