Field Description Application
Perpendicular offset: Positive if stakeout point is to
the right of the reference line.
Reference Line
DTrav. Perpendicular offset:
Positive if stakeout point is to the left of the meas-
ured point. (←)
Negative if stakeout point is to the right of the
measured point. (←)
Stakeout
Calculated distance perpendicular from the refer-
ence line.
Reference Line
VA Vertical angle to the point. Commonly used
VD Height to the point. Commonly used
DY/E Easting offset:
Positive if stakeout point is to the right of the
measured point.
Negative if stakeout point is to the left of the
measured point.
Stakeout
DY/N Northing offset:
Positive if stakeout point is further away from the
station than the measured point.
Negative if stakeout point is closer to the station
than the measured point.
Stakeout
DZ/H Height offset:
Positive if stakeout point is lower than the meas-
ured point. (↓)
Negative if stakeout point is higher than the
measured point. (↑)
Stakeout
Z Height coordinate of the point. Commonly used
Height offset: Positive if stakeout point is higher
than the reference line.
