How does itwork?

Bhuvan is an interactive versatile visualization system that allows usersto navigate (or fly) the entire globe, scanning satellite imagery withoverlays of natural resource information, roads, geographic features,and numerous other location-specific data points. Users can add theirown points of interest and share them with others, chart routes, plot

areas, calculate distances, and overlay separate images onto theapplication. Bhuvan connects to the Internet, making online resourcesavailable inconnectionwithparticularplaces.

Users can show or hide available layers in any combination. Using thescale and the robust measurement and terrain analysis tools, this usercould plot mileages, calculate elevation difference and slope anglebetweentwo ormorepoints inthe 3DView,terrainelevationprofilealonga path, find places of interest along the way, and link to Web sites tocontact thoseestablishments.

Bhuvan has become a favorite for people needing to easily showlocations, such as a mining company giving a presentation aboutcurrent orpotential sites. Manyeducators useBhuvan to help studentsunderstand subjects ranging from sciences to History. Geologists cantake studentsvirtuallyto an area being studied and show them thetopography and surrounding areas, quickly zooming out and flying toother locations. Other scientists overlay images of different thematicinformation, such as land use, relating the land use to imagesof therealworld. Someadministrators have also found the applicationvaluable for

monitoringvariousdevelopmentalschemesatgrassrootslevel.

It is a free web based visualization system. By just logging on towww.bhuvan.nrsc.gov.inanddownloading and installing theplug-in (forfirst time use), users canaccessBhuvan and can fly to locations aroundthe world by either entering the names of places or the latitude and thelongitude coordinates. Zooming in and out determines the numberandkind of features or locations displayed astheresolutionchanges. Asyouzoom closer to a built-up area, for instance, smaller details and theirnamesbegin to appear. Onrendering, the thematic maps and its details

are clickable, opening a pop-up window with information about itsfeature, links to related resources, photos, or other information. Userscanchangethe orientation of thecompasspointsof themap and adjustthe aspect, such that the map is shown at any anglefrom directlyaboveto horizontal. Forareas rendered in3D,adjustingtheaspect gives

Know Bhuvan

the impression of moving through a real space. Users can add'Placemarks', which areclickable indicators of particular locations, andcreate 2D and 3D features, share, collaborate and chat, use powerfulurbandesign tools that integratesinto Bhuvan.

WithBhuvan,scientists, academicians, policymakers,or generalpubliccan leverage this integration of vast amounts of geospatial data in aneasy-to-use interfacewithoutanyadditional resources. Thetool's visualimmediacycould proveenormously beneficial, for example, for a surveyof variousgeologicalstructures inaregion. Individually, students canuseBhuvan to know and examine places they are studying. As it isinteractive, the application encouragesusers to keep coming back to itand exploreplacesof interest, scenes of events in thenews, or parts ofthecountrytheymaynevervisit inperson.

More than just a map, Bhuvan lets users create and share personalresources. Browsing and exploring distant locales augmented withcontributions from other users presents a compelling opportunity fordiscovery and learning. Contributing anecdotes, stories, and historieswill allowusers to communicateinacontextofgeography.

Bhuvan has become more sophisticated, with additional tools andincreased coverage of high-resolution imagery. The number of placesthat offer 3D imagery has also expanded. The dramatic views andcapabilities of the program have spawned communities of users who

develop content'Placemark' collections on particular topics, 3Dstructuresthat is available to others. Acting as a technicalinfrastructure, Bhuvan allows users to share personal histories andenabling virtual collaboration. Geographic notations can be found onmany topics for many different places, and by integrating with otherexisting applications, Bhuvan is positioned to become a spatiallybasedcollectionofprofound informationcoupled withfactsandknowledge.Blogs, user groups, social networking sites and forums are enabledwhere, they share ideas and experiences, using Bhuvan in variousscenarios, as well as post case studies they have created that use theapplication. As tools emerge to export content from Bhuvan to other

applications, such as video files, users will be able to create projectsusingBhuvanand sharethoseprojectswithothers.

ISRO is well known amongst space faring nations for itsworld-leading reputation in developing new, indigenousand innovative service oriented applications using remotesensing technology. Over the past 2 decades, ISRO has

mastered the art of developing these unique applicationsusing various spectral, spatial and temporal resolutionsoffered by the versatile IRS satellites and these have beensuccessfully institutionalized in many important areas ofpolicy making, natural resources management, disastersupport, and enhancing the quality of life across allsectionsof thesociety.

Bhuvan, an initiative to showcase this distinctiveness of

Indian imaging capabilitiesincluding the thematic information derived from suchimagery is of vital importance to common man. Bhuvan,an ambitious project of ISRO to take Indian images andthematic information in multiple spatial resolutions topeople with a web portal through easy access toinformation on basic natural resources in the geospatialdomain. Bhuvan showcases Indian images by thesuperimposition of the IRSsatellite imagerieson 3Dglobe.

It displays satellite images of varying resolution of India'ssurface, allowing users to visuallysee things likecities andimportant places of interest looking perpendicularly downor at an oblique angle, with different perspectives and cannavigate through 3Dviewingenvironment.

with a focus on Indian region

Thedegree of resolution showcased isbasedon thepointsof interest and popularity, but most of the Indian terrain iscovered upto at least 6 meters of resolution with the leastspatial resolution being 55 meters from AWifs Sensor. With

such rich content, Bhuvan opens the door to net centricvisualisation of digital geospatial India allowing individualsto experience the fully interactive terrain viewingcapabilities.

Multi-resolution images from multi-sensor IRS satellites ofIndia is seamlessly depicted through the Bhuvan webportalto enable commonman to zoom into specific areaofinterest at high resolution as per the prevailing Remote

Sensing Data Policy (RSDP) of the government. Bhuvanbringsa whole lot of uniqueness inunderstanding our ownnatural resources whilst presenting beautiful images andthematic information generated fromvarietiesof geospatialdata. Bhuvan also attempts to bring out the importance ofmulti-temporal data and to highlight the changes takingplace to ournatural resources, which will serve asa generalawareness on our changing planet. There are lot morevalue added services which will be enabled onto this Indian

EOvisualisationsysteminduecourseof timeand each oneof those services are going to be unique to preserving andconserving our precious natural resources through publicparticipation.
