[Talk-bd] Bing and road classification

[Larry O'Neill]

Hi All,

It has come to my attention that some of my links in these emails arent
working depengin on what DNS resolver you are using, so expanding these:

The relation marking out the hires imagery areas:
http://www.openstreetmap.org/?relation=1360344
Detail of the impact of Bing imagery in Ireland:
http://www.openstreetmap.org/?lat=54.03&lon=-7.497&zoom=10&layers=M
My recent changeset near Mymensingh:
http://www.openstreetmap.org/browse/changeset/10721820

Let me know if these fail!

Larry
