Google Earth

I must admit I am blown away by this  Google Earth

Being a geography and atlas freak I enjoy physical topologies and all things related to maps. There is something magical to this software.  I will not be shy in saying that  this software ranks along with other category killers such as Netscape, Blogger, Flickr etc.

This will change the way people will think about the physical world. I can already imagine creative applications such as versioning piece of land to track environmental changes, real estate expansion, urbanization, urban design etc.  Hackers will keep Sunnyvale 1.0, 2.0,3.0 in some kind of source code control and will run diff on them to visualize urbanization !

This is way too  cool and I salute Google for giving this free  !
