India today launched a geoportal which enables the user to easily access information on basic natural resources in the geospatial domain, particularly the Indian images and thematic information in multiple spatial resolutions. The “ Bhuvan” whose beta version was launched by Minister for Science and Technology and Earth Sciences, Shri Prithviraj Chavan in New Delhi at a function organized by Astronautical Society of India , showcases Indian images by the superimposition of the Indian Remote Sensing (IRS )satellite imageries on 3D globe. Several leading Scientists including Member Planning Commission, Dr. K Kasturirangan, Dr. G Madhavan Nair who is also the Chairman, ISRO/ Secretary, Department of Space, Secretary, DST, Dr. T. Ramasami, Secretary, Ministry of Earth Sciences, Dr Shailesh Nayak, former Chairman of ISRO, Prof. UR Rao, DG IMD, Dr. Ajit Tyagi witnessed the moment which opened the door to graphic visualization of digital geospatial India.
Bhuvan which can be accessed at http://bhuvan.nrsc.gov.in, 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 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.
Thus, Bhuvan represents, in essence, the whole India on your computer. It enables user to fly from space to street level, to grab, spin and zoom down to any place. One can also use Bhuvan to learn more about geography, and use Bhuvan layers to study natural resources, demographics, and transportation in specific contexts. It provides tools for measuring, drawing, saving, printing and most importantly, for visualizing thematic information.
