geographic positions that form the line or area.

symbol you want to create.

click in the area of the circle where you
want the first point of the line or area
positioned. The first point is created as a
small red circle and its LAT/LON position
is shown, you can edit the position by
changing the LAT/LON values.

The points previously
created appear as white
circles and the last created

points to be correctly specified.
