Comment from Dalkvist
Please note that the new images from digital globe often is offset and warped, not always as obvious as this http://i.imgur.com/7ppH5jN.png ;)
The imagery from Bing is seldom offset or warped so trust that before dg and always trust the gps traces above any imagery.
In this area dg looks to be 4-5m to far east.

This is how it looks in JOSM - GPS and Digital Globe. I also sometimes switch to the control on BING (but seems to have deviations).
GPS may also vary, especially in the forest and mountains. I think it is cheaper to map the aerial photo, since then buildings and terrain also fit relatively.
