@RomGuyony. Yeah, I noticed that as well. Ijust took a lap at Daytona following the yellow lines, and sometimes my dot was out of track, sometimes in the middle. Maybe the track actual centerline doesn't match the map centerline.

Using 16 ft I got the following results:

1193.92 m  - offseted from the inner line

1172.21 m - offsetted from the outer line

-

Still, not the best results. I repeated the procedure for Hockenheimring. While Brands Hatch would have been much easier, it have only a couple of left hand turns.

Hockenheimring

Outer: 4578.31 m

Centerline: 4558.25 m

Inner: 4539.38 m

Wikipedia: 4574 m

I really don't think extracting data from these maps will be very useful after all. Still, they will be really nice for producing our own track maps. I'll work on one when I have the time.
