Now place //[[:Calculate Map]]// and //[[:Number Map]]// within it. Enter "1" in **Map Number** in //[[:Number Map]]//. Now place //[[:Save Map]]// and enter ''unconstrained_areas.tif'', make sure you have changed the folder to lesson5.

| <note tip>**TIP**: you can increase model performance by avoiding saving intermediate map files. In this step, you will save the map just to check the result from this operation. Do not forget to connect all functors.</note> | <note tip>**TIP**: you can increase model performance by avoiding saving intermediate map files.

| - | 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''.
