WMS Service (Web Map Service) Surface Water Masses (Polygons) PHC 2015-2021

The WMS (Web Map Service) service called Surface Water Masses (Polygons) PHC 2015-2021 allows the visualisation and consultation of Surface Water Masses with polygon representation, the result of the integration of the information provided by 25 of the 25 Hydrographic Demarcations, in response to Article 13 of the Water Framework Directive. Includes the 7 Demarcations of the Canary Islands. It corresponds to the second cycle Hydrological Plans that were officially approved in January 2016 and incorporates the successive modifications and additions that have undergone until November 2019. Includes data for each mass: code, name, category, naturalness, type, Hydrographic Demarcation, area (measured in Lambert Acimutal Equivalent Area projection). The URL of the WMS Service Masses of Surface Water (Polygons) PHC PHC 2015-2021 is: https://wms.mapama.gob.es/sig/Agua/PHC/MasasAguaSupP2021/wms.aspx The reference systems offered by this service are: — For geographical coordinates: CRS: 84, EPSG: 4230 (ED50), EPSG:4326 (WGS 84), EPSG:4258 (ETRS 89). — For U.T.M coordinates: EPSG:32628 (WGS 84/UTM zone 28N), EPSG:32629 (WGS 84/UTM zone 29N), EPSG:32630 (WGS 84/UTM zone 30N), EPSG:32631 (WGS 84/UTM zone 31N), EPSG:25828 (ETRS 89/UTM zone 28N), EPSG:25829 (ETRS 89/UTM zone 29N), EPSG:25830 (ETRS 89/UTM zone 30N), EPSG:25831 (ETRS 89/UTM zone 31N), EPSG:23028 (ED50/UTM zone 28N), EPSG:23029 (ED50/UTM zone 29N), EPSG:23030 (ED50/UTM zone 30N), EPSG:23031 (ED50/UTM zone 31N).名为“地表水体（多边形）PHC 2015-2021”的Web地图服务（Web Map Service，WMS），可实现地表水体的可视化展示与查询，其数据以多边形形式呈现。该数据集整合了全部25个水文区划提供的信息，以响应《水框架指令》第13条要求，涵盖加那利群岛的7个水文区划。本数据集对应2016年1月正式获批的第二轮水文计划，并纳入了截至2019年11月的所有后续修改与增补内容。 单条水体要素包含以下数据字段：编码、名称、类别、自然属性、类型、所属水文区划，以及采用兰伯特等面积方位投影测算的面积。 本地表水体（多边形）PHC 2015-2021的WMS服务访问地址为：https://wms.mapama.gob.es/sig/Agua/PHC/MasasAguaSupP2021/wms.aspx 该服务支持的坐标参考系统分为两类： — 地理坐标系：CRS:84、EPSG:4230（ED50）、EPSG:4326（WGS 84）、EPSG:4258（ETRS 89） — 通用横轴墨卡托（UTM）坐标系：EPSG:32628（WGS 84/UTM 28N带）、EPSG:32629（WGS 84/UTM 29N带）、EPSG:32630（WGS 84/UTM 30N带）、EPSG:32631（WGS 84/UTM 31N带）、EPSG:25828（ETRS 89/UTM 28N带）、EPSG:25829（ETRS 89/UTM 29N带）、EPSG:25830（ETRS 89/UTM 30N带）、EPSG:25831（ETRS 89/UTM 31N带）、EPSG:23028（ED50/UTM 28N带）、EPSG:23029（ED50/UTM 29N带）、EPSG:23030（ED50/UTM 30N带）、EPSG:23031（ED50/UTM 31N带）
