Geographical patterns of Corine land cover diversity across Europe : The effect of grain size and thematic resolution

Auteur(s) et Affiliation(s)



Description :
The AA. examine Corine land cover diversity patterns across Europe, and test (1) if geographical (longitudinal, latitudinal) gradients exist, (2) if the scale of analysis (and specifically the grain of analysis) influences the patterns, and (3) if the thematic resolution affects the results. To account for spatial autocorrelation, they used Clifford’s test. Latitude was significantly correlated with land cover diversity only at large grain sizes. Longitude, with a few exceptions at fine grain, was not correlated to land cover diversity. Fine grain analysis displayed autocorrelation, but over short distances, while large grain analysis displayed autocorrelation over longer distances. Increasing the detail of the thematic resolution seems to have effects similar to increasing the grain size. The thematic resolution in certain cases influenced the results qualitatively and thus inference from low-resolution landscape analysis should be done with caution.
