Resection Measurement - Sokkia SRX1 Operator's Manual

16.RESECTION MEASUREMENT

Resection is used to determine the coordinates of an instrument station by performing multiple
measurements of points whose coordinate values are known. Registered coordinate data can be
recalled and set as known point data. Residual of each point can be checked, if necessary

• Between 2 and 10 known points can be measured by distance measurement, and between 3 and
10 known points by angle measurement.
• The more known points there are and the more points there are whose distance can be measured,
the higher the precision of the coordinate value calculation.
• It is possible to allocate softkeys in the Coord. measurement menu to suit various applications and
the ways that different operators handle the instrument.
