Noise footprint of the Finistère land transport infrastructure

Land transport infrastructure sectors classified as noise (railways and roads) in Finistère (including a section straddling Morbihan).
These data apply the Prefectural Decree of the Finistère Sound Classification No 2004-0101 of 12/02/2004 and the Morbihan Decree of 01/12/2003 for the municipality of Guilligomarc’h.
They are segmented by a single sector merged by the municipality concerned.
These areas are not inconstructible, but involve a calculation of acoustic isolation of the facades of the buildings to be built.
They are to be used in conjunction with the axis table (L_CLASSEMENT_SONORE_2004_S_029).
These are the latest data available to date.

法国菲尼斯泰尔省（含跨莫尔比昂省的一段区域）内被划为噪声管控类别的陆路交通基础设施区段（涵盖铁路与道路）。
本数据集遵循2004年2月12日发布的《菲尼斯泰尔省声环境分类第2004-0101号省政令》，以及针对吉戈马尔克（Guilligomarc’h）市镇的2003年12月1日莫尔比昂省政令。
本数据集以相关市镇合并后的单一区段为单位进行分割标注。
该类区域并非禁止建设，但需对拟建建筑的外立面开展声隔声性能计算。
本数据集需与轴线数据表L_CLASSEMENT_SONORE_2004_S_029配合使用。
本数据集为截至目前可获取的最新版本数据。
