    I have a quick correction. Based on your videos when you were going over the LiDAR data, you pointed to the road that runs alongside the current Dos Equis Pavilion (concert venue to the southeast) as part of that back straight, and then it cuts into the parking lot about haflway down.

    That is all incorrect. Where the pavilion currently is was a big parking lot at the time (The venue opened in 1988), and that back straight with the mid-way chicane was straight away into the parking lot (and there's a slight kink before the chicane). The track never went on that road at all.

    I've got a pair of 4k exports from Google Earth from 1995 and 2001, and I've added a track overlay to the 2001 map that is (as far as I can tell from the video of the race) completely accurate (with some estimation on that back chicane location, it's somewhere on the lot where the Dos Equis Pavilion currently is).

    Maian, your images are really good, and your track layout is very well done, I was wondering how did you make that ?
    I made a slight correction to it however, as after a lot of analysis, the 2nd chicane was located a little shorter to where you indicated, and the 3rd chicane on the back part, was almost right in front of where there used to be a roller coaster, so something like this:

    And you can glimpse where that roller coaster was:

    You're right about the chicane near the roller coaster, I just couldn't ever find an image of that chicane that looked in towards the fair grounds to find its relation.

    So, for the portion that runs through the parking lot to the Southwest, along 2nd Avenue, if you look at the screenshots below, it helps guide where the track went. I do have a slight correction on the entry there, though. Screenshots are around the 18:30 mark of the race video, when the commentator starts talking about emergency tire changes from a couple of teams.

    The part about that last wide turn (Turn 12? Leading into the back straight next to Pennsylvania Ave) can be seen at 33:55 of the race video. As they make that turn, if you pause, you can see the curb line cut in harder than the track. Then as they move up the straight, you can see the median between the lot and Pennsylvania Ave to the inside of the track. When they get to the chicane, you can also see the big light poles that are just to the inside, and the grandstands just after are to the left (in the image above) of the grassy parking lot split.

    The on-board video also shows the little kink I have drawn just before the chicane.

    I have one question: where the hell where you when I did this 10 years ago for F1C ? You would've saved me months of visual research !! Anyway, here's some more images to add to the visual puzzle, these will probably help you out to make an even more accurate layout map (which is great by the way!) Thank you for your very positive help :)

    Oh and by the way, another thing that is unclear for me is that double/triple apex left curve that leads into that straight, if you’ve got a good idea, I’m a taker!

    Looking back at your historical aerial photo linked, it was just dirt and grassy fields next to Pennsylvania Ave. The topo there is probably more along the street itself (so don't base it on the parking lot levels in the LiDAR file - they would've been re-leveled for parking). Just pointing it out because it changes what I thought the references were in that area. I was trying to fit the straight-chicane-straight to a parking lot, but those were paved for the concert venue.

    I'm trying to figure out how that long turn is laid out, but it's tough since I can really only find video of that specific corner, and no external images. I can kind of estimate, based on the alignment of that straight through the parking lot with the existing building in the back (you can see the windows in the first two images). That leads me to think the road is pretty much in the spot I have shown. It's also ~30 feet wide, based on the width of the Lotus, and measuring pixels.

    You can also see the cameraman in the top right image, on the scissor lift. Knowing that, you can kinda use the bottom two to figure out his exact location (the bottom right is a power pole that is on the corner of the lot and 2nd Ave that is still there today), and then try to figure out the exact layout of that turn. I assume he's lined up with the center of that straight.

    Just to show you the last thing I did on Dallas that was driveable was for rF1, shows just how much I’ve progressed in a year and a half:
