Geo names translation

Working for international institutions and for international projects I have to write in English some Belarusian geographic names. I used to be a nightmare to think of the best transliteration. But it is not the case any more. There are two documents which give the guidelines. First one is issued by several Belarusian ministries (see here - in Russian) and another one is the Belarusian document submitted to the UN (see here - in English). Sometimes there are good improvements ;)
