  3. Introduction of RS & GIS • RS Applications in Agriculture – a Unit in SS&AC Dept. started in 1989 • Soil Scientists trained in National and International Institutions • Used visual products for mapping Soil Resources • Delineated gypsum mined areas, water logged areas • Modeled soil erosion by water • Carried out varietal discrimination, biomass and yield estimation in field crops • Generated DTM of micro-watershed

  4. Introduction of RS & GIS • Department of RS & GIS from April 2010 • Multi-disciplinary team of scientists • Offers RS & GIS Courses for UG & PG Programmes • Generates Soil Resource Database • RI-SAT Data Application in Soil Moisture Monitoring • HRD-Training on RS & GIS Applications in Agri. • Research on Drought Monitoring using MODIS data • Hyperspectral Studies • Started PG Program in M.Tech.(Ag.) in Geo-informatics in 2013

  5. Agro-meteorological Advisory • Agro-Climatic Research Centre makes Medium Range Weather Forecasts • Offers Farm Advisory on Agricultural Operations • Conducts Climate Change related studies on Crop Growth using Crop Growth Models and Open Top Growth Chambers • Established AWSs in all Block and collects hourly data on weather parameters and use in downsizing weather forecasts

  6. Agri-tech Portal • An Agritech portal with five lakh and more pages is built and maintained by eExtension Unit • Received ‘Best e-Governance Award’ for the year 2011-12 • The portal provides technologies for crop production, animal husbandry • Hosts success stories of farmers and farmers’ innovations • Information on Government schemes, credit facilities and special technologies for entrepreneurs • The portal is updated on daily basis and visited by thousands of farmers, technologists, administrators and extension personnel every day • The e-Extension Centre has multiple video conferencing facility and connects to all the TNAU College campuses, Agricultural Development Centres

  7. Market Intelligence • Domestic and Export Market Intelligence Cell offers advisory services on marketing • Registered farmers receive prevailing prices in different local and export markets for the produces/products of their interest • Forecasts price for agricultural produce and value added products • Collects Cost of Cultivation of Principle Crops • Maintains a database on price of agricultural commodities from the leading markets of Tamil Nadu and neighbouring States

  8. RS & GIS Applications in Agriculture SOIL RESOURCE INVENTORY • Visual interpretation of FCC from TM & LISS and PAN sharpened LISS3 data • Digital classification of LISS3 data and integration of Physiography, Results of Terrain Analysis of DEM • Selection of sample strips and profile examination and laboratory analysis • Digital Soil Database for Tamil Nadu in NRIS of ISRO • Land Evaluation and Management Options and Crop Selection
