It covers the number of different land cover types (m) observed along the straight line and their relative abundances (P i ). It is calculated by dividing the Shannon diversity index by its maximum (h (m)). Therefore it varies between 0 and 1 ...

Webrichness, for q = 15) it is Shannon diversity, i.e. effective number of species derived from Shannon entropy, and for q = 2 it is Simpson diversity, i.e. ENS for Simpson concentration index. For q > 0, indices discount rare species, while for q < 0 the indices discount common species and focus on number of rare species (usually not meaningful).
