Fieldwork
51
Note: If the Backsight Circle displays a non-zero value, the angle
displayed is subtracted from all horizontal angles that are read
during data collection and the resulting points are adjusted
accordingly. This will happen after survey with true azimuths or
performing stakeout in a special mode. If you do not want this to
happen, you should change this value to zero from the Backsight
Circle dialog box by tapping the
%DFNVLJKW &LUFOH
button.
Most non-staking related data collection is performed from the
Traverse / Sideshot screen. When you take a shot using the
7UDYHUVH
button, the routine expects that you will eventually be occupying the
foresight that you are shooting and backsighting your current occupy
point. When you are ready to setup on the next point, the occupy,
foresight and backsight points will automatically be updated
accordingly.
After taking a shot using the
6LGH 6KRW button, the routine does not
expect the total station to be moved before the next shot and will
therefore only automatically advance the foresight point.
Data Collection Example
This section illustrates the necessary setup and usage of the Traverse
/ Side Shot screen, which is the primary screen used during data
collection. We will create a new job and manually add another point
to the job to use as a backsight. We will run in manual mode so the
shot data must be entered manually. This example, and the following
stakeout example are the only examples that are designed where the
user should follow along and enter the values in their data collector
as they are provided in the example.
