8.3.2 Resection Method
Set up the instrument at a new point, and calculate the coordinate of the new point using the coordinate
data of maximum seven known points and the measurements made to these points.
By following observation, resection is possible.
•Resection by distance measurement: 2 or more points must be measured
•Resection by angle measurement only: 3 or more points must be measured
An occupied point coordinate value will be calculated by the method of least squares.
(In case that 3 known points are measured by angle measurement only, the value would not be
calculated by the method of least squares. )
