I spent a little while the last two evenings using the new Digital Globe Premium Imagery for Turkmenistan to clean up some parts of Ashgabat plus areas in the far southeast I visited some months back but was unable to map in detail. This new imagery is terrific. I corrected some rail lines and added rail spurs to factories I either visited or rode past, plus added streets. This is good stuff.

How is the alignment in urban and rural areas of Turkmenistan in you experience? I found it to be generally much more consistent and less skewed than a lot of previously available imagery.

Claudius, I agree with you that the alignment is better, much better. Not perfect across all locales but much better. Where possible I collect GPS traces and make them public to ease alignment.
