Detection of oil pollution have been evaluated and assessed by several authors adopting such techniques as field spectroscopy, vegetation health indices, canopy water use efficiency and UAVSAR Polarimetric Backscatter and Decomposition among several others. However, no published study at the moment have sought to utilize and assess the potential of Spaceborne Sentinel1 C-Band SAR Datasets in the characterization of vegetation affected by oil pollution. In this study, field work was conducted across 3 sites of a recent, old and a non-polluted site. The field plot center point was used to retrieve image information for the various sites. Effort was made to assess the underlying characteristics of Sentinel -1 C Band derived Entropy and Alpha Plane Polarimetric scatterers and the field spectral responses. Result shows that the Alpha component of the dual polarization decomposition had stable scattering characteristics after the spill compared to the observed random scattering characteristics before the spill. This however indicates a feasible potential of the Alpha plane component scatterers for discerning stressed vegetation as a result of oil pollution. |
