16 Resection
Resection is used for station setup on an unknown point. The
station coordinates and the Hz-circle orientation at the station are
calculated from measurements to two known points.
In building and construction sites, resection can be used where the
establishment of a permanent station is not practical, or where a
marker is likely to be destroyed.
For Stake out, data collection or cadastral survey, resection allows
you to choose the instrument location with the best view of the
working area.
