- | These two set of metrics are input for more complex metrics, such as fractal dimension and largest patch index. For example, fractal dimension for a landscape class can be estimated using the perimeter-area relationship, if sufficient data are available, the slope of the line obtained by regressing log(P), patch edge lengths, on log(A), patch areas, is equal to 2/D (Burrough, 1986). Check other landscape metrics models, such as mean patch distance, largest patch index, in ''examples\landscape_metrics''. | + | These two set of metrics are input for more complex metrics, such as fractal dimension and largest patch index.
