Unlike the other two, Bhuvan allows you to zoom far closer than the aerial view from a chopper. If Google Earth shows details up to 200 metres distance and Wikimapia up to 50 metres, Bhuvan will show images up to 10 metres, which means you can easily see details up to a three-floor high building and also add information.

Bhuvan will use the data recorded by the Indian satellites only. While other mapping sites take four years to update, Bhuvan will be upgraded every year. Unlike the other two webmaps, Bhuvan will focus only on the Indian sub-continent.

The information on Bhuvan will be layer wise and the options of viewing filtered information will be available. Inputs from a lot of local players, like farmers, fishermen and likes who know the local area in and out, will also being integrated in Bhuvan. This is for the primary reason to make it of more use to the general public.

All said apart, a doubt lingers in the corner of many minds that will Bhuvan also fall in the hands of terrorists, similar to what happened with Google Earth during the recent Mumbai attack.

However, such fears haven’t stopped any technology innovation till date, nor it would in future, after all every coin has two sides, which are never the same.

So, What could be next in line from ISRO? Any guesses...Nothing less than an unmanned mission to Mars in the next decade! So buck up India.
