Field Option Description
The first position (b) the instrument points
to is defined by the 2D coordinates (a) of
the point to stake out ( = horizontal direc-
tion) and the current vertical angle. There-
fore, aim the instrument at the approximate
position of the point to stake out.The meas-
ured 2D position is compared with the stake-
out position to determine a new position (c)
to aim at. As no information about the natu-
ral surface is available, a point at the same
height as the measured position is calcula-
ted. The new position (d) is measured and
compared again with the point to stake out
(a).This iteration process runs until the toler-
ances defined for the stakeout are reached.
