Change domain of table

Dialog box

The Change domain of table operation copies the contents of an input table to a new table; the new table will have another domain than the input table.

For the domain of the output table, you can choose:

Dialog box options:

Input table:

Select an input table. Open the list box and select the desired input map, or drag a raster map directly from the Catalog into this box.

Change domain to:

Choose whether you want to change the domain of the table to a class or ID domain of a column in the table, or to an existing class or ID domain on disk.

Column:

Select a class or ID column from the table; the domain of this column will be the domain of the output table.

Domain:

Select an existing class or ID domain from disk.

Aggregate:

Select this check box when you selected a class or ID column from the table and when the class names or IDs in that column occur more than once, i.e. are not unique. Subsequently, select an aggregation function: average, minimum, maximum, sum, last. The values of value columns in the input table will appear aggregated in the output table according to the selected aggregation function.

Clear this check box when the classes or IDs in the selected column are unique.

Output table:

Type a name for the output table.

Description:

Optionally, type a description for the output table. The description will appear in the status bar of the Main window when moving the mouse pointer over the table in a Catalog, and in the title bar of a table window when the output table is displayed. If no description is supplied, the output table will use its own definition as description.

When you click the Show button, the dependent output table will be defined, calculated and shown. When you click the Define button, the dependent table will only be defined; if necessary the table will be calculated later, for instance when the table is opened to be displayed.
