[HOT] Offset error in the newly updated Bing Imagery

[Guttorm Flatabø]

Hi Amrit,

here in Norway we are well acquainted with poorly positioned Bing imagery.
And similarly to Nepal (I presume) this is a big problem in areas where the
elevation shifts frequently over short distances (in other words where it
isn't just flat). It seems Bing isn't really adjusting their imagery to a
digital elevation model. I have complained through Steve Coast who works at
Microsoft/Bing and knows who to contact, but it does not seem to have
helped. I'm hoping Mapbox will come to the rescue...
