I do not believe that one can add reliable tracktype=* information from satellite imagery without having some ground truth knowledge in order to know how to interpret the imagery in that region.
I think that "without having some ground truth knowledge" is the key part there. I know from personal experience that if I was to try and add tracktype or detailed surface information based purely on imagery I'd get it wrong lots of the time. Very often when I'm updating OSM I'll add the details that I recorded while I was there, and look at what they say and what it looks like on the available imagery and the two can be very different.
