Figure 19-10 Transformation parameter of points
(1) Input known point coordinates
Input the known-point plane coordinates of current measurement points.
(2) Smooth conditions setting
Times: Select smooth times, including "10 times", "50 times", "100 times"
and "manual shutting down".
Solution types: Select GPS data conditions, including "single point
positioning", "finite difference solution" and "fixed solution". For example, if
"finite difference solution" is selected, smoothing computation can only be
performed only when the GPS calculation accuracy reaching to finite
difference solution or above.
(3) Transformation parameters of calculation points
Click [Smooth] to collect GPS measuring coordinates. Perform smoothing
computation. Click [Stop] to terminate smoothing acquisition. Click [Apply].
Apply the current calculation results on point transformation parameter.
