Development of Techniques for Remote Sensing of Agriculture, Geosphere & Biosphere Programme
Field of Expertise:
Remote sensing and GIS applications of agriculture, agro-ecosystems and agro-environment. Contributions towards development of techniques, methodology, applications, project conceptualization, formulations and implementation. Remote sensing and GIS based crop area/production using optical and SAR data, Cropping systems and Agro-environment studies, hyperspectral remote sensing, Green house gases from agriculture.
Was involved in development of procedures and techniques of preharvest crop production estimations using satellite data, collateral data and meteorological data) for major crops like wheat, rice, grain sorghum, mustard and potato through digital image processing and crop yield models. Was a part of on SAR-Rice studies in India and national kharif rice acreage estimation project. Has worked on cropping systems analysis and demonstrated the utility of IRS LISS III and WiFS/AWiFS data to derive seasonal cropping pattern, crop calendar, crop rotation maps. The specific use of remote sensing based rice area derivation and stratification in GIS environment for large area sampling, coupled with field data and extrapolation towards generation of spatio-temporal methane emission maps and non-point source pollution. Has worked on hyperspectral remote sensing techniques of vegetation. Lead FASAL and CHAMAN projects at SAC.
