The second screen is used to perform the actual point slope staking shots.
Rod Elev: is the current elevation at the rod location.
Des. Slope: is the design cut or fill slope.
Obs. Slope: is the computed (observed) cut or fill slope based on the last shot and the corresponding hinge point.
HD to HP: is the horizontal distance from the rod to the hinge point.
Cut to HP / Fill to HP: is the cut or fill required to bring the current rod location level with the hinge point.
To Slope Offset: is the perpendicular offset between the rod location and the horizontal line from the hinge point to
the catch point.
Direction (CW or CCW): is the horizontal angle (clockwise or counterclockwise, respectively) that the rod must turn
around the hinge point for it to be over the line from the hinge point to the catch point.
Below DS / Above DS: is the vertical distance that the rod is located below or above the design slope. If the
[Automatic Slope] option is selected, this will be the distance to the nearest slope, otherwise it will be the distance to
the selected (cut or fill) slope.
Toward HP / Away HP: is the estimated horizontal distance the rod must move toward or away from the hinge point
before it is over the catch point.
Note: The computed horizontal distance is based on the observed terrain computed from the last two shots. If only one
shot has been taken, this value will be blank.
EDM: This button can be toggled to shoot in various EDM modes. The options available depend on the total station
being used. Consult the total station’s documentation for more information on the EDM modes that it supports.
[Results]: This will open the Slope Staking Results screen, listing detailed information for the current setup and last
shot.
Note: The [Results] button is only available from the Store Catch Point screen when using GPS or Remote mode,
which is accessed after tapping [Store >].
The button described below selects which information is displayed in the screen from the following options:
[Vertical Map]: displays a cross-sectional view at the current station.
Note: When you tap a map view, an expanded view of the same map will fill the screen.
Note: The Vertical Map will show an X at the location of each previous shot. This can be useful in determining if the
current terrain will never intersect the slope (no catch point).
[Horizontal Map]: displays an overhead view of the job.
[Shot Data]: displays the shot data for the last shot.
The button described below selects the type of slope that will be used from hinge point to the catch point from the
