Mapquest's aerial images are about 3 years ahead of Google's images for my place.

I paid a local aerial photography company $275 to take pictures for me. That was 2½ years ago. I gave him GPS points and a street address and he provided about 30 high resolution digital files. He even made sure to ask if there were any special areas of my property I wanted him to get. I wound up having the best shot printed out on 24"x36" paper for a "before" shot. I'll probably hire him again when the new house is built.

I checked online for aerial photo businesses near me. 1 or 2 others were around but this guy was reasonable and he gave me the files. Others charged for their service and provided a few pictures but they either charged extra for the digital files or would not provide them at all.
