Satellite inventory of human settlements using nocturnal radiation emissions: The results show that the proposed methods effectively reduced the over-glow effect caused by DSMP-OLS data and achieved better results compared to the results from the traditional thresholding technique. Sutton , Christopher D. Earth and Environmental Science , Volume 17 , conference 1. Cloud-free coverages tally the total number of observations that went into each arc second grid cell.
