Why not ask your question on the new OpenStreetMap Community Forum?


Using the aerial images of Microsoft / Bing is a great new development which will increase considerably the speed with which white spaces on our map can be filled.

However, it would be interesting to know how old these images are. I know that the Yahoo imagery is quite old for some parts of our globe and this can cause problems if areas are drawn without local up-to-date knowledge. Therefore, it would be nice to know how old the Bing imagery is.

Try the interesting tool: Bing aerial imagery analyzer for OSM

As you zoom in the dates change for each zoom level.

Very nice web service!!!

Is this available for the whole planet? And already mentioned in the OSM wiki?

The Bing images are sourced from different providers. Some are more current than others. If you have an image URL of, say


You can retreive the HTTP headers using a browser plugin or an Unix commandline tool like

$ HEAD 'http://ecn.t3.tiles.virtualearth.net/tiles/a1202022331312023.jpeg?g=587&mkt=en-us'

This will return, among other things, a line that reads

X-VE-TILEMETA-CaptureDatesRange: 6/17/2006-7/14/2006

Which tells you that this specific tile was created from an image taken about 4.5 years ago.

OSM editors don't currently show that information but I assume that in the long run, ways will be found to make it readily availalbe.

For example one can use http://www.askapache.com/online-tools/http-headers-tool/ - just paste any URL into the Target URL field and you get all response headers.

In your browser's Developer Tools "Network" tab you can see the headers too.
