Bhuvan, (lit: Earth), 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 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),〔http://www.medianama.com/2013/01/223-bhuvan-new-datasets/〕〔bhuvan.nrsc.gov.in/disaster〕 free satellite data and a products download facility,〔http://www.medianama.com/2014/02/223-bhuvan-upgraded-mapping-tool-2-5d-city-models-better-high-res-imagery-others/〕〔bhuvan.nrsc.gov.in/data〕 and rich thematic datasets.〔http://bhuvan.nrsc.gov.in/gis/thematic/index.php〕 Bhuvan is using a crowdsourcing approach to enrich its maps and collect point of interest data.〔http://trak.in/tags/business/2013/11/28/isro-bhuvan-android-app-bhuvanpoi-location-mapping/〕 It also acts as a platform for hosting government data (example - Karnataka Forest Department datasets).〔http://www.thehindu.com/news/national/karnataka/now-track-karnataka-forests-online/article3992540.ece〕〔http://bhuvan-noeda.nrsc.gov.in/projects/forest/kfd.php〕 A series of Bhuvan Application Services that are diversified and relevant for many ministries were released on August 12,2015 . These new application services include 1m Satellite images for more than 300 Cities in the country, Varieties of Applications for 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 crowd sourcing application for AP Housing Corporation Ltd., which has enabled geotagging of 3.8 million houses in AP with field photos and important attributes of housing in AP, Islands information system for developmental decision making for Border Management, MHA, Live link of the GIS databases of North East Region (NER) that showcases tools for better planning and development of NE States, A new tool on Bhuvan, enabling 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 & Archaeological Survey of India among others. One application on 3D city models/ views with Extrusions of the buildings and virtual city models was also released. This would be a useful tool for Smart City program of the Government. Other applications include Horticulture area mapping and assessment for Mango, Banana and Citrus fruits – A National Mission of DAC, MOA, Bhujal database and visualization – Country wide ground water maps, with state-wise access to the online services for drinking water and recharge structures, Geospatial tools for the 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 – Particular focus is on “Clean Ganga” Mission of MOWR. The tool “Bhuvan Ganga” now available on public domain for people to participate in providing vital information for Clean Ganga project. 〔http://pib.nic.in/newsite/PrintRelease.aspx?relid=124916〕 == Overview == () 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.〔http://www.gisresources.com/bhuvan-updates-gateway-indian-earth-observation/〕 At present 177 cities High resolution datasets are available,〔http://bhuvan3.nrsc.gov.in/applications/bhuvanstore.php〕 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-2D is developed using open-source software Geospatial solutions (UMN Mapserver, Geoserver, OpenLayers).2D images are available on all mobile browsers, including Apple's iOS.〔http://www.medianama.com/2013/08/223-bhuvan-goes-mobile-but-not-on-play-store/〕 All other Bhuvan applications and services are developed by taking Bhuvan-2D as a base. Bhuvan also provides faiclity to view satellite imagery in 3-Dimensional format. Earlier Bhuvan-3D was based on a product of Skyline Software Systems. On the 5th Anniversary of Bhuvan on 12 August 2014 Bhuvan has released an Open-source tool (Cesium : webGL Javascript Library) based Virtual Globe.〔http://bhuvan.nrsc.gov.in/globe〕 This 3D tool is platform independent and Plug-in free. Bhuvan also provides an android based application for field data collection.〔http://nrsc.gov.in/bhuvanpoi.html〕〔http://trak.in/tags/business/2013/11/28/isro-bhuvan-android-app-bhuvanpoi-location-mapping/〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bhuvan」の詳細全文を読む スポンサード リンク
