I just checked a place where I had spotted a Bing offset before
and that disappeared. National aerial photos 2009 and 2012 are
offset by 2.8m. Bing is almost in the middle. But that's because
of a perspective effect. The national orthos have house walls
slanted by about 1.4 m for the house height and 2009 and 2012 are
slanted in opposite directions. The roofs are offset but they are
at the same position at ground level. That's of course very tricky
to compensate if one maps house based on roof contours. <br>
