Dataset Direct Download Service (WFS): Water — Warning zone for surface waters during droughts in Loir-et-Cher

This layer is used to feed a national layer. It is produced locally in each DDT and then assembled at regional level before transmission at the national level (Water and Biodiversity Directorate). As the management of drought orders is departmental, the alert zones will all stop at departmental boundaries. The interdepartmental areas will be “cut” and bear a name as close as possible. The superficial alert zones will not overlap under any circumstances. — name of fields: 1) Id: Identifier consisting of characters, in the form <[INSEE code of the region] >_<[NiNsee Dpt]>_<[Ndorder]> this identifier must be unique (A each field corresponds to one code and only one), and no duplication of the latter. 2) Dpt: No of department No. Insee of the department consisting of 2 digits for the departments of metropolis, with the exception of the departments of Corsica 2A and 2B. 3) Libel_ZA_ESU (or Libel_ZA_ESO) alerte:constitué characters, in the form “X basin”, “X table”, “X basin from A to B”, etc.本图层用于支撑国家级图层。其由各DDT本地生成，随后在区域层面完成整合，最终上传至国家级层面（数据来源：水资源与生物多样性总局（Water and Biodiversity Directorate））。 由于干旱预警等级的管理实行省级负责制，因此所有预警区域均不得跨越省界。省际区域将被“切割”，并采用尽可能贴合其范围的名称。无论何种情况，表层预警区域均不得出现重叠。 — 字段说明： 1) Id：标识符由字符组成，格式为<[地区INSEE代码]>_<[省INSEE代码]>_<[干旱等级编号]>。该标识符需具备唯一性（每个字段对应且仅对应一个编码），不得出现重复编码。 2) Dpt：省编号，即法国本土省份的INSEE代码为2位数字，科西嘉省（2A、2B）除外。 3) Libel_ZA_ESU（或Libel_ZA_ESO） alerte：由字符构成，格式可采用"X流域"、"X台地"、"X流域A至B段"等形式。
