Dataset Direct Download Service (WFS): AGREGATION of Type C Strategic Noise Cards with a large common track infrastructure.

The European Directive 2002/49/EC on the assessment and management of environmental noise aims at a harmonised assessment of exposure to noise in the Member States. It defines them as representations of data describing a noise situation according to a noise indicator, indicating exceedances of limit values, the number of persons exposed. Noise maps are not prescriptive. These are information documents that are not legally enforceable. As graphic elements, however, they can supplement a Local Planning Plan (LDP). As part of an Urban Travel Plan (UDP), maps can be used to establish baselines and target areas where better traffic management is needed. Carried out pursuant to Article 3-II-1-b of the Decree of 24 March 2006, the map represents the areas where the Lden and Ln boundaries are exceeded. — LD (Lden) Sound level indicator means Level Day-Evening-Night. — LN (Ln) Sound level indicator for the night period between 22.00 and 06:00. Aggregation carried out with the QGIS MIZOGEO plugin made available by CEREMA. Data source: CEREMA《欧盟2002/49/EC号环境噪声评估与管理指令》旨在实现欧盟成员国间噪声暴露评估的统一协调。该指令将噪声地图定义为：依据特定噪声指标表征噪声现状、标注限值超标情况及受噪声暴露人口数量的数据载体。 噪声地图不具有规范性效力，仅为不具备法律强制执行力的参考文档。但作为可视化图表元素，其可作为地方规划方案（Local Planning Plan, LDP）的补充材料。 在城市交通规划方案（Urban Travel Plan, UDP）的编制框架中，噪声地图可用于确立基线基准，并识别亟需优化交通管理的目标区域。 本数据集依据2006年3月24日颁布的法令第3-II-1-b条制作，所呈现的地图标注了Lden与Ln声级限值的超标区域。 — LD（Lden）声级指标：指昼间-夜间等效声级（Day-Evening-Night）。 — LN（Ln）声级指标：指22:00至06:00夜间时段的声级。 数据聚合工作由CEREMA推出的QGIS MIZOGEO插件完成。 数据来源：CEREMA
