Jorieke might have a different opinion and his is the authority :) but
it looks to me like the new nextview imagery is better aligned than
bing. I would use it as the main georeference. In addition most things
will be mapped with Nextview so might as well keep them all consistent.
How did I come to the NextView is better aligned conclusion?
visit this spot in JOSM:
https://www.openstreetmap.org/#map=19/23.750183/90.368716
And load the bing, nextview and "OpenStreetMap GPS Traces" (JOSM Imagery
Preferences again, select up top, use the arrow in the middle to move it
to the bottom list)
It is a divided street, you will see Bing has traces going off the side
of the road and down the middle of the trees on the divider, the
nextview imagery has the traces nicely on each side of the divider on
the streets.
Hence, to me it looks like the nextview is better aligned.
Again, Jorieke would be the authority.
Hope that helps.
cheers,
Blake

Hi HOT mappers!
Next week HOT will start mapping "in the field" again! Under the
umbrella of the Missing Maps Project we will map some neighbourhoods
of Dhaka, the capital of Bangladesh.
We have mobilized the local Bangladeshi OSM community and they are
ready to collect local points of interest, names, ... Pete Masters
(as coordinator of the Missing Maps Project) and I are going to
support the local OSM-ers.
The local community is mapping already, but the help of the
worldwide mapping community is welcome to help to prepare the field
survey. Last week there was a mapping party in London, and they did
a great job, but there is still more work to be done...
It would be great to have a (rough) basemap of Hazaribagh

next saturday. The areas are two very vulnerable neigbourhoods in
Dhaka where a lot of ngos are active.
So for this we count on your joint forces!
Mapping tasks:
- http://tasks.hotosm.org/project/838
- http://tasks.hotosm.org/project/831
Validation task:
- http://tasks.hotosm.org/project/833
But watch out, these are not easy tasks, because the areas are so
crowded. I made a small presentation on how you best can map the
areas. You can find it back in the instructions of each task.
Looking foreward to see the tasks moving :-)
Best greetings!
Jorieke
