Map Viewing Service (WMS) of the dataset: Aggregation road noise zones type C index N — Alpes de Haute-Provence

Maps to be produced in the framework of the Strategic Noise Cards (CBS) pursuant to Article 3-II-1°-a of the Decree of 24 March 2006 and the European Directive 2002/49/EC on the management of environmental noise. Noise maps are not prescriptive. Aggregation of generic tables describing the Noise Zones, for an infrastructure, the type of infrastructure concerned ROUTE (R), card type C and index Ln. Approved by prefectural decree of 08/08/2018. Road infrastructure concerned: A51, RN85, RD4, RN4a, RD4b, RD4085, RD4096, RD907 Limit value exceedance maps (or “type c” maps) These are two maps 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). The layers are produced in accordance with the COVADIS standard validated on 29 May 2017. Aggregation obtained by the QGIS MIZOGEO plugin made available by CEREMA. Data source by infrastructure: CEREMA and VINCI for A51 Strategic noise maps are reviewed every 5 years本数据集依据2006年3月24日政令第3-II-1°-a条以及《关于环境噪声管理的2002/49/EC号欧洲指令》的要求，在战略噪声卡（Strategic Noise Cards，CBS）框架下编制完成。噪声地图不具备指令性效力。 本数据集整合了针对各类基础设施的通用噪声分区表格，涉及的基础设施类型为道路（ROUTE，R），地图分类为C型，索引为Ln。 本数据集已于2018年8月8日经省长令批准。 涉及的道路基础设施包括：A51、RN85、RD4、RN4a、RD4b、RD4085、RD4096、RD907。 限值超标地图（或称"C型地图"）共计两幅，用于展示地图编制当年夜间时段（22时至6时）的Ln限值超标区域，其中Ln为夜间噪声水平指标。 所有地图图层均依据2017年5月29日审定通过的COVADIS标准编制完成。 本数据集的整合工作由法国环境与灾害防治研究中心（CEREMA）推出的QGIS MIZOGEO插件完成。 各基础设施对应数据来源：A51路段的数据由CEREMA与万喜（VINCI）提供。 战略噪声地图每5年开展一次定期评审。
