-In this step, you will identify the suitable areas equal to or greater than 1000 hectares. First, delete //[[:Save Map]]// ''​five_criteria_combined.tif''​. Remember that the less the software accesses the disk, the faster the model runs. Now, drag from Map Algebra tab the functor [[:Calc Patch Label Map]]. This functor labels patches of cells using sequential numbers. A patch consists of a continuous group of neighboring cells of the same category ​(see also [[landscape_metrics_in_dinamica_ego|Landscape metrics in Dinamica EGO]]). You need this in order to solve the area criterion. Connect the output from "​Combine Five Criteria"​ to it. Some of its parameters are:+In this step, you will identify the suitable areas equal to or greater than 1000 hectares. First, delete //[[:Save Map]]// ''​five_criteria_combined.tif''​.
