Application of Remote Sensing
Remote Sensing
Remote Sensing is the acquisition of information about an object or any phenomenon without making any physical contact with that object. It is a phenomenon that has numerous applications including surveying, photography, geology, forestry and many more. But it is in the field of agriculture that remote sensing has found significant use. There are many applications of remote sensing on natural resources.
Agriculture & Soil
Contemporary techniques of satelite remote sensing uses to collect the information on crop statistics which is required for planning and decision making purposes, such as, distribution and storage of food grains, food security , Govt. policies, pricing and so on. Space data is used in addressing in many critical aspects, such as, crop are estimation, crop yield and production estimation, crop condition, basic soil information, cropping system studies, experimental crop insurance, etc.
Mahalanobis National Crop Forecast Center uses space based observations, at national level, for pre-harvest multiple crop production forecasts of nine field crops. Remote sensing based acreage and yield forecast based on weather parameters or spectral indices are used to provide production forecasts.

Land Resources
Management of our natural resources in one of the important aspect for sustaining a healthy economy and move forward with regard to developmental agenda. ISRO carries out Natural Resources mapping on a regular basis, aimed as systematic mapping and creation of GIS data base to help in development of country.
AWiFS data is continuously used through-out the year to prepare seasonal Land use/Land cover maps of the country. All seasonal images are finally aggregated at the end of the year to produce the national land cover map of India.
LISS-III data is used fro publicaton of land use maps of the country at 1:50,0 scale once in 5 years. Special initiative was taken to even prepare 1:10,000 scale land use maps of the nation using the synthesised data CARTOSAT and LISS-IV, which is effectively usable at Panchayat level planning and development.
Land Degradation Mapping
Land degradation mapping is taken up by ISRO with partner Institutions, under Natural Resources Cencus (NRC) mission of DOS/ISRO, towards generating information on land degradation at 1:50,000 scale using 23m resolution (multi-temporal & multi spectral) IRS data
Two cycles of land degradation mapping at 1:50,000 scale, for the timeframe 2005-06 and 2015-16, have been accomplished.
