2: Multiple Resection
Setup station by angle/distance measurements to known PT
- Maximum 10 points can be used in Resection.
- Calculation starts automatically when enough measurements are taken.
- Deleting any poor observation data can be done.
- Selecting BS point is available.
Press the [2] key on the “Station Setup”
screen to display the screen for inputting
the number/name of known point 1.
When you input a known PT, it shows the
coordinate and proceeds to the target
height input.

If the angle between known point 1 and known point 2 (as measured
from the station point) is extremely acute or extremely oblique, the
resulting solution will be less geometrically reliable. It is best to select
known point locations (or station point locations) which will yield
strong geometry.
