Outline


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.
