Exercise 3973. Points 4, theme: Correspondence of Categorical Surfaces
Cross tabulate base map areal categories and soil types in map sheet 54443, relative overlay of which combination is statistically significant at p <= 0.05. Binary raster files muld54443.rst and PK54443.rst are in the attached archive, codes are in the rdc files.
Which five combinations have the highest co-occurrence relative to random placement?
Which soils are significantly (p < 0.01) avoided by private yards (code 66)?
Which land cover category is most probably overlied with eroded soils (code 4)?
