4.4 RESECTION
The “Resection” is used for determine the
instrument position from measurements to a
minimum of two known points.
Note: a) If the angle between the first
measurement point and the second one is too
small or too large, it will influent the geometrical
accuracy of calculation result. So selecting a
geometrical graphic with good structure is
important.
b) The calculation requires at least three angle
data or two distance data.
c) Basically, the station height is calculated by
the distance data. If the distance data was not
carried out, the height will be determined by
the angle of known point.
The standard deviations and residuals for
accuracy assessments are provided.
