Bhuvan (Indian Earth Observation Visualization) - ISRO's landmark achievement

Have you used Google Earth and had great feeling about it? Try using Bhuvan - you will get spectacular views & you will feel you are on top of the world. Bhuvan is another landmark achievement of Indian Space Research Organization(ISRO). It is a best Independence day gift from them. Bhuvan, an ambitious project of ISRO to take Indian images and thematic information in multiple spatial resolutions to people through a web portal through easy access to information on basic natural resources in the geo-spatial domain. Bhuvan showcases Indian images by the superimposition  of these IRS satellite imageries on 3D globe. It displays satellite images of varying resolution of India’s surface, allowing users to visually see things like cities and important places of interest looking perpendicularly down or at an oblique angle, with different perspectives and can navigate through 3D viewing environment. The degree of resolution showcased is based on the points of interest and popularity, but most of the Indian terrain is covered upto at least 5.8 meters of resolution with the least spatial resolution being 55 meters from AWifs Sensor. With such rich content, Bhuvan opens the door to graphic visualization of digital geo-spatial India allowing individuals to experience the fully interactive terrain viewing capabilities.

Bhuvan Features
* Visualise 2D and 3D image data along with rich thematic information on Soil, wasteland, water resources etc.
* 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)

Here is the view of India's Green City - Bangalore.

Go ahead and register to enjoy spectacular view of the world from our own satellite. Here is the link - http://bhuvan2.nrsc.gov.in/Bhuvan/WebClient/PresentationLayer/WebClient/usr_reg.asp

Bhuvan Plugin Client Setup link - http://bhuvan2.nrsc.gov.in/Bhuvan/WebClient/PresentationLayer/WebClient/BhuvanSetup.exe

P.S.: To my knowledge, I find the plugin works only with IE not with firefox. If your bandwidth is not much you will not feel the smooth navigation across places. Please be patience and let us give sometime for the software to mature.
