The Rnightlights package extracts raster and zonal statistics
from satellite nightlight rasters downloaded from the United States
National Oceanic and Atmospheric Administration (<http://www.noaa.gov>)
free data repositories. Both the DMSP-OLS annual and SNPP-VIIRS monthly
nightlight raster data are supported. Satellite nightlight raster tiles are
downloaded and cropped to the country boundaries using shapefiles from the GADM
database of Global Administrative Areas (<http://gadm.org>). Zonal statistics
are then calculated at the lowest administrative boundary for the selected
country and cached locally for future retrieval. Finally, a simple data
explorer/browser is included that allows one to visualize the cached data e.g.
graphing, mapping and clustering regional data.
