Cartographic Scale and Minimum Mapping Unit Influence on LULC Modelling

摘要

Two models at two different scales (1:25.000 and 1.100.000) were calibrated using two different Land Use and Land Cover maps at such cartographic scales (SIOSE and CORINE) and with a different Minimum Mapping Unit (0.2-0.5ha and 25ha). Differences between models were assessed through cross-tabulation analysis (quantity and allocation disagreement) and spatial metrics (pattern disagreement). The models results have been very different depending on the scale considered, although most of the disagreement comes from the contrasting input maps. In any case, the scale at which the models were calibrated have proved to influence the pattern modelled and the quantity and allocation of changes.
