13.2 Point Projection
The baseline must be defined before performing point projection.
【Procedure of point projection】
1. Select “
3. Point projection” after finishing
defining baseline.
2. Input the point coordinate.
Press F2: [
MEAS] to measure the point to project.
When recording the data as a known point, press
key {
Func}, and press F2: [REC] on P2. Record
method, see Ҥ 23.1 Input Known Point Coordinate
by Keys”.
3. Press F4: [
OK] to calculate Length, Offset and dVD
will display.
Length: Distance along the baseline from 1
st
point
to 2
nd
point (X direction).
Offset: Distance from point to project to the
position at which a line extending from point of
project intersects the baseline at right angles (Y
direction)
dVD: Elevation between the baseline and the
projected point.
Press F1: [
NEZ] to display switching between coordinate and distance data.
Press F2: [
REC] to record the coordinate as a known data.
Press F4: [S-O] to switch to stake out measurement of the projected point. See “6 Stake
out measurement”.
Press key {
ESC} to continue point projection of a new point.
