Reference Line
Measuring and staking out of points is possible for <R-Time Mode: Rover> and <R-Time
Mode: None>.
Reference lines/arcs can be created from points stored as:
•
WGS 1984 geodetic
•
Local grid
Heights and positions are always taken into account. Points must have full coordinate
triplets.
The properties stored with staked points are:
•
Class: Either MEAS or NAV depending on the position status when the staked point was
occupied.
•
Sub class: GPS Fixed, GPS Code Only, GNSS Fixed or GNSS Code Only
•
Source: RefLine (Grid), RefLine (Meas), RefLine (Stake) or RefLine (Poly)
•
Instrument source: GPS
A point that is used to define a reference line/arc can be deleted. A reference line/arc can still
be used if one or more points defining the reference line/arc have been deleted. Within
REFLINE Edit Reference Line and REFLINE Edit Reference Arc the deleted point field is
shown in grey. Within MapView the reference line is still displayed but the deleted point or
points is/are not.
Reference point:
The term reference point is used in this chapter to refer to the point
from which the perpendicular offset from the reference line/arc, to the
target point, is measured. Refer to paragraph "Defining a reference
line/arc" and the diagrams for further explanation.
