    First, I have to say that smogbike made an amazing work with the info and tools available more than 10 years ago, because the spirit of the track is there. But then, if you have the tools and information to correct the "mixtos" part of the track, it will be very appreciated, because it was the most technical part of the track and sadly it's the most different from the reality. Not just the layout, but the altitude of the mixtos and the fall through the "tobogan" were always too abrupt.

    Try to do it more accurate, and it will be used many many years more.

    I can't wait to see lot of fast Porsches at Saloto ;)

    Ciao Rik!

    Sketchup/GE elevation are not a good reference, at all. That's a very cheap and, most important, wrong source for vertical alignments.

    First of all what Sketchup it's importing has been grabbed straight from GE database, in a bad form as it can just work with limited terrain resolutions per quadrant and its also depends on scan/grab @ altitude. Considering GE is already using pretty low GRIDs/DEMs (depends on the region but GRIDS are usually 90mt/30mt/10mt), what you are seeing there it's a too cheap surface to build a track on top of it...but this is not the first motive I wouldn't use a GE GRID as a reference;

    A modern racing track is NEVER ground level. Engineers/Architects are "modeling" that bare ground to create proper elevations, and these layers are, 90% of the time, NOT in the GE terrain models.

    To build a track they are removing soil to do depressions, they are adding more to create elevations, cambers, embankments, crossfallings, banking drainage etc...

    What you see in Google Earth is just bare ground model, basically a low resolution mesh which represents how the "original" ground was, without the track.

    You can easily understand this checking Atlanta Motorsports, or Mores...or whatever "modern" track you want.

    Only very modern scans, exporting DSM (surface model) instead DTM (terrain model) are good enough to build a track but they are not available in GE. They are usually in the form of raw aerial LIDAR data (see Mario Morais wip tracks) or DEM/DSM available in local GIS database.

    Also there is another problem related to Google Earth sat/aerial maps, used as a Ortho reference to build a track; here too we have a problem related to geo corrections (earth is not flat as a ortho map) and terrain elevations to Ortho image projection are not cleared from vertical distortions.

    This is why all Spa version you see out there, based just on GE, are all WRONG. :)

    Said that I would not redo the track flow using those Sketchup terrain models...:p

    PS: those terrains are pretty good to build outer scenario, with hills, mountains etc..in the form of low poly and/or TIN.

    Grazie Tuttle.
    In that way I do not lose time unnecessarily. I could not find lidar points for Villa Riachuelo or Autódromo Juan y Oscar Gálvez.
    I try with data dem. Today I signed in the USGS site. I have to understand how to work with them. If someone wants help to have a plane elevation. He is welcome.
    Thanks again

    I'm trying to find sources for take more real data. stay tuned. I wrote to Lidar Argentina. I hope they will respond to me.

    Good news: i have some real point data for track. i have redesigned track spline with those new ref points.
    there is a issue but i don't know if it's real issue.
    my central spline measure km 5968 and it match with various web site but in Wikipedia the track lenght is km 5948.
    look

    Yes, I know, had to check it anyhow. GSCE has an excellent version of the track, so it could be used as a reference.

    Tried this track and had to uninstall, jagged edges all around edges of track, guard rails are glowing red, where they should be white, not optimized for DX11 yet ?

    Great conversion! Anybody knows what tracks from 79 season are available now for rf2 (except kyalami, dijon, buenos aires, silverstone 75 and jarama)?
