灯光指数数据

灯光指数数据包括：针对全国各省市（31个省、自治区、直辖市）的夜光遥感卫星数据，以月为单位，按照数据的时间和区域需求，提供经处理加工后的卫星影像数据，利用算法模型获取区域的灯光像元总数及灯光亮度值，计算各地区的区域亮度均值(ALI)和区域亮度总值（NTL），形成专题图及数据报告。The nighttime light index dataset encompasses nighttime light remote sensing satellite data covering all 31 provinces, autonomous regions, and municipalities directly under the Central Government of China. On a monthly basis, preprocessed satellite image data is provided in accordance with the temporal and regional requirements of the dataset. Utilizing algorithmic models, the total count of nighttime light pixels and their brightness values within each region are extracted. Subsequently, the Regional Average Light Index (ALI) and Total Nighttime Light (NTL) for each region are calculated, and thematic maps and data reports are generated accordingly.
