Last month [bing.com] we pushed out our largest amount of new imagery EVER in terms of square kilometers. This month, we’re blowing THAT record out of the water. You thought 1 million+ sq. km. was large? How about 6.7 million square kilometers! It’s pretty much unfathomable. The big winners? Aerial: The Russian Federation, Australia, Mexico and most places in the US where we had black and white imagery.
Still, at least where I need it, Bing does a bang up job. Google (just to mention one) hasn't updated their photos in this area for close to two years. Bing's stuff is less than a year old and much more clear.
(Gad, I mean, it's free and here I am whining about G's pics, which are great. I hate doing that because I have had it done to me so often. Provided apps that did MAGIC--amazing!--and two weeks later, everyone yawns. This is a tough, tough biz.)
