Bhuvan is the geoportal of the Indian Space Research Organisation, run by the National Remote Sensing Centre. It provides access to Indian Earth observation imagery, a national base map, thematic datasets (land use, hydrology, disaster, agriculture), and elevation models.
Many products are free to download after registration, with some served through WMS for direct mapping. Bhuvan is the authoritative source for satellite-derived data over India, complementing the tabular focus of Data.gov.in.
