Mask segments

Dialog box

The Mask Segments operation allows you to selectively copy segments of a segment map into a new segment map. The user has to specify a mask to select and retrieve the class names, identifiers or values of the segments that are to be copied. For more information, see Mask Segments : functionality and How to use masks.

Dialog box options:

Input segment map:

Select an input segment map. Open the list box and select the desired input map, or drag a segment map directly from the Catalog into this box. No special input map requirements.

Mask:

Type (multiple) search strings to find the segments that you want to copy. For more information, see Mask Segments : functionality and How to use masks.

Output segment map:

Type a name for the output segment map that will contain the copied segments.

Description:

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

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