Hi Matt,
In the context of the Bing Aerial imagery that was replaced, which was dated from 2010 to 2012, or 5-8 years old, the currency of the imagery has improved significantly. We intend to do this level of country wide updates every 1-2 years going forward. We also expect major metropolitan areas to be updated annually with other, often more detailed, products such as DigitalGlobe Basemap +Metro Imagery and/or Community Maps Imagery.
As was the case with the introduction of World Imagery (Clarity), we will continue to gather user feedback and requirements and present solutions to support variable use cases. In other words, we want our users to have options when it comes to what imagery works best for them.
I appreciate all of the interest and feedback! We will continue to post and discuss imagery updates going forward.
Regards,
Rob
