Crop Mapping using SAR Imagery: An Review
Main Article Content
Abstract
Agriculture is the backbone of Indian economy & is the pivotal sector for ensuring food security. Timely availability of information on
agricultural crops is vital for making well versed decisions on food security issues. It is very important for national government to know what
type of crops are being grown in which region in the current growing season, which will be useful in budget planning for import & export of
food products. Traditional ground survey method is laborious, time consuming & expensive. Along with this, continuous monitoring of crops is
highly difficult. Crop area estimation is a key element in crop production forecasting and estimation. The efficiency of crop area estimation
using satellite imagery depends on the accuracy of crop classification.
