It looks like the landuses are shifted by about 28m at 126 degrees from
Bing z19 dated 05/08/2010-08/31/2010, but I don't have a ref for the
accuracy of Bing exactly there.
In this area:
south of Mojave airport, the landuses are shifted about 8m at 80 degrees.
They also appear rotated very slightly - maybe -1 degree. This is relative
to Bing z19 5/7/2010-06/21/2010. FAA runway coordinates at MHV show that
the imagery is shifted less than 1m from reality. At the interface between
the two sets of imagery (around 35.0024 lat), there is a shift of 0-2m
between them. Also, my and other GPX tracks along SR-14 also suggest the
imagery is accurate.
So, it's not clear why some of the landuses are shifted by so much, while
others are not.
