INSPIRE Download Service (predefined ATOM) for data set Noise level AggRoad L_Den 2017 in Saarland

Description of the INSPIRE Download Service (predefined Atom): The noise index LDEN reflects the noise exposure for the whole day (24 hours) and is used for the preparation of strategic noise maps. These isophone maps show the calculation results of the environmental noise mapping 2017 on the main roads in the agglomerations of the Saarland (the state capital Saarbrücken is designated as an agglomeration). In accordance with § 4(4) of the 34. BImSchV shows the noise situation for the LDEN in the following isophone bands with a class width of 5 dB: 55 dB(A) LDEN 60 dB(A), 60 dB(A) LDEN 65 dB(A), 65 dB(A) LDEN 70 dB(A), 70 dB(A) LDEN 75 dB(A) and 75 dB(A) LDEN. The noise maps must be reviewed and, if necessary, revised every five years. The central nationwide strategic noise mapping of major roads in the Saarland was commissioned by the Saarland City and Municipal Council for the affected and responsible cities and municipalities. The Ministry of the Environment and Consumer Protection has contributed proportionally to the costs and coordinated the mapping. - The link(s) for downloading the dataset(s) is/are dynamically generated from a metadata set欧洲空间信息基础设施（INSPIRE）下载服务（预定义Atom）说明：噪声指数LDEN反映了全天（24小时）的噪声暴露水平，用于战略噪声地图的编制工作。此类噪声等值线地图展示了2017年萨尔州（其州府萨尔布吕肯被划定为聚居区）各聚居区内主要道路的环境噪声测绘计算结果。根据第34章《联邦污染防治法》（BImSchV）第4条第4款，本数据集以5dB为级差，将LDEN噪声状况划分为以下等响区间：55 dB(A) ≤ LDEN < 60 dB(A)、60 dB(A) ≤ LDEN < 65 dB(A)、65 dB(A) ≤ LDEN < 70 dB(A)、70 dB(A) ≤ LDEN < 75 dB(A)以及LDEN ≥ 75 dB(A)。此类噪声地图需每五年进行一次复核，必要时予以修订。针对萨尔州主要道路的全国性战略噪声测绘项目，由萨尔州城市与市政委员会委托受影响且承担相应责任的各城市及市镇负责实施。环境与消费者保护部按比例承担了相关成本，并对测绘工作进行了协调。——数据集下载链接均由元数据集动态生成。
