Aggregation based on attribute |
Select an integer zone attribute by which you want to aggregate the zones. |
|
Use attribute value as number of the aggregated zones |
Values smaller than 0 are invalid, for example. Since only active zones are aggregated, the numbers of passive zones are not available. If the attribute value cannot be used, the number is allocated automatically instead. This is indicated in the message window.
|
If the option has been selected, the value of the aggregated attribute will be allocated to the new zone as its number if this number is valid and still available. 
If the option has not been selected, the new zones are numbered automatically.6. Confirm with OK.
If an assignment result exists, a query opens.
7. Confirm with Yes.
8. Confirm another query with Yes or Yes for all.

Note: If you close the window with Cancel, your modifications will be discarded. |
The active zones are aggregated to a new zone.
