Map Viewing Service (WMS) of the dataset: Cantal surfacing wetland

In the legal sense, the Water Act of January 1992 defines wetlands as “land, whether or not exploited, usually flooded or engrown with fresh water, salted or brackish permanently or temporarily; vegetation, where it exists, is dominated by hygrophilic plants for at least part of the year”. They are also mentioned in articles 127 and 128 of Law 2005-157 on the development of rural territories (including the addition of an article L. 211-1-1 to the Environmental Code).In practice, their determination (also called “cartography” in terms of rendering) is carried out locally at the level of the basin, the region, or even the department under the supervision of the Agency, the DREAL or a departmental authority... Their suppliers and descriptions may therefore be diverse.Not included here are the so-called Ramsar areas.The Sandstone has established a dictionary “Wetland Inventory” listing the elements of a common core of their description, allowing information exchange and data sharing.

从法律规制视角来看，1992年1月颁布的《水法》将湿地（wetland）定义为：“无论是否被开发利用，通常被淡水、咸水或半咸水永久或暂时性淹没或浸渍的土地；若存在植被，则一年内至少有一段时间以湿生植物为优势群落”。2005年第2005-157号《农村地区发展法》的第127、128条也对湿地作出了相关规定，其中还包括为《环境法典》新增第L.211-1-1条这一内容。在实际操作中，湿地的划定（在成果呈现层面也可称为“专题制图”）由流域、大区乃至省级层面的地方机构执行，监管主体为主管机构、地区环境与可持续发展局（DREAL）或省级主管部门……因此，湿地数据的来源与描述方式可能存在多样性。本次数据集未纳入所谓的拉姆萨尔（Ramsar）湿地区域。砂岩（Sandstone）已编制《湿地清查（Wetland Inventory）》，列明了湿地描述的通用核心要素，以促进信息交流与数据共享。
