Presently multi-sensors’ data of Indian region are available from numerous satellites. Efforts have been made to analyse optical and microwave remote sensing data at different optical bands and at microwave frequencies. The results show that these data are highly sensitive to the changes on the Earth surface, such as vegetation cover, snow cover, surface topography, forest cover, moisture content, water quality, and the water vapour in the atmosphere. The paper presents the analysis of data from multi-sensors for various wavelengths and frequencies from the Indian region and its surroundings. The application of these data in the early warning of various types of natural hazards in India such as drought, water pollution, snow avalanches, floods, earthquakes, forest fire, erosion and atmospheric pollution will be demonstrated.
