Fig. 4. Effect of increasing grid cell size used in prior-classification interpolation (PCI, left) or window size used in postclassification filtering (PCF, right) on selected landscape pattern metrics describing the categorical maps of yield classes at Sites A and B. Landscape metrics shown are patch density (PD), the total core area per field (TCA), the mean core area per patch (MCA), the contagion index (CONTAG), and the splitting index (SPLIT). All values refer to hierarchical cluster analysis using the Ward method.
