 Now you need to sum all cells that represent forest. Note that the output is a binary map with only ones and nulls, the latter is represented by zero. Next, use //[[:Extract Map Attributes]]// (Map Algebra tab) to extract the sum of non-null cells.  This functor produces as output a table with   [[:extract_map_attributes#Notes|these map attributes]].{{ :tutorial:inc._it._model_6.jpg |}}
-The area extent is the sum of non-null cells (field 9) multiplied by the cell area in hectares (field 7). You need to add one //[[:Calculate Value]]//, located in the Table tab, to perform this calculation. Also, drag one //[[:Number Table]]// into it (from Map Algebra Supplementary tab), which will receive the attribute table output from //[[:Extract Map Attributes]]//. You need to enter "1" to assign an identifier for this table. Finally, write:\\ **t1[7]*t1[9]**\\ (cell area (in hectares) * sum of the values (excluding null cells))

 Now you need to fill in a table in order to store the area calculated for each state. The functor [[:set_lookup_table_value|Set Lookup Table Value]] updates a lookup table placing a value to a position defined by a key. To fill in the entire lookup table, you need to develop a loop that enables this functor to browse through the lookup table. To close this loop, you will need a functor that is key to the development of dynamic models. Here we introduce the concept of Mux functor.
-A //Mux// functor can be a map, a categorical map, a lookup table, a table or a value. Look at the Control tab to find //[[:Mux Lookup Table]]// and drag it into //[[:Repeat]]//. Also drag //[[:Set Lookup Table Value]]// from the Table tab.
