公司夜灯光数据

公司夜灯光数据库利用空间分辨率约500米，重返周期为1天的遥感卫星图像反演出夜灯光。该数据库基于高频卫星遥感图像与高精度公司电子围栏，结合地理空间信息处理技术，通过云计算平台自动获取公司夜灯光数据。灯光变化反映着企业夜间生产办公活动的强度，为全面了解企业生产经营情况提供了另类视角。团队通过云计算技术和自主算法，解译了百万量级的卫星遥感图像，可以提供全国约3000家制造业上市公司自2013年起的日度、月度、季度和年度夜灯光数据。

The Corporate Nighttime Light Database retrieves nighttime light data from remote sensing satellite imagery with a spatial resolution of approximately 500 meters and a 1-day revisit period. Built on high-frequency remote sensing satellite imagery and high-precision corporate electronic fences, the database automatically acquires corporate nighttime light data through cloud computing platforms combined with geospatial information processing technologies. Variations in nighttime light intensity reflect the scale of enterprises' nighttime production and office activities, offering an alternative perspective for comprehensively understanding enterprises' production and operational conditions. The research team has interpreted millions of satellite remote sensing images using cloud computing technologies and proprietary algorithms, and is able to provide daily, monthly, quarterly and annual nighttime light data for approximately 3,000 publicly listed manufacturing companies across China since 2013.
