bhuvan liss3 dataset

Bhuvan is manoeuvre to display the diversity of Indian imaging capabilities including the thematic information derived from imagery is of vital importance to common man. Bhuvan an ambitious project of ISRO to take Indian images and thematic information in multiple spatial resolutions to people with a web portal through easy access to information on basic natural resources in the geospatial domain. Bhuvan showcases Indian images by the superimposition of the IRS satellite imageries on 2D/ 3D virtual globe.

This geoportal owned by the government of India, operated on Indian remote sensing (IRS) series of satellites. Along this data sets from satellites, it also coney and iterate real-time data sets from Automatic Weather Stations (AWS), Potential Fishing Zone (PFZ) information, disaster support related information like forest fire alerts, periodic agricultural drought assessment etc. This web-application which combines information from various sensors, platforms and multi temporal images to compute thematic information, interpreted from such imagery as a vector layer. Bhuvan enables net-centric visualisation of digital geospatial India allowing individuals to experience the fully interactive terrain viewing capabilities. Apart from visualisation, Bhuvan facilitates user to browse, select and download satellite data and products through NOEDA. Through Thematic Services it also facilitates to select, browse and query thematic datasets and consume as OGC web services. Bhuvan brings a whole lot of uniqueness in understanding our own natural resources whilst presenting beautiful images and thematic information generated from varieties of geospatial data.

Enlisting the feature of Bhuvan geoportal, it provides the general public, students, scientists, policy makers leverage to use, download and analyse the wide (two or three dimensional) range integrated data in multi-linguals graphic user interface without any additional resources. This encourages the students to download specified satellite data and explore new data sets along with creation and sharing personal resources like data sharing.

Bhuvan has various options to be chosen by the user like two dimensional or three dimensional EO visualisation, free download option named open data archive and EO derived product called climate and environment. The maps and OCG services like thematic services, disaster management support system, ocean services and create a map or GIS. Portal is equipped with modules from central government dashboard called as Governance/ central ministries (g-governance dashboard) which encloses sub modules like Hailstorm, chaman: Coordinated Programme on Horticulture Assessment and Management using Geoinformatics, horticulture, pest surveillance, plantation, Pradhan Mantri Krishi Sinchayee Yojana (PMKSY), Rashtriya Krishi Vikas Yojana, Portal for geotagging of location where Yoga activities is been performed, Institutionalized Geo-tagging for inventory and best practices in governance (Andhra Pradesh),  Monitoring of polling station during election in AP, Disaster Management Portal for HUDHUD Cyclone, NTR Vaidya Seva Trust, Initiated a g-Governance service portal for decision making (Andhra Pradesh Arunachal Pradesh and Assam), Tourism GIS (Vijayawada). Application sector enclosed seven main categories and twenty-five sub-categories. Main categories consist of forestry, agriculture, E-governance, water, tourism, urban and rural. Last module is of special application equipped with data discovery, decision support dashboard, histological products, image gallery, international disasters, multilingual translation, online shapefile creation, OSCAT- 3D, smart tracking and suvidha.

By integrating with other existing applications, Bhuvan is poised to become a spatially based collection of profound information, coupled with facts and knowledge. Blogs, user groups, social networking sites and forums are enabled for users to share ideas and experiences, and post case studies also.
