Went to the track last weekend in Mettet, Belgium.
Used GPX data from my racebox mini to get the racing line of my fastest lap, which was a 1:20.22. The racing line is what you see, it differs slightly from the official track layout as the racing line is obviously not in the middle of the track throughout its entire length.
used a topgraphy extruder program to get the height difference accurate to the micrometer.
