[Talk-GB] New Bing Imagery

Wed Aug 19 10:06:37 UTC 2020

For what it's worth, I feel like Bing has less offset overall. A lot
of south London has been aligned to the previous Bing imagery which is
almost certainly worse than the current Bing imagery. My impression is
that Bing is "more correct" than most other imagery sources.

Unfortunately the levels of error we're looking at are approaching the
margin of error of most GPS receivers, so GPS tracks, while sometimes
helpful, are not the solution to this either. As Alan says, OS
StreetView is probably the best reference in most cases.

The new Bing imagery seems to have less offset from StreetView in most
cases, but it does still have offset (and often in the opposite
direction from the old Bing imagery...).

Cheers,

Russ
