Calc Combination Map

Description

Calculates a map combining two other maps. The calculation assigns an unique value for each possible combination of values from co-registered cells in the input maps. Each unique value used is stored in a dictionary of combinations. The combination dictionary is a table with format “Combination*#real, Initial#real and Final#real” where the key represents the combined value, and the data values represent the two original values from each one of the input maps.

Inputs

Name	Type	Description
Initial Map	Categorical Map Type	The initial map. This map corresponds to the “Initial” value column in the resulting dictionary table.
Final Map	Categorical Map Type	The final map. This map corresponds to the “Final” value column of in resulting dictionary table.

Output

Name	Type	Description
Combination Map	Categorical Map Type	Map depicting the combination of the two input maps.
Combination Map Dictionary	Table Type	Dictionary table used to translate the values assigned to each combination back into their corresponding initial and final value from the input maps. This table has format “Combination*#real, Initial#real and Final#real” where the key represents the combined value, and the data values represent the two original values from each one of the input maps.

Notes

The cell type of the output map is optimized to be the minimum cell type required to represent the combination of the two input maps.
