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：

The high-quality nighttime light dataset of China is a collaborative database jointly developed by CnOpenData and Jilin Gaofen Remote Sensing Application Research Institute Co., Ltd. Based on multi-source nighttime light satellite remote sensing images, it undergoes scientific processing including data denoising, correction, analysis and statistics, with annual and monthly update cycles, and uses the three-level administrative divisions of province, city and county as statistical units to generate the final high-quality nighttime light dataset. The dataset is available in two formats: Excel statistical tables and Shapefile (SHP) vector files, and the included content covers total brightness value, total number of pixels, average brightness value, number of luminous pixels, average brightness of luminous pixels, and proportion of luminous pixels. This high-quality nighttime light dataset provides valuable information about human activities and urban development, and plays an important role in fields such as urban planning, economic research and disaster monitoring.
