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), 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).
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
