With large coast line, India is susceptible for cyclones. It is important to understand the impacts of cyclone, with respect to its earlier footprints, low lying areas, etc, wherein satellite images provide such inputs. Using historical satellite data and Digital surface models, these inputs are derived.
ISRO uses geo-stationary and low earth orbit satellites for providing experimental inputs on cyclogenesis, cyclone track, cyclone intensity. INSAT series of satellites with frequent imaging provide the cyclone parameters for near real time analysis.
Near real time information on inundation due to cyclones is derived, using optical and microwave SAR data and the information is provided to the concerned departments. During 2018, ISRO provided information on inundation to Odisha, Andhra Pradesh States during TITLI, PHETHAI, etc.
