Did using classification not work?
You can separate out road
with 11-11 filter pass.

Remember you've got a crutch in that we know the track width. T3 is 30 ft wide (9.144 meters). You also know that the corner radii are always constant on this track, so you can use circles as guides for the splines. Can't quite recall the geometry trick for finding the center of an arc though...
Edit: and Amir is right... use the lidar when points are classified!

I messed around with the classification filters and still couldn't see a clean road outline. The .lax files are in the Google Drive if you want to take a look and try to extract a good road image.
Also, where did you find the data for the turn track widths?
This is one of those cases where you heave a little sigh because the points aren't properly classified. This data is also from the early period of aerial lidar, so the points are not particularly tight
With classification not helping, you have to rely on intensity and even that isn't going to be particularly helpful since packed gravel and pavement can be pretty similar in intensity. What I like to do is switch to colors for the intensity and see if I can tune out the gravel in Cloud Compare... wasn't all that helpful for track width at Brainerd, but just to document the process.

- Select Intensity as the active scalar field.
- Select Blue>Green>Yellow>Red for the Color Scale
- Slide the right hand limiter back & forth for the display limiter to see if there's a helpful setting.
To check how far apart the points are, you can zoom in. You'll notice horizontal bands and also where the two flights have overlapping data. Vertically, you'll notice larger gaps between the scan lines than there are horizontally. Using CloudCompare's point picker, you can measure how far apart the points are (about 1.8 meters vertically and 0.8 meters horizontally).
Here is the T3 exit, where the two scans overlap. The top road is an inner access road, probably compacted earth and gravel.

@LilSki 's video (on the left) has a "corrective smooth" deform option in the modifiers. My modifier list is on the right. I assume the difference is 2.79 vs. 2.8 and that I should choose "Smooth Corrective?" I'm going to use this to flatten the bridge so my shrinkwrap modifier on the splines doesn't make the track crest over the bridge.
^yep.
2.8 is smooth corrective.

Hey man I'm interested in doing a track with yah I'll help out I work second shift tho 2 to 10 everyday but I can put in hours I previously.made maps on Cs go a friend's map for his game Delta horizon (crashed and burned lol) and the socom mod for insurgency and Cs go) messed with unity, unreal engine, and race track builder. Hit me up on steam account is either Hylianlink15 or Falken should have a blue bear as the icon
PM sent, thanks for your interest in working on the track!
I think that a forum thread (whether it's this one or starting a new one) might be the best approach for communicating. We've communicated through PMs, this thread, and started a Discord. The Discord (which @elloLeo Kinnunen set up for us) would be good for when we want to voice chat.
I like the idea of a forum thread since other members can follow the progress and it could stand for years afterward as helpful to other track builders. Thoughts from @Hyrulianlink15 , @elloLeo Kinnunen , and @Emery ?
And I'm hoping to follow @LilSki 's videos (he's currently uploaded 3). My current obstacle is getting a clean mesh between the track splines. I've laid out the inside and outside edge of the track with splines in the Blender file (and I'm not convinced that even those are adequate), but my attempts to shrink wrap and get a mesh between them to continue with the tutorial have horrible geometry. If you want to take a stab at that after you get the Google Drive permissions, that would be ideal!
I'm at work ATM but I used to use a program I don't remember what it was called where we all could access it and set up things we want to work on and have worked on
It's called trello
On the research side, I've been gathering pictures. Of the 22 pit buildings, there are now pictures of 18 of them. On the project share, there's an aerial view with the bldgs labeled and a folder structure corresponding to the labels where the pics are located. There is also a Google Sheets document with dimensions for the buildings. I've begun modeling bldg D, the Tower Suites, that overlooks the dragstrip because it is so prominent.
Did your book arrive yet? I've been watching an onboard from the hood of a Cayman (below) that has more field of view than most in-car onboards that will be helpful with some object placement. Even nicer that there's a track map overlay in this video:
There was a snafu. Will arrive next week.
