- | This subset of functors permits division of a map into several regional maps, which can be input for separate models or submodels, whose parameters are customized for each map’s region. Let’s adapt the model ''Calc_forest_remaining_per_state'' (LINK) to use the concept of regions. First open the Region Tab in the library window.\\ | + | This subset of functors permits division of a map into several regional maps, which can be input for separate models or submodels, whose parameters are customized for each map’s region.
