Simple download service (Atom) of the dataset: Aggregation generic tables noise zones type C index Ln in Héault

Aggregation of generic tables describing the Noise Zones for all terrestrial infrastructure, map type C and Ln index. Exceedance maps of limit values: maps to be made within the framework of the CBS pursuant to Article 3-II-1°-c of the Decree of 24 March 2006. This is a dataset representing the areas where the Ln limit values are exceeded for the year in which the maps are drawn up. LN noise level indicator for the night period (22h-6h). Aggregation obtained by the QGIS MIZOGEO plugin made available by CEREMA. Data source by infrastructure: CEREMA.本数据集汇总了覆盖所有陆地基础设施、C类地图及Ln索引（Ln index）的噪声分区通用表格。 限值超标地图： 此类地图需依据2006年3月24日颁布的法令第3-II-1°-c条，在CBS框架下制作完成。本数据集用于表征地图编制当年Ln限值超标区域。 Ln（即LN）： 为夜间时段（22时至6时）的噪声级指标。 本汇总成果由CEREMA提供的QGIS MIZOGEO插件生成。 基础设施类数据来源：CEREMA。
