Domain Group editor

Add item

Add groups to this group domain.

With a group domain, you can permanently slice or classify a value map with the Slicing operation or by using the CLFY function in MapCalc.

This dialog box appears when in the Domain Group editor:

Dialog box options:

Upper bound:

Type a value for the upper boundary of a new group.

To create for instance a group between 50 and 100, type 100.
You can use boundary value 50 as the upper boundary value for another group, e.g. for values between 0 and 50.

Name:

Type a name for this group, e.g. medium. Group names can be as long as you like.

Note: Group names may contain any characters, except the % character.

In the sliced/classified map, you will see the group names when pressing the left mouse button (Info) in a map window; you will see the group names as record names when creating an attribute table for this domain (or for a map using this domain); and when enclosed in double quotes, you can use the group names in calculations. You can also show group names in the legend of the sliced/classified map.

Code:

Optionally, type a short code for the group name.

Note: In codes, colons : and percentages % may not be used.

When displaying the sliced/classified map in a map window and pressing the left mouse button (Info), and in Pixel Info, you will see the code and the group name as code: group name. When enclosed in double quotes, you can use codes in calculations. You can optionally show codes in the legend of a sliced/classified map.

Description:

Optionally, type a longer description for this group.

You can use descriptions for example in the legend of a sliced/classified map.
