Noise Level Measurements in Lisbon

Overview This feature service provides detailed geospatial data on noise levels measured across Lisbon, Portugal, during 2021. It offers an important resource for analyzing environmental noise pollution within the city, highlighting variations in sound intensity across different grid areas. Feature Layers Noise Level: This layer represents mean noise levels registered during the day, afternoon, and night (Lden), recorded in weighted decibels. The data is organized by geographic grid cells, allowing spatial analysis of noise distribution patterns within Lisbon. The layer's attributes also include identifiers and geometric measurements, which facilitate integration with other spatial datasets and support detailed spatial queries. Geographic Coverage The dataset covers the area of Lisbon within Portugal, providing localized environmental information relevant to urban planning, public health, and noise management strategies in this specific region. Use Cases Environmental noise monitoring and management by local authorities. Urban planning and development assessments considering noise pollution impacts. Research studies focused on public health, quality of life, and urban acoustics.概述 本要素服务提供葡萄牙里斯本2021年全域实测噪声水平的详细地理空间数据，可为该市环境噪声污染分析提供关键支撑，清晰展现不同网格区域内的声强差异。要素图层 噪声水平图层：该图层呈现日间、午后及夜间测得的昼间-傍晚-夜间等效声级（Lden），单位为加权分贝。数据按地理网格单元进行组织，支持对里斯本市内噪声分布模式开展空间分析。该图层的属性字段还包含标识符与几何测量信息，便于与其他空间数据集集成，并可支撑精细化空间查询。地理覆盖范围 本数据集覆盖葡萄牙里斯本全域，提供本地化环境信息，可服务于该区域的城市规划、公共卫生及噪声治理策略制定。应用场景 1. 地方当局开展环境噪声监测与治理工作；2. 纳入噪声污染影响评估的城市规划与开发项目论证；3. 聚焦公共卫生、生活质量及城市声学的相关研究。
