|Remote Sensing and Geographic Information System (GIS) technologies are widely used in various fields of agriculture viz., Soil
Resource Management, Watershed Management, Land Degradation Assessment, Command
Area Development, Monitoring and Assessment of Soil Moisture, Monitoring of in-season Agricultural Operations, Crop Inventory, Crop Health Monitoring, Crop
Damage Assessment etc. Remote Sensing and GIS is used as a decision making tool
for optimization of resource utilization, distribution of agricultural inputs
and marketing activities.
Realizing the utility of Remote Sensing and GIS techniques, Tamil Nadu Agricultural University implemented a scheme on, ‘Remote Sensing for Agricultural Applications’ in 1990. It was functioning as a unit in the Department of Soil Science and Agricultural Chemistry and was established as a separate department in 2010 by involving the scientists of various disciplines for wider application of remote sensing and GIS techniques in the areas related to agriculture.
