Water bodies (SVAR2022)

Surface water bodies in water management are those lakes, rivers, coastal waters and lakes that are subject to environmental quality standards. The purpose of these is to be able to compare the assessment of water between different countries and to facilitate the development of reference conditions. SMHI's mission is to identify and designate the water objects as surface water bodies in accordance with principles from the Water Authorities. The Swedish Agency for Marine and Water Management will provide guidance on the mapping. This product, which is based on version SVAR 2022:1.1, consists of 4 layers which are defined or preliminary water bodies. Bodies of water consist of 16647 lines representing watercourses. Seawater bodies consist of 6,925 polygons representing lakes. Coastal waters are the sea areas lying between the coastline and the specific delimitation line (1 nautical mile beyond the baseline). Coastal water bodies consist of 724 polygons representing coastal waters. Overseas waters are the sea areas extending between the special delimitation line and the territorial boundary of the sea (12 nautical miles from the baseline). Seawater bodies consist of 18 polygons representing seawater. Delivery description: https://opendata-download.smhi.se/answer/SVAR_Basic products_2022_1_1.pdf NB! Due to the fact that the geometry of the water bodies is based on data from Lantmäteriet's Hydroproducts, and these products are not open data, SMHI cannot create a WFS service for these.水资源管理范畴内的地表水体，指需符合环境质量标准的湖泊、河流、近岸海域等水体。设立此类标准的目的，在于实现不同国家间水环境评价结果的横向对比，并助力参考基准条件的构建。SMHI的职责是依据水务主管部门的相关原则，对各类水体对象进行识别并划定为地表水体。瑞典海洋与水资源管理局将为该测绘工作提供指导。 本数据集基于SVAR 2022:1.1版本构建，共包含4个图层，分别对应已正式划定或初步划定的水体。 河流水体图层包含16647条代表河道的线要素。 湖泊水体图层包含6925个代表湖泊的面要素。 近岸海域指位于海岸线与特定划定线（领海基线外1海里处）之间的海域。近岸水体图层包含724个代表近岸海域的面要素。 外海海域指位于上述特定划定线与海洋领海边界（领海基线外12海里处）之间的海域。外海水体图层包含18个代表外海海域的面要素。 数据交付说明：https://opendata-download.smhi.se/answer/SVAR_Basic products_2022_1_1.pdf 注意！由于本数据集的水体几何数据基于瑞典土地勘测局（Lantmäteriet）的Hydroproducts水文产品，而此类产品并非开放数据，因此SMHI无法为上述水体创建WFS服务。
