This is a fantastic overview of the Black Marble dataset! The way NASA uses the VIIRS day-night band to filter out stray light and moonlight is incredible. From a GIS perspective, do you find that processing this data for tracking urban sprawl requires heavy custom filtering, or are the pre-processed layers clean enough for immediate spatial analysis?
