Line and offset
To calculate coordinates using Line and Offset:
1. From the
Cogo
menu, press
[4]
(or press
[v]
and
[REC/ENT]
)
to select
LineOff
.
The
Input P1
screen appears.
2. Enter the base point (P1).
For the input method, see Step 2 of the Inverse PT-PT
method on page 104.
3. Enter the AZ angle. A value can be entered in either the
AZ or P2 field to specify the azimuth P1-P2.
4. Enter the horizontal distance along the baseline (STA).
5. Enter the horizontal distance perpendicular to the line
(O/S).
Note –
A negative value in the STA field means the opposite
direction along the defined azimuth line. A negative value in
the O/S field is for the left side of the azimuth line.
6. Enter the vertical distance (dVD).
7. To calculate the coordinates of the point, press
[REC/ENT]
in the dVD field. The Z coordinate can be
changed here.
8. To record the point, press
[REC/ENT]
in the CD field.
The coordinates are stored as a CC (calculated coordinates) record. Line definition information
and STA, O/S, and dVD values are stored in comment (CO) records.
