中国高质量夜间灯光数据

中国高质量夜间灯光数据是CnOpenData与吉林高分遥感应用研究院有限公司合作的数据库 ，基于多源夜间灯光卫星遥感影像，经过科学手段对数据进行降噪、修正、分析统计，以年度、月度为更新频率，以省市县三级行政区划作为统计单元，制作高质量夜间灯光数据。数据包括：Excel统计表和Shp矢量文件两种形式，内容包括：+总亮度值、总像元数、平均亮度值、发光像元数、发光像元平均值、发光像元占比。  高质量夜间灯光数据能够提供关于人类活动和城市发展的有价值的信息，对城市规划、经济研究和灾害监测等方面具有重要的意义和作用：

China High-Quality Nighttime Light Dataset is a database jointly developed by CnOpenData and Jilin Gaofen Remote Sensing Application Research Institute Co., Ltd. Built upon multi-source nighttime light satellite remote sensing imagery, this dataset undergoes scientific processing including noise reduction, correction, analysis and statistical calculation, with annual and monthly update cycles, and adopts the three-level administrative divisions of province, city and county as statistical units for data production. The dataset is available in two formats: Excel statistical tables and Shapefile (SHP) vector files, and includes the following metrics: total brightness value, total number of pixels, average brightness value, number of luminous pixels, average value of luminous pixels, and proportion of luminous pixels. This high-quality nighttime light dataset can provide valuable insights into human activities and urban development, and holds significant importance for urban planning, economic research, disaster monitoring and other relevant fields:
