Core Insights - The Shenzhen Ecological Environment Monitoring Center has developed the first high-precision light pollution map in China, utilizing high-resolution remote sensing satellite data and AI algorithms [1] Group 1: Light Pollution Monitoring - The new light pollution map integrates three key indicators: vertical illuminance, glare index, and night sky brightness, facilitating a comprehensive assessment of urban light environments [1] - This map serves as both a "diagnostic report" for urban light environments and a "navigation map" for precise governance and scientific light control [1] Group 2: Technological Innovation - Traditional methods of monitoring light pollution relied on ground-based measurements, which are costly, time-consuming, and limited in coverage, making it difficult to capture dynamic distributions and trends in complex urban structures [1] - The project team employed multi-source remote sensing data fusion technology combined with AI algorithms to effectively incorporate geographical spatial information into nighttime lighting models, overcoming interference from weather conditions [1] - Compared to traditional ground-based monitoring, the new approach can reduce monitoring costs by approximately 75% and labor costs by nearly 80%, providing a technical guarantee for understanding the overall pattern of urban light pollution [1]
