Measuring Traverse

From the Traverse - Select screen select one of the following:
• F1 ...w/o known Backsight: Starts the traverse without a known backsight. The
measurements begin to a foresight point.
• F2 ...with known Backsight: Starts the traverse with a known backsight.
• F3 ...with known Azimuth: Starts the traverse with a user-defined azimuth.
Start a traverse without a known backsight
• Start on a known point without an initial measurement to a known backsight.
• Stop on a known point, or make a final foresight measurement to a known
closing point.
If the coordinates of the start station are unknown, the Station Setup program can be
run before the traverse. A Helmert transformation will be performed at the end of the
traverse.
If the traverse is left open, then the calculations are based on the system azimuth.

TSOX_059
Start a traverse with a known azimuth
• Start on a known point, aim to any direction (e.g. a tower) and define this direc-
tion as the reference. This method is often used to define a 0-direction.
• Stop/end the traverse either on a known point or a traverse point and then
measure to a known closing point, or leave the traverse open. Refer to "7.14.5
Closing a Traverse".
If using the current system azimuth, for example from the Stn.Setup program, then
simply confirm the suggested Hz-value in the Set Horizontal Angle screen.
