Abstract:
A research was conducted to mapping of sugarcane areain Cuddalore district of Tamil Nadu using Sentinel 1A C band VH polarized SAR satellite data during January 2018 December 2018. 29 temporal series data downloaded from https://scihub.copernicus.eu/dhus/, were pre-processed to derive dB and σ° values by using the customized Maps cape software. The dB value was found to be minimum of -17.7738 at planting to germination stage (4-5 weeks Feb and Mar) and maximum of -12.8387 at grand growth phase (5th month onwards Aug, Sep, Oct). Phonological variation of sugarcane crop and the multi temporal features were extracted from temporal dB of VH polarized images. Total Sugarcane area was assessed to be 11,849 ha. Accuracy of the map to validate with the ground controls had been done by the confusion matrix, which having the overall accuracy around 88.25% and the kappa co-efficient of 0.77.
