Application Notes

This quality control tool enables the user to flag in green lines with points that exceed a set maximum data separation.

Since the ordnance are typically of a smaller scale, it’s important to have a good number of points in a short range to be certain to increase detection.

  • To properly display the sample separation on the map, hide the groups previously displayed in the area of interest of the Index map.
