@Garry Mc: I wrote an update to this post five months later after Google introduced rooftop geocoding to, at the time, 50 million addresses in the United States.

Check out Google agaiin, I tried it with a few address I know from around the world and it seems more accurate. I also tested the address on the image here and it too is now spot on!

Google has improved in the past few years, so retest again!

Google Maps and Virtual Earth both use WGS 84.

Hi,

During test, did someone make sure that all the coordinates are using datum. MapPoint uses WGS83 as a datum and I am not sure about Google. But what I know is that you observe lot of error if try to plot coordinates that are based on NAD27 on a map that uses NAD84 dataum. Well, I don’t think anyone uses NAD27 anymore, but some error might also come even if one service is using WGS83 and other is using NAD84. Just few ago, I wrote a blog about this. Checkout

That is a pretty good rendering, not to mention a very cool photo on your part.

It's amazing the accuracy of Microsoft's 3D imaging as well. I compared a photo I took in Montana with Microsoft Virtual Earth's rendering of the same view. See for yourself!

Thanks for the link to Miami’s Virtual Earth-powered mapping app. Pretty impressive work!
