6.2. Stake Out
This application calculates the required parameters to position the required stakeout point. The stakeout point data
can be read from the instrument memory or set by manual input. The program guides the user step by step from
the current point to the correct point by continuously displaying the relative position relationship between the
current prism point and the point to be stake out.
There are two methods for the process of stake out: the cartesian method and the polar method.
Cartesian Stake Out:
Stake out method which is based on a cartesian coordinate system. The calculated offset is divided into three
orthogonal distance elements.

Polar Stake Out:
Stake out method which is based on a polar coordinate system. The calculated offset is divided into one angle
and two distance elements.
