GNS however is a valid source...
http://earth-info.nga.mil/gns/html/index.html
The country file for russia is 28MB zipped (83MB unzipped) with 547909
records...
It's supposed to include a PC field for importance level, but, it doesn't
seem to be populated in the Russia data, also, supposed to include
population, but, that's also missing...
I modified my GNS extract script to interpret the data and merge the russian
cyrillic and local latin names into a single record... about 99% of records
have a latin format name, about 50% have cyrillic (judged by eye)...
I'm just looking at mapping the correct feature types and looking at the
possibility of matching administrative records to populated place records in
an attempt to calculate place size...
e.g.
Place with no indication of type of place
4 -3003991 6879674 56.851944 41.362222 565107
412144 37VFD4405303392 NO37-12 P PPL RS
21 NS rus ШУЯ
Шуя Шуя 2007-02-12
4 -3003991 -4209549 56.851944 41.362222
565107 412144 37VFD4405303392 NO37-12 P PPL RS
21 NSHUYA Shuya Shuya 2007-02-12
and
Admin level 2 object mentioning it's a city...

Perhaps it might be best to just use the ADM objects rather than the PPL
objects, but, you can't get smaller places then and the ADM objects tend to
be placed further from the center of a place than the PPL objects...
