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》将湿地定义为："无论是否被开发利用，通常被淡水、盐水或咸淡水永久或临时淹没或覆盖的土地；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157号《农村地区发展法》的第127、128条也对湿地作出了提及（其中包括在《环境法典》中新增第L.211-1-1条）。
实际操作中，湿地的认定（在成果呈现维度也称为"湿地制图"）由流域、大区乃至省级行政单位，在相关管理机构、区域环境与空间农业林业局（DREAL）或省级主管部门的监督下推进。因此湿地的数据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。桑德斯通（Sandstone）已编制《湿地名录（Wetland Inventory）》手册，列明湿地描述的通用核心要素，以实现信息交互与数据共享。
