A dataset of spectral classes for global inland and coastal water bodies spanning 1984–2021

A global spectral class dataset for inland and coastal waters was established by leveraging all available high-quality Landsat 5 and 8 Collection 1 surface reflectance data from 1984 to 2021 with the aim of attaining a comprehensive understanding of the transformation in spatial and temporal scales across global inland and coastal waters over the past decades. Spectral class was obtained by utilizing the omni-spectral classification and scoring with near-infrared (OCN) method.
