Introduction

• Bhuvan is a software application which allows users to explore a 2D/3D representation of the surface of the Earth.

• The browser is specifically tailored to view India, offering the highest resolution in this region provided with local four languages.

• A beta version was launched on 12 August 2009.

• Bhuvan not only provide visualisation but also provide  timely Disaster support services (Domestic and international),Free satellite data and products download facility, Rich Thematic datasets.

Working with Bhuvan

• Bhuvan is a free web based visualisation system.Users can access Bhuvan by visiting www.bhuvan.nrsc.gov.in

• Bhuvan contains four segments:VisualizationServicesApplication SectorsSpecial Applications

• Interactive videos, virtual tour, discussion forum, help documents are also available.

Segments

Bhuvan2D

• Web mapping service application based on OpenLayers open source project.

• Highly responsive, intuitive mapping interface with detailed imagery and map data embedded.

• Its functional capabilities include:Map navigationDrawing point line, polygon, Online shapefile creation,Geoprocessing overview map, Linear and Areal measurement.

• Map Navigation

Map navigation is performed using scroll ,zoom in and zoom out tools.

• Drawing Point ,Line and Polygon

Draw Tool from tool menu is used to create point ,line and polygon features

• Linear measurement

To measure the length select Measure Length option from Tools menu

• Areal measurement

To measure area select Measure area option from Tools menu

Bhuvan 3D

• Shows images in a multi-sensor, multi-platform and a

multitemporal domain.

• Lets you access, explore and visualise IRS images and a bundle

of rich thematic information in 3D landscape.

• Users can fly to different locations on the terrain and experience

unparalleled 3D navigation.

• Bhuvan 3D has many unique features and easy to use intuitive

interface, where users can virtually experience the physical

characteristics of the terrain, especially the Indian landscape.

NRSC Open EO Data Archive

• NRSC Open EO Data Archive facilitates the users to select, browse and download satellite data and products.

• Through NOEDA Bhuvan has laid a step forward in serving Scientific and Research community by providing free data download.

• At present Cartosat-1:DEM: 1 arc sec, Resourcesat-1:AWiFS Ortho (2008,2009):56m, Resourcesat-1:LISS-III Ortho (2008-09):24m , IMS -1 : Hyper spectral Imager datasets ,Oceansat -2 (OCM) ,Oceansat-2 (Scatterometer) for Indian region are available

• It gives the option to select area based on 'Bounding Box, Mapsheet (SOI), Tiles, Interactive Drawing. Users can see thumbnail view, metadata and download the selected tiles

Conclusion

• Bhuvan is an interactive versatile visualization system

• In Bhuvan users can add their own points of interest and share them with others

• Users can delineate vector features as shape files

• Bhuvan can be connected to Global Positioning System(GPS) device in real-time or playback mode

• Users can chart routes, plot areas, view terrain profile and overlay images

• Useful for educators to teach subjects ranging from sciences to history. Also, take students virtually to an area being studied and show them the topography, surrounding areas etc.

• Useful for scientists to facilitate new possibilities from the IRS geospatial data for collaborative research

• Useful for administrators to monitor various developmental schemes at the grassroots level
