Bhuvan is a Geoportal of ISRO, to evince the Indian Earth Observation capabilities from the Indian Remote Sensing (IRS) series of satellites.
basically, the Bhuvan word means Earth in the Sanskrit language. It is an interactive versatile Earth-Browser which showcases multi-sensor, multi-platform and multitemporal images with capabilities to overlay thematic information, interpreted from such imagery as a vector layer, along with near real-time information from Automatic Weather Stations (AWS), Potential Fishing Zone (PFZ) information, disaster support related information like forest fire alerts, periodic agricultural drought assessment, etc.
ISRO is well known amongst space-faring nations for its world-leading reputation in developing new, indigenous and innovative service-oriented applications using remote sensing technology. Over the past 2 decades, ISRO has mastered the art of developing these unique applications using various spectral, spatial and temporal resolutions offered by the versatile IRS satellites and these have been successfully institutionalized in many important areas of policymaking, natural resources management, disaster support, and enhancing the quality of life across all
sections of the society.
Bhuvan an initiative to showcase this distinctiveness of Indian imaging capabilities including the thematic information derived from such imagery is of vital importance to the common man. Bhuvan an ambitious project of ISRO to take Indian images and thematic information in multiple spatial resolutions to people with a web portal through easy access to information on basic natural resources in the geospatial domain. Bhuvan showcases Indian images by the superimposition of the IRS satellite imageries on 2D/ 3D virtual 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 a 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 up to at least 6 meters of resolution with the least spatial resolution being 55 meters from AWiFS Sensor, while some cities are having 2.5 meters and 1-meter
resolution. With such rich content, Bhuvan opens the door to the net-centric visualization of digital geospatial India allowing individuals to experience the fully interactive terrain viewing capabilities.
It can do lots of things-
*Ranging from visualization, Bhuvanites can also download, IRS data products and consume thematic datasets as, OGC web services towards Geoprocessing.
*A Place where users can add their own points of interest, and share them with others, Can delineate vector features as shapefiles
*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
Bhuvan Features
