Jai Hind "ISRO Bhuwan"

News

paper articles were flooded with the "ISRO Bhuvan" and it was quite annoying for me to see the same term everywhere in my feed reader as well. Finally I had an eager to know, what exactly ISRO’s Bhuvan is? The answer to this question was quite interesting.. I came to know that Bhuvan is a competitor for Google Earth and would provide services similar to Google Earth and Wikimapia but it will be confined only within India.

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 official sites and 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.

SO See is it better than google earth ?

JaiHind ...
