I've started a database of tracks with free LiDAR data sources. See https://docs.google.com/spreadsheets/d/1TC3ZEGzZtE7Ywmzf2UOlrZRaMbj_BOoIKkJHDtIPSpM/edit?usp=sharing If you have any sources to add, let me know! Tracks (last update 25 May 2016) Aintree Motor Racing Circuit Autobahn Country Club Baltimore Grand Prix Bedford Autodrome Belle Isle Blackhawk Farms Brainerd International Raceway (Donnybrooke) Brands Hatch Circuit Burke Lakefront Airport Cadwell Park Circuit Carolina Motorsports Park Charlotte Motor Speedway (Lowe's Motor Speedway) Croft Circuit Darlington Motor Speedway Daytona International Speedway Daytona Milton Keynes Denver Grand Prix Des Moines Grand Prix (historic 1989-1994) Donington Park Circuit Gateway Motorsports Park Goodwood Motor Circuit Greenwood Roadway (historic) Heartland Park Homestead-Miami Speedway Houston Grand Prix (Reliant Park, NRG Park) Iowa Speedway Kansas Speedway Las Vegas Motor Speedway Lime Rock Park Long Beach Grand Prix Lucas Oil Raceway (Indianapolis Raceway Park) Mallory Park Racing Circuit Mazda Laguna Seca Raceway Meadowdale International Raceway (historic) Miami Bayfront Park Michigan International Speedway (with historic road course) Mid America Motorplex Mid-Ohio Sports Car Course Nelson Ledges Road Course New Jersey Motorsports Complex (Thunderbolt Raceway, Lightning Raceway) Old Bridge Township Raceway Park Oulton Park Circuit Pittsburgh International Race Complex (BeavRun) Pocono Raceway Portland International Raceway Rockingham Motor Speedway Rockingham Speedway (North Carolina Speedway) Road Atlanta Roebling Road Second Creek Raceway (historic 1982-2005) Silverstone Circuit Sonoma Raceway (Sears Point) Snetterton Circuit Spokane County Raceway (Spokane Raceway Park) St. Petersburg Grand Prix Summit Point Motorsports Park Talladega Superspeedway Thompson Speedway Motorsports Park Thruxton Motorsport Centre
Updated list with Mazda Raceway Laguna Seca. I had searched for the data initially, but didn't find it and for some reason I found it this time... go figure!
That's lovely!!! I'll definitely take a look at this data as soon as I have a little time to fiddle with track development. Thanks Emery!!
IRL is visiting NOLA Motorsports Park, near New Orleans in April. NOLA opened in 2011, but most of the Louisiana aerial LiDar files date from 2005 timeframe. The one exception is a coastal scan done in 2013, but it covers only about half the track. Should I list it in my database even though the data is incomplete?
Link for Blackhawk Farms is down. Of course I find this data after I made the track for GP Bikes. Lol How are you guys using this data? Is there an importer for 3ds max? Just modeling over the top of it? GP Bikes track...
Nice looking Blackhawk Farms! Bummer. Timing is everything! On the surface, it looks like the Illinois Clearinghouse is shifting us into finished products rather than the raw data. You might try http://isgs.illinois.edu/nsdihome/webdocs/contact.html to see about the raw data. I'll see if I can dig up another link. *** Bob's Trackbuilder can be used to build a mesh from raw points. Export to rFactor (or similar), then use 3dSimEd to export the meshes into Collada for other programs.
Here's an index into the LAS files: http://isgs.illinois.edu/nsdihome/webdocs/ilhmp/county/dsm-dtm.html. Blackhawk Farms is in Winnebago County. It would be nicer if they left us access to the tiles so you don't have to download GB of data. You likely will want the ground return than all returns.
Updated database with links to Google maps aerial photos for the search impaired. Illinois Clearinghouse link has been updated with link to LAS files and I'm asking them if there is still a link for individual tiles rather than whole counties.
Thanks Emery. When I saw it was a 37GB file I would need I lost interest quickly. It's a pretty flat track so Google maps would suffice I suspect. But if LiDAR was feasible it sounded neat.
The answer from Illinois Clearinghouse, paraphrased, is "download the County's LAS or TIN and extract just the tiles you need for your project". Harrumph.
Why all the regional links? Use http://lidar.cr.usgs.gov/ and the Earth Explorer to just crop out only what you need. For BHF, it was 4 files about 6.3 MB a pop.
Thanks! At the time I compiled the list, a lot of the regional data(*) were not available at USGS. Guess I'll spend some time double-checking. (*) Quick spot-check still shows Brainerd scan, for instance, is not available at USGS. Not even all of the Illinois data, like Autobahn, is there yet.
Just had a peek at the USGS page. I think next time I get a few spare hours I'll start the 37GB download, and the USGS registration process at the same time and see which one I can get done first. LOL. You'd think they're trying to collect my data and monitor my every move...
Check the first post for a link to my database and you can download LiDAR data for many tracks, more than any single person will complete for rF2 in their lifetime. The USA is a big place and only a fraction of it has been covered by aerial LiDAR. The scanning happens at many different government levels (local, state, & federal), so there is no single-source. What I have done is searched around to find what tracks have been covered and what sites have the data. Federal sites are easiest to use (NOAA and USGS), but not all the scans are compiled in those two sites. This is a different situation compared to Holland, where a single agency has scanned the entire country. Holland is smaller than most states in the USA. I know the site for Holland's LiDAR files, but I don't have an index into the files, so I haven't figured out which file(s) would show Zaandvort (sigh).
