Shoot From Two Ends
Survey Shoot From 2 Ends .
The Shoot From 2 Ends screen is used to provide more accurate
vertical closure to a traverse. The routine requires that a foresight
point is shot, but it is not stored until after it is occupied and another
shot is taken to the previous occupy point. The coordinates for the
foresight point are computed from an average of data gathered at
each occupy point.
Foresight: is the name given to the next stored point.
Description: is the description given to the next stored
point.
Number of Sets: is the desired number of sets required
when shooting each foresight. You must select at least
one set.
HR: is the length of the rod.
: opens the Smart Target options (Page R-444).
Backsight… : accesses the Backsight Setup screen (Page
R-114) where the current backsight can be modified.
Traverse : will prompt you to shoot the Foresight point.
After each set is performed, the Move To Other End
dialog box will open and prompt you to set up on the new
point and enter a new instrument and rod height. The New Occupy
Point dialog box (Page R-122) will open and inform you of the updated
points.
: is a shortcut to the Surveying and Repetition Settings screens
(Page R-44 and R-51 respectively).
