18.POINT PROJECTION

Point projection is used for projecting a point onto the baseline. The point to project can be either measured or
input. Displays the distances from the first point and point to project to the position at which a line extending
from point to project intersects the baseline at right angles.

18.1 Defining Baseline

• Defined baseline can be used in both setting-out line measurement and point projection.
PROCEDURE
1. In the second page of OBS mode screen, press [MENU],
then select "P-Project".
2. Enter the instrument station data then define the baseline.
