Microsoft has unveiled its Virtual India Project, an online interactive map of India modeled on Microsoft's virtual Earth.
The map supports a resolution of 1:1M and 1:8000 specifically for Bangalore city. Standard features like tagging and view specific permalinks are included. Also included is a multi-lingual capability supporting English, Hindi, Kannada and Tamil.
The only spoiler could be your bandwidth, with the approx. 100kbps speed that my provider doles out in the name of broadband, it required a lot of patience to check out the nitty-gritty.
Find the online map here and more information on the project here.
