ABSTRACT

This research investigates the impacts of artificial lights intensity, emitted from built-up area, on population estimation utilizing SNPP VIIRS DNB and land use and land cover (LULC) data. To do so, the performance comparison of population prediction for individual metropolitan cities and provinces in South Korea was made with simple regression model (SRM) consisting of two kinds of nighttime lights (NTL) intensity derived from only built-up area and all types of LULC. The SRM of urban land use was found to be superior to that of all LULC types in terms of positive correlation, model fit, statistical significance, and population prediction results. Nonetheless, according to regression diagnotics, this model was hard to satisfy the basic assumption of linearity. Therefore, it was required to refine the current model with either the adoption of polynomial or the transformation of variables to predict population in future research.
