In what appears to be a challenge to Google Earth and Wikimapia, the Space Applications Centre (SAC) of ISRO has come up with 'Bhuvan', bringing India's name into the limelight yet again. Bhuvan, which literally means 'earth', is a web-based tool like Google Earth, but it promises better 3-D satellite imagery of India than what is currently being offered by other Virtual Globe software.
Bhuvan gives you an easy way to experience, explore and visualize IRS images over Indian region
Basic features of Bhuvan:
- Access, explore and visualise 2D and 3D image data along with rich thematic information on Soil, wasteland, water resources etc.
- Visualise multi-resolution, multi-sensor, multi-temporal image data
- Superpose administrative boundaries of choice on images as required
- Visualisation of AWS ( Automatic Weather Stations) data/information in a graphic view and use tabular weather data of user choice
- Fly to locations ( Flies from the current location directly to the selected location)
- Heads-Up Display ( HUD) naviation controls ( Tilt slider, north indicator, opacity, compass ring, zoom slider)
- Navigation using the 3D view Pop-up menu (Fly-in, Fly out, jump in, jump around, view point)
- 3D Fly through (3D view to fly to locations, objects in the terrain, and navigate freely using the mouse or keyboard)
- Drawing 2D objects (Text labels, polylines, polygons, rectangles, 2D arrows, circles, ellipse)
- Drawing 3D Objects (placing of expressive 3D models, 3D polygons, boxes)
- Snapshot creation (copies the 3D view to a floating window and allows to save to a external file)
- Measurement tools (Horizontal distance, aerial distance, vertical distance, measure area)
- Shadow Analysis (it sets the sun position based on the given time creating shadows and effects the lighting on the terrain)
- Urban Design Tools (to build roads, junctions and traffic lights in an urban setting)
- Contour map ( Displays a colorized terrain map and contour lines)
- Draw tools (Creates simples markers, free hand lines, urban designs)
Bhuvan's edge over Google Earth
| Google Earth | Bhuvan |
| Zoom levels up to 200 mt | Zoom levels up to 10 mt |
| Single layer information | Multi-layer information |
| Images upgraded every 4 years | Images upgraded every year |
| No alternate viewing options | Options of viewing on different dates |
| Uses international satellites | Uses Indian satellites |
