Bhuvan, (lit: Earth), is a web mapping service 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 and providing content in four local languages. A beta version was launched on 12 August 2009.
Apart from visualization, Bhuvan provides timely disaster support services (domestic and international), free satellite data and a products download facility, and rich thematic datasets. Bhuvan is using a crowdsourcing approach to enrich its maps and collect point of interest data. It also acts as a platform for hosting government data (example - Karnataka Forest Department datasets).
A diverse series of Bhuvan Application Services, relevant for many ministries of the Government of India, was released on August 12, 2015. This includes satellite images for more than 300 cities in the country, at a 1-metre resolution. Examples of the types of applications include the following: - Forest and Environment sector of MOEFCC – Depiction of ENVIS centre database “CRIS” to highlight various environmental parameters. - Toll information system for NHAI – A national database of national highways and Toll plazas - Geotagging and controlled crowdsourcing application for AP Housing Corporation Ltd., which has enabled geotagging of 3.8 million houses in Andhra Pradesh with field photos and important attributes. - Islands information system for developmental decision making for Border Management, Ministry of Home Affairs. - Live link of the GIS databases of North East Region (NER) that showcases tools for better planning and development of the Northeastern States, - A new search tool on Bhuvan enables data discovery and metadata display for the ease of navigation by the user community. - Cultural heritage sites of the country and its management on geospatial platform – National database for Ministry of Culture and the Archaeological Survey of India. - A viewing application that contains 3D city models, complete with extrusions of buildings and virtual city models. This is useful for visualizations of proposed Smart City infrastructure elements. - Agricultural area mapping area assessment for Mango, Banana and Citrus fruits. – A National Mission of DAC, MOA, Bhujal database and visualization. – Country-wide groundwater maps, with state-wise access to the online services for drinking water and artificial-recharge infrastructure. - Geospatial tools for schools – GIS for class 9 and class 10, including neighbourhood mapping tools for school children as part of School Bhuvan. - GAIL pipeline surveillance and monitoring system, pilot scale implementation for 640 km stretch in Gujarat. - E-governance model for image and geospatial based techniques. - Mobile smart phone applications for varieties of crowd sourcing applications – A particular focus is on the “Clean Ganga” Mission of Ministry of Water Resources. The tool “Bhuvan Ganga” now available in the public domain for people wishing to participate in contribute data to the Clean Ganga project.
[ISRO] launched the beta version of its web-based GIS tool, Bhuvan, on August 12, 2009. Bhuvan offers detailed imagery of Indian locations compared to other Virtual Globe Software, with spatial resolutions ranging up to 1 metre. At present 177 cities High resolution datasets are available, while the other part of the country is covered by 2.5m resolution imagery. Locations will be viewable from different perspectives, and the software will also provide functionality for the measurement of distances and other geoprocessing capabilities. The Bhuvan portal is designed to run on slow Internet connections. The images available do not include any military installations in India, due to security concerns.
The National Remote Sensing Agency played an important role in the development of this product. ISRO has used data provided by satellites including Resourcesat-1, Cartosat-1 and Cartosat-2 to get the best possible imagery of India.
Bhuvan allows users to view 2D and 3D images, along with information on soil, wasteland and water resources on the Indian subcontinent. Users can superimpose administrative boundaries of their choice, from a selection of boundaries available, on images as required. Bhuvan also allows visualization of AWS (Automatic Weather Station) data in the graphic view, as well as in tabular form. Users can "fly" from one location to another, and also navigate using the 3D view pop-up menu (with fly-in, fly out, jump in, jump around and view point controls). The software features Heads-Up Display (HUD) navigation controls (tilt slider, opacity control, compass ring and zoom slider). There is also a drawing function, which allows users to draw certain objects in both 2D (text labels, polylines, polygons, rectangles, 2D arrows, circles and ellipses) and 3D (placing of expressive 3D models, 3D polygons and boxes). Users can create snapshots (copies the 3D view to a floating window and allows to save to an external file) to record images and use measurement tools (horizontal distance, aerial distance, vertical distance, measure area) to record distances. Shadow analysis also allows a user to view terrain as it would appear at a specified time of day, by setting the sun position appropriately for the given time, thus creating accurate shadows and lighting.
ISRO plans to allow the end-user to participate in the development of features for the product in the future.
Some of the functionality planned for future versions includes:
- Online shapefile creation
- Urban Design Tools (to build roads, junctions and traffic lights in an urban setting)
- Contour maps (displays a colourized terrain, maps and contour lines)
- Terrain profile (displays the terrain elevation profile along a path)
- Draw tools (creates simple markers, free hand lines and urban designs)
- Navigation map (to jump to and view locations in 3D)
Bhuvan-3D released in 2009 requires Plugin and best viewed on IE 8 in windows machine. However, on its 5th anniversary(12 Aug 2014), Bhuvan has rolled our platform & plug-in independent Bhuvan 3D.
Bhuvan 2D is compatible with all browsers and operating systems and does not require any plug-in installation. Bhuvan 2D is based on the open source application Geo-spatial solutions. Bhuvan 2D can also be accessed through mobile phones also without any plugin installation.
The previous version of Bhuvan 3D can run only on the Windows operating system and is optimized for Internet Explorer 6 and higher, with Protected Mode turned off. Bhuvan uses a plugin which is around 11 MB in size, and has to be installed prior to access. The plugin is only supported on Internet Explorer for Microsoft Windows. Google Chrome, Firefox and other platforms were not supported.
Since the launch of Bhuvan, users have experienced various difficulties. One problem is that the Bhuvan site has, at various times, been either inaccessible or very slow (due to less band width and servers). Users are required to register before they can use the product, and downloads of plug-ins up to 11 MB in size are needed for the application to work. Furthermore, the plugin only works on Windows, and only Internet Explorer is supported. However now Bhuvan is improving and does not require Login to visualize the maps. Users need to register only when they wish to download satellite data (up to 25m resolution LISS-III data) and products (like NDVI, OHC datasets, Cartosat Digital Elevation Model etc.) To overcome the Plugin restrictions and platform-dependency for 3D -visualization, Bhuvan has come with a WebGL based open-source virtual globe. It only requires WebGL enabled browsers.
It renders layers unevenly and sometimes images are completely blocked. Bhuvan promises images from a perceived altitude of 10 metres, but technical analysts[who?] dispute the results. If many locations of same name exist, Bhuvan is supposed to give multiple results so that users can choose the intended location, but Bhuvan sometimes fails to return multiple results.
Since the initial, buggy beta release, a more stable version has been released, with which users have reported fewer problems. A discussion forum has also been started for users experiencing difficulties.
