11.1.1 Resection
If the coordinates of an occupied point are unknown, a resection can be performed to
compute these coordinates. A resection involves the measurements from an occupied
point to several other points with known coordinates. It is possible to perform a
resection by measuring angles and distances or by measuring angles only. The type of
measurements influences the minimum number of observations needed to perform a
resection. In case of angle as well as distance measurements a minimum of 2
observations are required, by measuring angles only a minimum of 3 observations
should be performed.
