[OSM-talk] Problems in Chittagong, Bangladesh

[Dave Stanley]

Thanks for the advice.  The Bing image does appear to be spot on.  I 
have started having a tidy up and will continue when I can.  Most of the 
GPS tracks will be from me in that area.  Unfortunately I only travel a 
few routes for my work.  I am moving on to another city now, so I will 
see what has happened there.
