Results

In the Results tab, observe the calculation outputs and click the Tab to save the data to a txt file if required:

  • The calculated Area in (JobUnits)^2, acres and hectares.
  • Perimeter of the polygon.
  • The tolerance interval calculated as Area (in meters) minus/plus Perimeter multiplied by 1.25
  • The list of points constituting the polygon vertices in the correct order.
  • The Map tab shows the illustration for the results.
