- 20. Other services... • Weather services • Disaster specific datasets • Ocean services • Navigation maps • User added content
- 21. 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
- 22. • 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

- 5.8 meters of resolution with the least spatial resolution being 55 meters from AWiFS Sensor.
- Users can choose Bhuvan 2D or Bhuvan 3D for EO visualisation , Open EO data archive for downloading IRS satellite data and products, and thematic data dissemination for obtaining interoperable OGC web services Different supporting components like – interactive videos, virtual tour, discussion forum, help documents are also available.
- The two dimensional (2D) Bhuvan, a web mapping service application based on OpenLayers open source project, offers powerful, user-friendly mapping technology to organise the satellite data and map along with myriad information geographically with no server-side dependencies in an easy way. Bhuvan 2D is a slick, exciting online mapping application. It provides a highly responsive, intuitive mapping interface with detailed imagery and map data embedded. Some of its functional capabilities include map navigation, drawing point line, polygon, online shapefile creation, Geoprocessing overview map, linear and areal measurement. These capabilities combine to make Bhuvan 2D a compelling product
- Bhuvan 3D showcases images in a multi-sensor, multi-platform and a multitemporal domain. It lets you access, explore and visualise IRS image and a bundle of rich thematic information in 3D landscape. On Bhuvan 3D, 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. The urban design tools are a magic galore. Here you can virtually build roads, junctions and traffic lights in an urban setting! Experience all this just on Bhuvan 3D
- The Disaster Management Support (DMS) Program of ISRO, commits to providing timely support and services from aero-space systems, both imaging and communications, for strThese include creation of digital data base for facilitating hazard zonation, damage assessment, etc., monitoring of major natural disasters using satellite and aerial data, development of appropriate techniques and tools for decision support, establishing satellite based reliable communication network, deployment of emergency communication equipments and R&D towards early warning of disasters. The Decision Support Centre (DSC), set up at NRSC under the DMS program, is the single window of ISRO to provide the information for efficient disaster management. It operates on 16x7 basis during normal time and on 24x7 basis during disasters. Similarly, all information on disasters generated by DSC is ported onto Bhuvan for the use of the common man. Active forest fire incidents derived using MODIS Terra/ Aqua and DMSP-OLS data disseminated through NRSC's web site (INFFRAS) is also shown on Bhuvan on a daily basis.engthening the resolves of disaster management in the country.
- Potential Fishing Zones PFZ forecasts are operationally disseminated to all the maritime States including the two Union Territories since 1993. An integrated approach for Potential Fishing Zone based on Chlorophyll & SST have been developed, validated and transferred to Indian National Centre for Coastal and Ocean Information Services (INCOIS) for operational use. About 40,000 users are benefited through PFZ forecast. Data from Oceansat - 1 and Oceansat - 2 is being used for various applications within India. The most significant one being, the advisories of potential fishing zones and coastal water pollution, sedimentation monitoring, estimation of water vapour content in the atmosphere and the prediction of the onset of the monsoon. The data showcased on Bhuvan about the PFZ contains information about distance, direction, and the depth of the potential fishing zones
