PHC Hydrographic Network 2022-2027

Hydrographic network formed by the union of water bodies third cycle hydrological plans (2022-2027). The geometry of lakes, transitional and coastal water bodies are represented as polygons. The geometry of the river water mass can be represented by a polygon or a polyline. These elements are modeled as segments or sections and nodes, real and fictional, with a view to giving it continuity to allow cartographic use, as a hydrographic network to handle them in hydrological analysis. The dataset is the result of the integration of the information provided by the 25 Hydrographic Districts, in response to Article 13 of the Water Framework Directive. It includes information on the 14 plans approved in the Council of Ministers on 24 January 2023 (the 12 intercommunal basins, the Balearic Islands and Galicia Costa) and of the other plans still pending approval in the version of the latest available documents. These last plans are those of the 7 Demarcations of the Canary Islands, Catalonia and the 3 Andalusian demarcations. The structure of the data is specified by the reporting guidelines of the Water Framework Directive, which can be consulted at https://cdr.eionet.europa.eu/help/WFD/WFD_780_2022. This information meets the obligations of Article 13 of Directive 2000/60/EC and is therefore included in the list of ‘high value data’ sets as environmental water data, as set out in Regulation 2023/138 of 21 December 2022 establishing a list of specific high value data sets and modalities for publication and re-use, in the framework of Directive 2019/1024 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 20 June 2019 on open data and the re-use of public sector information. This information is part of the national spatial reference data under Directive 2007/2/EC (INSPIRE). It has been produced in collaboration and coordinated between the different cartographic and hydrological organisms at the national and regional levels.本数据集对应的水文河网由第三轮水文规划（2022-2027）中的各类水体整合构建。湖泊、过渡性水体及近岸海域水体的空间几何形态以多边形要素表示；河流水体的空间几何形态可采用多边形或折线要素进行表达。上述要素以分段/断面及节点（含真实节点与虚拟节点）进行建模，以保障河网的连续性，满足制图应用需求，并可用于水文分析场景。 本数据集整合了25个水文分区提交的信息，以响应《水框架指令》（Water Framework Directive）第13条要求。数据集涵盖2023年1月24日经部长理事会批准的14项规划信息（含12个跨区域流域、巴利阿里群岛及加利西亚沿海流域），以及最新可用文档版本下仍待审批的其余规划数据；上述待审批规划涵盖加那利群岛的7个辖区、加泰罗尼亚，以及安达卢西亚的3个辖区。数据集的数据结构遵循《水框架指令》的报告指南，相关指南可通过链接https://cdr.eionet.europa.eu/help/WFD/WFD_780_2022查阅。 本数据集符合欧盟指令2000/60/EC第13条的相关义务要求，因此被纳入《高价值数据集名录》中的环境水体数据类别；该名录由2022年12月21日发布的2023/138号法规确立，规定了特定高价值数据集的范围、发布及再利用方式，其制定依据为2019年6月20日欧盟议会与理事会发布的关于开放数据及公共部门信息再利用的指令2019/1024。 本数据集属于欧盟指令2007/2/EC（INSPIRE，欧洲空间信息基础设施）规定的国家空间参考数据范畴，由国家级与区级各类制图及水文机构协同合作、统筹编制完成。
