The problem is also with the scale because the UDP coordinates are in meters
Wait, as the coordinates are metres, can you not just go to each straight and move in a straight line, use the lap distance from lap data packet and use the in game track map to compare original and final position. Example: you move in a straight line, take a screenshot of the track maps, before and after, then find the amount of pixels between the before and after image of your location, then use that to work out the scaling.
Let's say you move 200 metres, the difference between your dot in the 2 images are 200 pixels, and the box from the OSD is 1000 pixels then you know 1 metre is 1 pixel and the entire box is 1000 metres x 1000 metres. This is a simple example but the process should work the same.
