Point Average
is a processing command useful in obtaining both the average value of a set of readings as well as
estimates of the variation of the data. If 100 points are measured from 301 to 400, the calculation of the average is
shown below:
Individual points can be turned on and off for purposes of the calculation. The standard deviation is presented. The
range of points is entered using the standard FAST Survey convention of dash and comma separators. For example to
average points 401 to 410 as well as 415 and 420 to 425, the entry format would be 401-410,415,420-425. Additional
points can be added using the "From List" and "From Map" icons. When new points are added or points are turned on
or off, clicking Average initiates a fresh calculation. To store the averaged coordinate values as a point ID, click the
"Store to Disk" icon at the top of the screen. Click the back arrow to return to the main COGO menu screen.
