I was curious as to how out of date googles photomaps are in the US and Europe. So I made these list of the top 10 cities by population and zoomed into the CBDs on google earth to determine the aerial capture dates.
US are on average ~14.1 months out of date, and EU are on average ~28.5 months out of date.
