Assessment of Spectral Signature of Lagos Coastline Region

Abstract

The increasing dynamics associated with coastal habitations have necessitated the need for an understanding of the changes that are taking place in this important natural environment. (Turner et al 1996). In recent times there has been an increase in the intensity, rate and rapidity of occurrence of dynamics associated with coastal environments (Passeri et al 2015). In this study, Satellite imageries covering 3 epochs (1986, 2000 and 2016) were utilized. Spectral signatures of Coastline areas in different periods were extracted through the classified features within the ArcGIS software to determine the minimum, maximum, mean and standard deviation of each band and reflectivity of each feature. The study shows spectral signature dynamics of Lagos coastline region are assessed. Also, change dynamics was carried out to see the obvious changes that had happened along the coastal region of Lagos.
