Rice Mapping and Various Stages of Rice Growth using Sentinel-1 SAR Data-A case study of Mahabubnagar District, Telangana

Space Based technology both optical and microwave SAR Data is used to monitor the Earth at regular intervals which has its application in various fields viz., agriculture, water, urban so on. Synthetic Aperture Radar (SAR) advantage penetrate through clouds, day-night imaging, all weather conditions high resolution making it an effective system for crop monitoring, especially during Monsoon Season, as Optical Sensors doesn’t provide cloud free data. Sentinel-1 data been recent studies map rice-growing areas. The IW GRD were ricegrowing area over Mahabubnagar District of Telangana State, was processed SNAP Software. Few plots selected by conducting field survey Kharif 2021. Vegetation Index (RVI) have fluctuations stages rice growth. This paper explains how multi temporal observations can be growing stages, well interpret σ°VHand σ° VV back scattering co-efficient.
