Description: This image of the United States of America at night is a composite assembled from data acquired by the Suomi NPP satellite in April and October 2012. The VIIRS Plus DMSP Change in Lights (VIIRS+DMSP dLIGHT) data set fuses nighttime lights imagery from the U.S. Air Force Defense Meteorological Satellite Program (DMSP) Operational Linescan System (OLS) with a stable night light composite from the next generation Suomi National Polar-orbiting Partnership (NPP) Visible Infrared Imaging . nightlightstats. The technique of collecting and operationalizing satellite night lights data itself is rather young. Night lights, as detected by satellites, are increasingly used by economists, typically as a proxy for economic activity. Light Every Night - New nighttime light data set and tools for development • How night lights data is being applied to - urban studies - disaster monitoring - COVID-19. The data were acquired over nine days in April 2012 and 13 days in October 2012. The map is useful to identify the areas of poverty in the world, where economic activity is limited. The nighttime light (NTL) satellite data have been widely used to investigate the urbanization process. 10 months ago. Beware The Charms Of Satellite Map Data | Mint Satellite data for the social sciences: measuring rural electrification with night-time lights. It was found that in the case of a large city such as Cracow, turning off all street lighting reduces the amount of light energy radiated into the sky by about 50% . Our Earth, at night - National Oceanic and Atmospheric Administration The fact that satellite data are unbiased, have a high spatial resolution, are collected frequently and can be obtained at low cost make them attractive. However, there are few studies focusing on the spatialised mapping of the GDP at pixel level and further analysis of the economic differences in agricultural and non-agricultural sectors for the different regions using the VIIRS-NPP data.
