You an get the rough base for the track very easy, then it would be a case of a better res image which is do able.
Thats also the elevations so not just flat, although it looks like a flat area of America.
What he can get is the proper scans, but essentially its the same process, he'll have that base but better quality in 20 mins max, then its adding objects, job done.... I've done about 5 tracks this way, and one using photogrammetry.
His Newcastle motor park track you literally are driving on the satellite image, the road text and everything, it looks bloody fantastic.

His Newcastle track, i'm not saying its a bad thing, but he isn't modelling tracks in any sort of traditional way.

A photogrammetry track im in the process of tidying up, but its all there and all the hard work is done by the photogrammetry.
