Here you can GPS calibrate your Yardage Book Image. GPS Calibration is necessary to map GPS Positions (e.g. Stroke Results) on the Yardage Book image. After calibration of the Yardage Book Image, you can visualize the Strokes as colored Lines painted over the Yardage Book image when generating a PDF File. To calibrate the Yardage Book Image you need to define at least 2 GPS Positions and manually map them to the Yardage Book image. The more positions you map manually, the better the Results will be.

In the List Box in the upper part you see all GPS Positions you already manually mapped.

Check Show quality of GPS Data to see the Quality of the GPS Positions. The Quality is determined by calculating the Position of each recorded Position on the Yardage Book Image using the other recorded Positions and comparing that to where the Position was marked on the Yardage Book Image. The Distance of these two Positions in Pixels is the Quality, which should be below 15.

Tap on New to start mapping a GPS Position manually. Read the instructions in the window popping up and tap on OK. Then, tap on the Yardage Book Image on the Position you want to record GPS Positions for. After that, you are presented a Dialog box to set the GPS Coordinates. The operation is identical to Playing - Recording GPS Positions. After you have successfully mapped the GPS Position you will find a new GPS Position named Untitled in the List Box.

Tap on Name to change the Name of the GPS Position selected in the List Box. In the Window coming up, enter the new Name in the Edit Box or select the new Name from the Combo Box. Tap on OK to confirm the new name or on Cancel to abort.

Tap on Delete to delete the GPS Position selected in the List Box. In the Window coming up, tap on OK to confirm the deletion or on Cancel to abort.

Top on GPS to measure again the GPS Coordinates for the selected GPS Position. The operation is identical to Playing - Recording GPS Positions.

Tap on Pos to reposition the GPS Position on the Yardage Book image. After the Tap, tap on the new Position on the Image, to abort the Repositioning, tap outside the Image.

Double-Tap on one of the Entries in the List to see the Details of the GPS Position in a new Window.

Tap on Hole Image from Google Earth to import a Hole Image from Google Earth for the Hole.

Tap on OK to confirm the changes of the GPS Positions or on Cancel to Abort. Once GPS Positions are mapped manually, you see a little Satellite Icon at the Spot where you added the GPS Position.
