Google Earth, maps and local

[tenchi-fan]

I used google local and thought it was cool. I does a good job at zooming into where I work and where I live in Dublin, and the map overlay was accurate. (Too bad it doesn't contain detail for Dundalk, apart from a blurry aerial photo)

I assume google maps uses the same information as google local?

And is google earth just the photograph part of google local? (I can't install it on my PC at work to try it out myself)
