Area determination

If you don't need the points' precise coordinates, but areas are enough, you can use the shortened calibration of the digitizer without identical points using only known distances. In such case, follow the steps below :

  1. In the digitization window, check the option Direct reading.

  2. Press the button (Calibration).

  3. Enter the real distance between two points in the displayed dialog window, in the horizontal and vertical directions.

  4. Press the button (Show the length) and display both end points of the distances on the digitizing device. The measured distances will display in the dialog (in the graphic coordinates of the template).

  5. Press the button (OK). This terminates the shortened calibration.

Now, the digitizer will provide the coordinates in the local system, in the correct scale, so it can be used, for example, for area determinations.
