Generating Banana area map using VV and VH Polarized Radar Satellite Image
Abstract
An investigation was carried out to generate banana area map in major \nbanana growing districts of Tamil Nadu using polarized (VV and VH) Synthetic \nAperture Radar Satellite images Sentinel 1A SAR Data with VV and VH \npolarization at 12days interval were downloaded for the crop growing season. \nCrop parameter for classification was retrieved by continuous monitoring \nacross the study area Ground truth collection and accuracy assessment \nwas carried out using the validation points. Using temporal data collected \nfor the cropping period, spectral dB curve was generated for VV and VH \npolarization. The dB values do not show much variation both under VV and VH \npolarization. The total banana cultivated area as estimated for Tiruchirappali, \nKarur and Erode districts were 5457 hectares, 3865 hectares, and 9432 \nhectares respectively.
