The India Space Research Organisation has done a lot for the advancements of Space Research & Administration in India. ISRO created history by the launch of Chandrayaan. And it has established two main Space Systems: INSAT & IRS & has developed two satellite launch vehicles PSLV & GSLV to place INSAT and the IRS satellites in the required orbits.
Now, ISRO is up with Bhuvan to compete with Google Earth. “Bhuvan” is a sanskrit word meaning “Earth”. Bhuvan will provide services similiar to Google Earth & Wikimapia, but it will be confined only within India.
Bhuvan has some special features which sets it aside from Google Earth & Wikimapia. It will have a better zooming efficiency, multilayer viewing technology, and it will update its data yearly unlike Google Earth & Wikimapia which update their data in 4 years. Using the multilayer technology, we can see data from the past dates also!
According to a article at 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.
And the last fact, ISRO’s Bhuvan will be using indian satellites.
Here’s a table of comparison of Google Earth & Bhuvan from Wikipedia:
| Feature | Google Earth | Bhuvan |
|---|---|---|
| Max Zoom | 200m | 10m |
| Layer | Single | Multi |
| Update Frequency | 4 yrs | 1 yr |
| View | Viewing from only one date. | Options for viewing from different dates. |
| Source (Satellite) | Commercial/International | Indian |
| Imagery | World | World |
I hope to see this ISRO’s new innovation go live soon.
