Bhuvan ( Fly around the world ) software by ISRO

Welcome To Bhuvan ( fly to locations around the world by either entering the names of places or the latitude and the longitude coordinates.)

A Geoportal of Indian Space Research Organisation Showcasing Indian Imaging Capabilities in Multi-sensor, Multi-platform and Multi-temporal domain. This Earth browser gives a gateway to explore and discover virtual earth in 3D space with specific emphasis on Indian Region.
  • Bhuvan evinces Indian Imaging capabilities
  • Portrays Rich Thematic Information towards Societal applications
  • Experience OGC web services enabling interoperability
  • Robust API for ease of development and integration
  • Interactive 3D modeling and guided tours

What is it?
Bhuvan is an interactive versatile visualization system that allows users to navigate (or “fly”) the entire globe, scanning satellite imagery with overlays of natural resource information, roads, geographic features, and numerous other location-specific data points. Users can add their own points of interest and share them with others, chart routes, plot areas, calculate distances, and overlay separate images onto the application. Bhuvan connects to the Internet, making online resources available in connection with particular places.

Users can show or hide available layers in any combination. Using the scale and the robust measurement and terrain analysis tools, users can plot mileages, calculate elevation difference and slope angle between two or more points in the 3D view, terrain elevation profile along a path, find places of interest along the way, and link to Web sites to contact those establishments.

What can it do?
Bhuvan has become a favorite for people needing to easily show locations, such as a mining company giving a presentation about current or potential sites. Many educators use Bhuvan to help students understand subjects ranging from sciences to history. Geologists can take students—virtually—to an area being studied and show them the topography and surrounding areas, quickly zooming out and flying to other locations. Other scientists overlay images of different thematic information, such as land use, relating the land use to images of the real world. Some administrators have also found the application valuable for monitoring various developmental schemes at grassroots level.

How does it work?
It is a free web based visualization system. By just logging on to and downloading and installing the plug-in (for first time use), users can access Bhuvan and can fly to locations around the world by either entering the names of places or the latitude and the longitude coordinates. Zooming in and out determines the number and kind of features or locations displayed as the resolution changes. As you zoom closer to a built-up area, for instance, smaller details and their names begin to appear. On rendering, the thematic maps and its details are clickable, opening a pop-up window with information about its feature, links to related resources, photos, or other information. Users can change the orientation of the compass points of the map and adjust the aspect, such that the map is shown at any angle—from directly above to horizontal. For areas rendered in 3D, adjusting the aspect gives the impression of moving through a real space. Users can add ‘Placemarks’, which are clickable indicators of particular locations, and create 2D and 3D features, share, collaborate and chat, use powerful urban design tools that integrates into Bhuvan.

Why is it significant?
With Bhuvan, scientists, academicians, policy makers, or general public can leverage this integration of vast amounts of geospatial data in an easy-to-use interface without any additional resources. The tool’s visual immediacy could prove enormously beneficial, for example, for a survey of various geological structures in a region. Individually, students can use Bhuvan to know and examine places they are studying. As it is interactive, the application encourages users to keep coming back to it and explore places of interest, scenes of events in the news, or parts of the country they may never visit in person.

Bhuvan lets users create and share personal resources. Browsing and exploring distant locales augmented with contributions from other users presents a compelling opportunity for discovery and learning. Contributing anecdotes, stories, and histories will allow users to communicate in a context of geography.

Where is it going?
Bhuvan has become more sophisticated, with additional tools and increased coverage of high-resolution imagery. The number of places that offer 3D imagery has also expanded. The dramatic views and capabilities of the program have spawned communities of users who develop content—‘Placemark’ collections on particular topics, 3D structures—that is available to others. Acting as a technical infrastructure, Bhuvan allows users to share personal histories and enabling virtual collaboration. Geographic notations can be found on many topics for many different places, and by integrating with other existing applications, Bhuvan is positioned to become a spatially based collection of profound information coupled with facts and knowledge.

Blogs, user groups, social networking sites and forums are enabled where, they share ideas and experiences, using Bhuvan in various scenarios, as well as post case studies they have created that use the application. As tools emerge to export content from Bhuvan to other applications, such as video files, users will be able to create projects using Bhuvan and share those projects with others.
