Comparing the On-Line Map Giants
A frequent topic of conversation among State GIS Coordinators lately has been the relative merits of the big names in on-line mapping.
As in: "What aerial imagery does Google have for my state?"
It's not an idle question. For much of the public, the web-mapping that has come into vogue in the last year is a first entre into GIS and spatial data.
Now, there's Flash Earth, a very simple flash-based interface that allows one to zoom to an area and click between the versions of that area found on Google, Microsoft VE, Yahoo Maps, Ask.com, and others.
As a result, I can now say with some confidence that Google has the most up-to-date imagery for the resort area in coastal Delaware (where I live) of all of these sources. Your results may vary.
Flash Earth describes itself as "an experimental application" and notes that the imagery is used "without official consent" from Google et al. Via LIFEHACKER

Interestingly, Ask.com has the most recent imagery for St. Louis, but like the rest, it is old. The St. Louis Metro Sewer Dist flys every year...but it never makes its away to Google or Microsoft. Tony
