Corner & Plane
[Survey] [Corner & Plane]
The Corner and Plane screen is used to store a point using a reflectorless total station for a point that cannot be shot,
but three points on the same plane can be shot.
Foresight: The name of the point that will be stored.
Description: The description for the point that will be stored.
HR: 0.000: Shows that no rod height will be used with this routine since all shots are direct reflectorless.
[Shoot Plane]: Prompts you to take three shots on the same flat surface that the new point is located.
Note: Each shot can be in any location on the same plane, but they must not form a straight line and they should not
be grouped close together.
[Aim at Corner]: Prompts you to aim at the corner (the point that you want to store). Although no shot is taken, the
angles to the point will be used to compute its location.
Note: After all shots are done, the computed elevation is displayed for the new point. You can either enter a different
elevation or tap
to accept the computed elevation.
[Backsight]: Opens the
screen you can set and check your station occupy point and backsight.
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: The name given to the next stored point.
Description: The description given to the next stored point.
HR: The length of the rod.
: Opens the
Number of Sets: The desired number of sets required when shooting each foresight. You must select at least one set.
[Traverse]: Prompts 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
dialog box will open and inform you of the updated points.
