Comparing Qualitative Raster Maps

Abstract. Spatial diversity of the natural environment can be presented using raster qualitative data. They can be the result of collecting field data or be the result of stochastic modelling of a certain complexity of the environment. One example of such modelling is the determination of similar elements of relief forms on the basis of morphometric variables. The use of unsupervised methods for clustering raster data in modelling can produce different maps. It is necessary to assess the compatibility of the obtained maps in order to assess how significant the differences between them are. The article presents selected stochastic and deterministic methods for assessing the spatial distribution of data. Exemplary methods of measuring variability at the global and local level were discussed.
