Hi Yadgar,
No, the images do not follow the Earth's curvature. The elevation data 
as provided by the state government here is set up as "flat" tiles which 
can be stitched together.

I haven't tried pedestrian views having gotten distracted by other 
things, but it is on my list to do. I have the idea to do it in 
combination with the SkySim macro for the sun & sky on some give day at 
my position just to see if things match up!
