Bhuvan is an initiative to showcase this distinctiveness of Indian imaging capabilities including the thematic information derived from such imagery which could be of vital importance to common man with a focus on Indian region.  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 geospatial 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 visualisation of digital geospatial India allowing individuals to experience the fully interactive terrain viewing capabilities.

Multi-resolution images from multi-sensor IRS satellites of India is seamlessly depicted through the Bhuvan web portal by enabling a common man to zoom into specific area of interest at high resolution. Bhuvan brings a whole lot of uniqueness in understanding our own natural resources whilst presenting beautiful images and thematic vectors generated from varieties of geospatial information. Bhuvan will also attempt to bring out the importance of multi-temporal data and to highlight the changes taking place to our natural resources, which will serve as a general awareness on our changing planet.  There are lot more special value added services which will be enabled onto the web portal in due course of time and each one of those services are going to be unique to preserving and conserving our precious natural resources through public participation.  We are sure the common man will get rich benefits from these Indian geospatial data services in days to come.

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) navigation 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)

•There would be many more value added functions and facilities which will be added into the package from time to time.

•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.

◦Navigation map (to jump to and view locations in the 3D India)

Bhuvan  FAQ

What is Bhuvan?

Bhuvan is a geoportal that provides medium to high resolution satellite imagery of virtually the entire India over the internet. You can "fly" around using mouse and keyboard on a simple desktop computer with virtual globe in front draped with IRS images over Indian region. Many other features are built in, including 3D terrain and information on many thematic data.

What can Bhuvan do for me?

Bhuvan is a free web based image portal. Most Image visualization programs are very expensive and complex. Bhuvan provides a fast and friendly way to look at IRS satellite data and thematic information in geographic context, which is invaluable for management, planning and visualization. Additionally, Bhuvan makes it easy to share digital data between people and computers anytime, anywhere.  Over a period of time a lot more unique functionalities will be added into this tool to address common man's problems, particularly in the rural setup of India and addressing natural resources management issues.

What do I require to run Bhuvan on my Machine?

You require the Bhuvan Plug-in which can be downloaded from the Bhuvan website after registration and you will also need DirectX9 or higher version (www.microsoft.com/windows/directx/) for installing the plug-in. Please note that the Bhuvan Plug-in can be installed with administrative privileges only.

How do I use Bhuvan?

When you first open Bhuvan website, You will land on the index page which gives you information on Bhuvan and this page also allows you to register for using the Bhuvan. Once you successfully register, you will land on the Bhuvan 3D client page. Here, there are three primary areas of the program that you'll be using. The main window shows a globe, and you can navigate around with your mouse or use the Heads-Up Display (HUD) option available on the right top corner. Double right click to zoom in, and double left click to zoom out (or use your mousewheel). Right click, hold, and drag to pan. The second area is at the upper right of the main window. When you move your mouse over the navigation compass, it give you more movement options such as rotate and tilt (which you can also do with your mouse). The third area is to the left of the main window. This frame includes a fly to location and fly to important places option. On the top of the globe are the menu options for layers, 2D and 3D drawing, measurement tools, snapshot tools etc. When you select any of these options, you see the context options on the left plane where you can make appropriate choices that you can turn on to make visible in the main windows such as roads, 3D terrain, and more.

 Can I use Bhuvan if I don't have a fast internet connection?

Yes. Bhuvan is designed to be as bandwidth-friendly as possible. However, it is dependent on continuously downloading a large amount of imagery. Consequently, the faster your connection, the better the program will perform. If you have a slow connection, Bhuvan will download imagery correspondingly slowly, but it will (eventually) download everything at the maximum available resolution.  Depending on the number of concurrent users on over servers and the kind of bandwidth at client end the ultimate speed of visualisation will be decided.  This is a beta release, however with more learnings we will be able to make things more comfortable for all types of users.
