Hi All, I just wanted to let you know that I've completed the import of buildings in wards 67, 68, and 69. You can see it at http://www.openstreetmap.org/#map=15/23.7158/90.4053
There are some areas where I've left some minor roads overlapping with buildings during the import, and I apologize for this. Over the next two months we'll have teams of surveyors going over the area, correcting these mistakes, and mapping in greater detail. Cheers, Jeff On Mon, Aug 12, 2013 at 7:03 PM, Jeff Haack <[email protected]> wrote: > Hey guys, > > The data is of quite good quality.
