Bhuvan, which means Earth in Sanskrit, is a satellite mapping tool from Indian Space Research Organization (ISRO) that offers resolution of up to 5 meters and is considered as a rival to Google Earth and Wikimapia. The new application provides a mode to explore and discover virtual earth in 3D space with specific emphasis on Indian region. Its prototype (beta) was launched on 12th August 2009.
Bhuvan goes one step ahead from its rival as it give you an easy way to experience, explore and visualize IRS images over Indian region. The application allows users to zoom far more closely than the aerial view from an aeroplane. It uses images taken over a year by ISRO's seven remote sensing satellites, including Cartosat-1 and Cartosat-2.
Basic features of Bhuvan:
1. With the new application, users can access, explore and visualize 2D and 3D image data along with complete information on natural resources. 2. People can visualize multi-resolution, multi-sensor, multi-temporal image data and also superpose administrative boundaries of choice on images as required. 3. User can obtain AWS (Automatic Weather Stations) data in a graphical pattern and also able fly to selected locations, which means you can navigate freely using the mouse or keyboard. 4. The application features various navigation controls for example Heads-Up Display (HUD), Tilt slider, north indicator, opacity, compass ring, zoom slider. It supports navigation via 3D view Pop-up menu. 5. With the help of Bhuvan, a person can draw 2D and 3D objects on the application and further he can create its snapshot for later references. It also provides various measurement tools like horizontal distance, aerial distance, vertical distance, measure area. 6. The new tool has some special features like shadow analysis, which uses the Sun’s position at a given time creating shadows and effects the lighting on the terrain. ISRO announced that the application will have more value added functions and facilities which will be added into the package from time to time.
Future Additions in the Application:
The motto of the institute and the department of space would be to provide such functionalities to common man so that he adopts participatory approach with scientists to solve simple problems easily and interactively. In future versions, we can see some of the advanced functionalities like: • Urban Design Tools for infrastructure settings • Contour map to distinguish different terrains • Terrain profile for minute details • Draw tools for urban designs • Navigation map to view exact locations in the 3D India
Bhuvan: Fulfilling India’s ambition
Bhuvan, which is based on TerraExplorer software a product of Skyline Software Systems, is an ambitious initiative to showcase India’s distinctiveness of Indian imaging capabilities to provide vital information for common man with a focus on Indian region. ISRO is utilizing the benefits of India’s Remote Sensing satellite system, which has currently 9 operational satellites in orbit - IRS-1D, TES, Oceansat-1, Resourcesat-1, CARTOSAT-1/2/2A, IMS-1 and RISAT-2. Also, with new additions in the space, the Indian EO system is expected to provide new products and services enabling applications in several areas spanning from cartography to climate.
