The same dialog box can be reached via Change…, the title then is Change hard ground region instead of New hard ground region, the functionality is otherwise alike.

Find it here:

NCO: Select a hard ground region

In this dialog box, you define/change a hard ground region. A hard ground region must be limited by a polygon.

• Identity - Identity may consist of a random selection of letters and other characters.

• Select polygon < - All dialog boxes are closed, and we get the opportunity to click a polygon in the drawing. As we click the polygon, we get back to the dialog box.

• Draw polygon < - All dialog boxes are closed, and we get the opportunity to draw a polygon. By pressing <Enter> we get back to the dialog box.

• OK - The dialog box is closed and the region is registered/changed.

• Cancel - The dialog box is closed without the region being registered/changed.
