This is the number of the line to be smoothed.
Turns the smoothing on or off for any given line.
This controls the degree of smoothing applied to the selected line. The higher the value, the
greater the degree of smoothing.
This allows the User to select whether you would like to despike before smoothing.
This controls the distance that is considered a spike. The smoothing algorithm will calculate a
smoothing curve. It will then calculate the distance between the smoothed points and your original points.
If any of these distances are greater than the distance specified in jump, the point will be replaced by a
point on the smoothed curve. All points falling within the jump distance of the smoothed curve will be
smoothed. All points falling outside the jump distance of the smoothed curve will be left untouched.
It is recommended that the User perform a second smoothing after using the jump function to
despike the curve since the curve is not actually smoothed. The first smoothing spline is used only for
calculating if a given point is a spike. If smoothing is performed a second time, the program will smooth
the despiked data.
This enables the User to turn on a higher degree of smoothing. This will be performed
after the first despiking and smoothing have been performed.
This controls the degree of smoothing for the second pass smoothing; the higher the value,
the greater the degree of smoothing.
The User can also change the parameters for an individual line by selecting the line number and then
selecting Change Line Parameters. This is illustrated in Figure 133 for Line # 0.
In this example, we have changed the first smoothing parameter from four (the default value) to six for a
higher degree of smoothing. We have also increased the second smoothing parameter to four (default
value of two). We have also included a position despike with a jump of one meter. After selecting OK
these changes are reflected in the Line smoothing parameters setup dialog box.
To perform the smoothing, select Smooth. If all lines were selected for smoothing, a series of yellow lines
will be displayed that indicate what your smoothed data will look like after the changes are applied.
No changes are applied to the data until the User selects Close > Apply. If the results of the
smoothing operation are unacceptable, the User can exit the screen by selecting Close, or change the
smoothing parameters and select Smooth again.
