Is Red Planet for Iray an accurate model of the actual surface of Mars?

Thanks

    It doesn't have any "canals".  Otherwise, it looks just like it did the last time I was there.  Haven't been drunk like that in a long time!

    I can see what looks very much like Olympus Mons in some of the promo renders. It wouldn't surprise me if the content creator used some imagery from NASA as the basis for their texture maps.

    I found all the other major Tharsis volcanoes and Valle Marineris just from the promos. I can't imagine anyone would hand paint that so it is almost certainly the Viking mosaic image, which is copyright free although the PA should indciate that somewhere.

    Thanks bytescapes and kenshaw011267. That's what I wanted to know. Since it appears to be a real image rather than made up I'm going to grab it while it is still in FastGrab

    You can get DEM (Digital Elevation Map) data from NASA, I've done it in the past.

    It's... not easy translating it into a map, but there are ways. So maybe that's where the creator got it.

    (The big problem is that the really high end data is in a fairly simple text data format, I believe)

    for the curious

    (I've seen higher quality datasets elsewhere, but it's been years since I last looked)

    It is also available as a texture map: https://nasa3d.arc.nasa.gov/detail/mar0kuu2

    Is there gold in DEM hills?

     

    (sorry cheeky)

    Ha ha.

    I've been a bit... perplexed... in recent decades with respect to how quickly everything on Mars appears to have been mapped and named.

    Loved "The Martian" book and movie and -- for those who didn't know -- the guy published another novel, this one set on the surface of the moon.

    I have not used it for that, but I believe that the venerable Bryce can convert DEM data to height maps, IIRC.
