Description
Point to
current
position
The direction, distance and coordinate differences between
the current rover position and a known point can be calcula-
ted depending on the data available. Points with full coordi-
nate triplets, position only points and height only points can
be used.
Elements that must be known are
•
coordinates of one point.
The coordinates of the known point
•
can be taken from the job.
•
can be manually measured during the COGO calculation.
•
can be entered.
Current
position to
line
The direction, distance and coordinate differences between
the current position and a given line can be calculated
depending on the data available. Points with full coordinate
triplets, position only points and height only points can be
used.
Sufficient information must be known to define a line.
The coordinates of the known points
•
can be taken from the job.
•
can be measured during the COGO calculation.
•
can be entered.
Point to line
The direction, distance and coordinate differences between a
known point and a given line can be calculated depending on
the data available. Points with full coordinate triplets, posi-
tion only points and height only points can be used.
Sufficient information to define a line and the coordinates of
one point must be known.
The coordinates of the known points
•
can be taken from the job.
•
can be measured during the COGO calculation.
•
can be entered.
Point to arc
The direction, distance and coordinate differences between
the current position and a given arc can be calculated
depending on the data available. Points with full coordinate
triplets, position only points and height only points can be
used.
Sufficient information to define an arc and the coordinates
of one point must be known.
The coordinates of the known points
•
can be taken from the job.
•
can be measured during the COGO calculation.
•
can be entered.
