Bhuvan will use a network of satellites to create a high-resolution, bird's-eye view of India – and later, possibly, the rest of the world – that will be accessible at no cost online and will compete with Google Earth. If a pilot version passes muster, Bhuvan will be fully operational by the March. There are also plans to incorporate a Global Positioning System (GPS) into the online tool. Bhuvan will mainly focus on the sub-continent.
Bhuvan has an edge over Google Earth. Bhuvan has a lot more features than the famed Google Earth. Lets compare Bhuvan with Google Earth.
- Google Earth zooms in upto 200 meters, Wikimapia zooms upto 50 meters but Bhuvan can zoom upto 10 meters. The image is of a very high resolution such that you can get a view from the three storey building.
- Google Earth is a single layer information whereas Bhuvan is a multilayer information.
- In Google Earth the images are upgraded every 4 years whereas in Bhuvan, it is upgraded every year.
- Google Earth has no alternative viewing option. In Bhuvan you have an option of viewing on different dates.
- Google Earth uses international satellites for mapping but Bhuvan uses Indian satellites.
The prototype of Bhuvan will be ready by the end of November and ISRO is hoping to officially launch the service by March 2009.
ISRO is now booming itself since the launch of Chandrayaan.
