Simple download service (Atom) of the dataset: Rail noise zone for Type A maps Lden indicator for the 3 rd deadline in Maine-et-Loire(49)

Aggregation of generic tables describing the Noise Zones, for an infrastructure, type of infrastructure concerned FER (F), type A map according to the Lden indicator (day/evening/night). This map is a graphic representation that locates areas exposed to noise using isophone curves ranging from 55 dB to 75 dB and more, by step of 5 dB. Map to be made under the CBS under Articles R.571-37 and R.571-38 of the Environmental Code. Aggregation obtained by the QGIS MIZOGEO plugin made available by CEREMA.本数据集为针对基础设施的噪声分区通用表格汇总，所涉基础设施类型为FER（法国），系依据Lden指标（昼/傍晚/夜间）编制的A型噪声地图。该地图为可视化定位受噪声影响区域的图形化呈现，通过以5dB为步长、覆盖55dB至75dB及以上的等噪声线（isophone curves）划定受影响区域。本地图需依据《环境法典》（Environmental Code）第R.571-37条与第R.571-38条规定，在CBS框架下编制。本数据集的汇总结果由CEREMA发布的QGIS MIZOGEO插件生成。
