But there is something special in Bhuvan that keeps Google Earth and Wikimapia aside. Bhuvan will have a greater zooming efficiency that will help you recognize details upto a 3 storey building and all its data will be updated every year, unlike Google and Wikimapia which updates in every 4 years.
As per an article in TOI:
Bhuvan allows you to zoom far closer than the aerial view from a chopper. If Google Earth shows details upto 200 meters distance and Wikimapia upto 50 meters, Bhuvan will show images upto 10 meters, which means you can easily see details upto a three floor high building and also add information.
It has also came to light that, unlike others, Bhuvan will support multi layer viewing with a option to view on past dates. Finally I would feel proud to say that Bhuvan is going to use Indian satellites. 🙂
Also, at the Indian National Cartographic Association (INCA) International Congress it was said that:
The prototype of Bhuvan will be ready by the end of November and ISRO is hoping to officially launch the service by March next.
So, we will have to wait for another couple of months to see it live. 🙂
