if the residuals are small, indicating that the correction is qualified, click on "Application" and
select "Yes" in the pop-up prompt.
Note: (1) Known points are best distributed at the edges of the entire job area, for example,
if point correction is done with four points, the measuring job area is best inside the quads
connected to the four points.
(2) Be sure to avoid the linear distribution of elevation control points, for example, if you use
three elevation points for point correction, the triangle composed of these three points should be
as close as possible to the positive triangle, if it is four points, as close as possible to the square,
we must avoid all known points of distribution close to a straight line, which will seriously affect
the accuracy of the measurement.
Once the point correction is complete, you can start measuring/lofting and so on. Only the
first job in the same project requires point correction, and subsequent jobs require only a single
control point base station translation.
