摘要

The Indian Space Research Organisation (ISRO) began its space-based Earth Observation Programme in an experimental mode with Bhaskara-1 in 1979, from a low earth orbiting platform. Operational Earth observation activities from a geostationary platform began with the Indian National Satellite (INSAT) series (since 1982) with Very High Resolution Radiometer (VHRR) payload. The Indian Remote Sensing (IRS) satellite series, since 1988, has been providing Earth observation data in a wide range of spatial, spectral, radiometric and temporal resolutions using push-broom technology optical imaging sensors. The data from these optical sensors have contributed to various application activities encompassing resource monitoring, agricultural crop-yield forecasting, prospective fishing-zone identification, cyclone monitoring and tracking, weather monitoring and forecasting, cartography and disaster management, etc.
