Dataset Direct Download Service (WFS): Mapping of rivers and non-stream water points in Puy-de-Dôme

Mapping of rivers and non-stream water points in Puy-de-Dôme prepared in accordance with the Government Instruction of 3 June 2015 on the mapping and identification of rivers and their maintenance and the Ministerial Orders of 04/05/2017 and Prefectural of 05/07/2017 on untreated areas. Based on the definition of the watercourse (constitutes a stream, a flow of running water in a natural bed originally fed by a source and having a sufficient flow of much of the year) and the definition of water points (spray, beef and water body), a mapping project is proposed in the interactive map classifying the hydrographic sections and water surfaces of the IGN TOPO BD into four categories: — watercourses for the application of Articles L214-1 to L214-6 of the Environmental Code — the sections that need to be examined to determine whether they meet the definition of watercourse — non-stream water points for which an untreated area is to be set up — non-stream sections that need to be examined to determine whether they meet the definition of a water point within the meaning of the untreated area Based on the definition of the watercourse (constitutes a stream, a flow of running water in a natural bed originally fed by a source and having a sufficient flow of much of the year) and the definition of water points (spray, beef and water body), a mapping project is proposed in the interactive map classifying the hydrographic sections and water surfaces of the IGN TOPO BD into four categories: — watercourses for the application of Articles L214-1 to L214-6 of the Environmental Code — the sections that need to be examined to determine whether they meet the definition of watercourse — non-stream water points for which an untreated area is to be set up — non-stream sections that need to be examined to determine whether they meet the definition of a water point within the meaning of the untreated area本数据集为多姆山省（Puy-de-Dôme）内河流与非河道水体点位的测绘成果，编制依据为2015年6月3日发布的《关于河流测绘、识别与养护的政府指令》，以及2017年5月4日、2017年7月5日分别发布的针对未处理区域的部令与省督令。 基于河道的定义（即天然河床中由泉源补给、全年多数时段具备充足流量的径流）与水体点位的定义（包括泉眼、池塘与自然水体），本交互式地图测绘项目将法国国家地理研究院（Institut Géographique National, IGN）TOPO基础数据库（TOPO BD）中的水文河段与水面划分为四类： — 适用《环境法典（Environmental Code）》第L214-1条至第L214-6条的河道 — 需开展核查以判定是否符合河道定义的河段 — 需划定未处理区域的非河道水体点位 — 需开展核查以判定是否符合未处理区域范畴内水体点位定义的非河道河段 基于河道的定义（即天然河床中由泉源补给、全年多数时段具备充足流量的径流）与水体点位的定义（包括泉眼、池塘与自然水体），本交互式地图测绘项目将法国国家地理研究院（Institut Géographique National, IGN）TOPO基础数据库（TOPO BD）中的水文河段与水面划分为四类： — 适用《环境法典（Environmental Code）》第L214-1条至第L214-6条的河道 — 需开展核查以判定是否符合河道定义的河段 — 需划定未处理区域的非河道水体点位 — 需开展核查以判定是否符合未处理区域范畴内水体点位定义的非河道河段
