Bing is a search service from Microsoft, which includes the 'Bing Maps' platform (previously 'Microsoft Virtual Earth'). The platform includes map tiles, map embedding APIs, routing, and so on. It makes use of proprietary datasets, often licensed from third party geodata providers, and its use is therefore bound by copyright restrictions… however:
Bing Maps are investigating working with OpenStreetMap in various ways:
Bing Aerial Imagery
In November 2010 it was announced (, ) that Bing has granted the right to trace from their aerial imagery for the purpose of contributing content to OpenStreetMap. Please note the only legal use of Bing maps is to use the aerial imagery layer as background to do your own OSM drawing (also known as "tracing"). It is not legal to use any other information from Bing maps (like street names, street view etc.).
- For more information see Bing license.pdf.
How to use in the editors
- Most used editors (sorted alphabetically):
- iD – Opens with bing by default, but you can select 'Bing aerial imagery' in the layer picker icon on the right
- JOSM – In the 'Imagery' menu, select 'Bing'
- Potlatch 2 – Opens with bing by default, but you can select 'Bing' in the 'Background' drop-down. There you can also switch off the brightening.
- Other editors:
Coverage and age
The coverage of high-resolution imagery can be assessed using this tool. You have to zoom in to zoom level 14 or more to discover high resolution tiles, which will then result in green and red tiles indicating availability of imagery being rendered in all zoom levels. See discussion.
- See also Bing/Coverage to find out and help document areas of available coverage.
Be aware that at lower zooms, Bing's imagery may be misaligned. I.e., alignment is not consistent across zooms; at one zoom, you'll be aligned, but another, you'll be misaligned. This is different than other image sources, including Yahoo, which if misaligned tend to be consistently misaligned irrespective the zoom you're using. This is true of various places worldwide.
Areas with height differences (mountains, hills, bridges) seem more prone to this, which suggests that imagery was not always taken at a precise 90 degree angle. As a result, objects at the same height (ground level in a flat area) may be quite precise while objects which are higher (embankments, bridges, buildings) or lower (cuttings) may be slightly off.
Use GPS tracks, other OSM data you know is aligned, or other aligned imagery (if available) to align the imagery in a local area.

- True Offset Process - ideas for building a database of correction offsets
- Use tools such as Quadmap Compare or BBBike Map Compare to visualise side-by-side several maps and detect offset errors (use it as a error detection tool, not for correction).
2012 censorship of military areas in Germany
In the end of January 2012, Bing blurred many military bases in Germany after being asked by the German government to do so. The polygons of these areas were given to Microsoft by the German government. It is suspected that these polygons could have been exported from OpenStreetMap, since several blurred areas are perfectly matched to landuse=military polygon.
