Pane of list of points

Contains serial numbers of entered control points of calibration and coordinates of X and Y of these points in map coordinate system.

Inaccuracy

Displays the number from 0 to 100% characterizing non-linear inaccuracy of performing calibration.

If less than three control points are specified, inaccuracy value is not displayed (there is not enough data for building affine transformation).

If exactly three control points are specified, displayed value of inaccuracy is equal to 0 (built affine transformation transforms coordinates of all control points precisely).

If not less than four control points are specified, inaccuracy value reflects the quality of performing calibration.

Add

Serves for adding a new control point. A dialog box “Coordinates of control point” is opened.

Change

Serves for changing the control point selected in the list. A dialog box “Coordinates of control point” is opened.

Remove

Removes the control point selected in the list.

OK

Completes the calibration procedure and closes the dialog box.

Cancel

Cancels all performed actions and closes the dialog box.
