An Empirical Line Model (ELM) was tested to correct Sentinel-2A (MSI) images acquired in the tropical archipelago of San Andrés, Colombia. This approach uses a linear regression to model the relationship between the average ground reflectance and radiance on bands 2, 3, 4, and 8, for 32 spectrally homogeneous targets. The model was validated from eight targets measured on different land-covers trough the estimated coefficient of determination R2 .
