ISRO launched BHUVAN

A new mapping application like google earth on wednesday. The day marks the 90th birth anniversary of the father of Indian
space programme Vikram Sarabhai.

NRSA scientists developed the content using data provided by
Indian satellites like Resourcesat-1. ‘Bhuvan’, which in Sanskrit
means the earth, also focus on rural and thematic applications like wasteland
mapping and terrain profile. It contains weather details like humidity levels. Space officials requesting anonymity said viewers can zoom
into ‘Bhuvan’ maps up to 10 metres compared to Google Earth’s
200 metres and Wikemapia’s 50 metres.

"Bhuvan" will use images taken by ISRO's
seven remote sensing satellites at least a year ago. These eyes in the
sky can capture images of objects as small as a car on the road to
build three-dimensional map of the world.

‘Bhuvan,’ the new web-based 3D mapping tool uses images taken
over a year ago by ISRO’s seven remote sensing satellites, including
Cartosat-1 and Cartosat-2. The satellites can capture images of objects
as small as a car on a road.

The degree of resolution showcased is based on the level of
popularity of a place or an area. Most of the terrain is covered up to
a resolution of at least six metres. The least spatial resolution is 55
metres.

Google Earth shares
only single layer information, its Indian counterpart would share
multi-layer information using the images exclusively from indigenous
satellites. The images would be visible to the user both in two and
three dimensions using the navigation tools provided. An additional
feature provided by Bhuvan would be allowing the user to scroll through
the newspapers of selective cities across the country. As much as 16
cities across the country are available in the portal to share their
news. The user can zoom on to the city of their choice to go through
the local news.
