Backsight
The backsight wizard helps you specify a reference direction of a Total Station survey.
- In the Occupation Point group you can:
- Enter the name of the Point, where the total station is located. You can set the occupation point in one of the following ways:
- Type in the height of the instrument (HI).
Click
to select the way to specify the scale factor for the given occupation point. You can set either Scale factor is equal one, or type in custom value to the User Scale or set scale for the current Grid projection (if a project is selected). The asterisk (*) will be added to the scale value, if you have updated the initial value of the Scale field.
- In the Backsight Point group you can:
- Select between Point / Azimuth to enter either the name of the backsight location or the direction to it. You can set the backsight direction in one of the following ways:
- Enter the height of the reflector. Type the value manually or click the button with current reflector icon to select one of the previously used values from the context menu. If prism is used as a target you can also quickly review or change its configuration: select Edit from the context menu to open the Prisms dialog.
- Select Fixed Height if you want to fix the height of the backsight point for the whole set of measurements. This is useful when one target is mounted at the BS for the duration of an occupation and another is used for sideshots in mode Ang/Dist Sets-Dir/Rev
Note: If the occupation point has no elevation (i.e. is a 2D point), the backsight point measured using azimuth will have no elevation. As the result, all topo points measured with this setup will also have no elevation.
If you have entered a new backsight point, the software prompts you to enter the point coordinates in the Add Points dialog before starting of measurement.
- Select the Observation info check box to open the Observation info dialog, where you can enter meteo data during the session.
- Click the Next button to continue.

- Type in the name of the point.
Note: If you have entered a new point name, the software will prompt you to manually enter this point coordinates in the Add Points dialog.
- Choose the point from the map
. - Choose the point from the list
of the job points.
- Enter the height of the instrument (HI) in the current units.
- Click Next to select a known point. More...
The icon
brings up the pop-up menu of additional options. More...
Reference Direction Point
Select a start point for setting the reference direction:
-
Select a Point by typing its name, selecting it from the map
or from the list
.
Note: If you have entered a new point name, the software will prompt you to manually enter this point coordinates in the Add Points dialog.
Note: If the design point has no elevation (i.e., is a 2D point), the result point will have no elevation as well.
- The plot below will schematically show your selections.
- Click Next to take measurements. More...
Point Measurements
Setup a point on a reference line and sight to it:
- Enter the height of the reflector. Type the value manually or click the button with current reflector icon to select one of the previously used values from the context menu. If prism is used as a target you can also quickly review or change its configuration: select Edit from the context menu to open the Prisms dialog.
- Click

Reference Direction Azimuth
In this dialog you need:
- Type the name of a unknown Point on the reference line.
- Enter the azimuth value of the "Start Point - This Point" line in the Line Azimuth field.
- Click Next to take measurement. More...
Reference Direction Results
The dialog shows the setup information graphically. The instrument location is solved based on a reference line with known point and known azimuth and performed measurements. Click Accept to store the new instrument coordinates in the database.
Pop-up menu
Additional options which can be useful are as follows:
- Setup - click to expand the menu:
- PTL Mode - the coordinate of the measured points will be displayed from the specified reference line.
- Setup instrument for 3DMC. If this item was selected before performing Resection procedure, after clicking
in the Store Point dialog, the occupation point coordinates, horizontal circle value and instrument height will be sent to the total station automatically. The horizontal circle value is equal to the BS azimuth value. The instrument height value is used for calculating the elevation of the instrument center mark. The dialog of the instrument will show this elevation. The field HI of the dialog will show "zero".
- Edit: opens the Points list to edit points.
- Inverse: opens the Two-Point Inverse calculation dialog.
- Robotic: click to expand the menu:
