D.4.1 Automatic Grid Setup (Line-to-Line Navigation)
With the A-automatic-grid-setup option, you can generate a rectangular grid with parallel lines
separated by a specified increment
(for example, 100m). You must define the START and END
points (in UTM only) for the first line and the line increment.
If you enter a positive value for the increment, the lines are added in a counter-clockwise direction.
In the diagram that follows, a negative value has been used to increment lines below the initial line.
The system generates a grid with 500 lines (i.e. 1000 waypoints).
With waypoints, you can:
a)
use as many of the waypoints as required
b)
skip waypoints, for example, where obstacles are in the way
c)
stop the survey and re-start at another waypoint.
