He! Thanks for the flowers, but all I did was having a look at the format, finding out how the definition of the geometry works and how I could implement editing in TaxiDraw. The main idea I had for implementation was some kind of polygon offset approach, but in order to keep the variing heights at airports and not makeing them flat the polygons for the lines would have to be pre-calculated to fit the underground. At least one would need a clever way of quickly determining the plane in which the line segments have to be oriented. A dynamic texture-based approach might work, but it should really get it's LoD straight, as I don't think blurry taxiway lines are a good sight. The "blurry textures at low altitudes" might not be a problem when you're flying at typical altitudes, but I suspect it's a real PITA when your taxiing along.
