| - | <note tip> **TIP**: the region approach is a helpful way to break the map into several subsets either to customize a submodel, for example to run with different parameters per country, state or county, or to optimize the memory usage as the model does not need to handle all the map cells for a specific calculation or processing, but only the cells selected from a region per time</note>\\ | + | |
