Imagine if you could count the lions in Gir or fishermen find concentration of fish in the sea, just by dragging a mouse on a computer screen. Space Applications Centre of ISRO has just made that possible by an innovation called Bhuvan.

What Is ISRO BHUVAN???

ISRO’s Bhuvan (which means Earth) is a satellite mapping tool similar to Google Earth and Wikimapia. It was developed by Indian Space Research Organisation (ISRO). It offers resolution up to 10 metres and is considered as a rival to Google Earth and Wikimapia.

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.

This will provide better resolution compared to existing mapping solutions. Bhuvan will feature a zoom level of up to 10 meters while the Google Earth features a zoom level of up to 200 meters. ISRO has also decided to make a tracking and mapping antenna(30×15)m the largest in India in Chennai for advanced 3D mapping and resources.

BASIC FEATURE OF ISRO BHUVAN...

  1. Access, explore and visualise 2D and 3D image data along with rich thematic information on Soil, wasteland, water resources etc.
  2. Visualise multi-resolution, multi-sensor, multi-temporal image data
  3. Superpose administrative boundaries of choice on images as required
  4. Visualisation of AWS ( Automatic Weather Stations) data/information in a graphic view and use tabular weather data of user choice
  5. Fly to locations ( Flies from the current location directly to the selected location)
  6. Heads-Up Display ( HUD) naviation controls ( Tilt slider, north indicator, opacity, compass ring, zoom slider)
  7. Navigation using the 3D view Pop-up menu (Fly-in, Fly out, jump in, jump around, view point)
  8. 3D Fly through (3D view to fly to locations, objects in the terrain, and navigate freely using the mouse or keyboard)
  9. Drawing 2D objects (Text labels, polylines, polygons, rectangles, 2D arrows, circles, ellipse)
  10. Drawing 3D Objects (placing of expressive 3D models, 3D polygons, boxes)
  11. Snapshot creation (copies the 3D view to a floating window and allows to save to a external file)
  12. Measurement tools (Horizontal distance, aerial distance, vertical distance, measure area)
  13. Shadow Analysis (it sets the sun position based on the given time creating shadows and effects the lighting on the terrain)
  14. There would be many more value added functions and facilities which will be added into the package from time to time.
  15. Particular interest of ISRO/DOS would be to provide such functionalities to common man so that he/she adopts participatory approach with scientists to solve simple problems easily and interactively.
