摘要: The authors report on a systematic ground-based validation of DMSP-OLS night lights imagery to detect rural electrification in Vietnam. Based an original survey village-level units Vietnam, this study compares nighttime light output from the U.S. Air Force Defense Meteorological Satellite Program’s Operational Linescan System (DMSP-OLS) against data electrical infrastructure and electricity use 200 electrified villages. Monthly annual composites record one-point increase brightness along DMSP-OLS’s 63-point scale for every 60–70 additional street or 240–270 homes. Using time series 90 nightly images, show 125–200 streetlights, 550–700 results highlight potential support efforts connect 1.2 billion people who lack around world.
