Two-dimensional tables   

A two-dimensional table is used to combine or reclassify two raster maps with a class or ID domain. It defines a value for each possible combination of input classes or IDs.

A two-dimensional table view consists of rows which represent one domain and of columns which represent another domain. In the two-dimensional table, you have to assign a value, class name or ID to the fields which represent the combination of these domains.

When you apply the two-dimensional table on the command line of the Main window, you need two input raster maps which have the domains as used by the two-dimensional table, the output raster map then contains the values, classes or IDs that you entered in the fields of the two-dimensional table.
