KMZ

I am really anxious to see more government agencies providing GIS information in KML format. The potential for reuse and leveraging of this format is huge. I may have referenced this before, but I think that the Utah Geographic Survey continues to improve what they offer such as this file. And you can view in multiple tools, including Google Maps and Google Earth.
Speaking of maps, I am really quite impressed with Yahoo's new beta of India. It still has some issues, including slow reaction, but the resolution is pretty good, as you can see from this image of Salt Lake stadium in Kolkata. The map includes a Bengali language option. Utah has been working to strengthen economic ties with India and this map is a great resource.
