Abstract

A random forest regression model was developed to estimate subpixel urban percentage using the Visible Infrared Imaging Radiometer Suite (VIIRS) data and high quality calibration information derived from the National Land Cover Database (NLCD) 2011. Accuracy assessment resulted in a mean absolute error of 3.57% and a root mean square error of 8.50%. A wall-to-wall map of urban land use across the conterminous U. S. (CONUS) in 2012 was produced, demonstrating the utility of VIIRS observations for urban mapping at regional to larger scales.
