Open water for King County and portions of adjacent counties

For more information about this layer please see the GIS Data Catalog. Open water features, both natural and anthropic, for King County and portions of adjacent counties. Features can be displayed as water or non water to distinguished between water and land. FEAT_TYPE item defines multiple classes of features, primarily lakes/ponds and streams rivers. Puget Sound and significant double-banked streams and rivers are shown, plus a limited number of manmade features such as aqueducts, ditches, channels and flumes. Areal open water features are mainly differentiated as either Lakes/Ponds or Impoundments roughly defined as natural and anthropic, respectively. This layer includes wetlands only to the extent that the open water portion of emergent wetlands is mapped. A value in the STATUS item indicates whether the water feature is associated with a wetland, dependent on best available ancillary data and orthoimagery. The name of features, where available, is included. By using the SUBSET item the layer can be defined to show only the larger water bodies and rivers.如需了解该图层的详细信息，请查阅地理信息系统（GIS）数据目录。本数据集涵盖金县及部分邻近县域内的自然与人工开放水域要素。可将要素以水域或非水域模式渲染，以区分水体与陆地。要素类型（FEAT_TYPE）字段定义了多类要素，主要涵盖湖泊/池塘以及溪流、河流。本图层包含普吉特湾（Puget Sound）、重要复式河道溪流，同时收录少量人工设施要素，例如渡槽、沟渠、渠槽与引水槽。面状开放水域要素主要分为两类：湖泊/池塘与拦蓄水体（Impoundments），二者大致分别对应自然形成与人工建造的水域。本图层仅纳入已完成制图的挺水湿地（emergent wetlands）开放水域部分。状态（STATUS）字段的取值可指示该水域要素是否与湿地相关联，该判断基于当前可获取的最佳辅助数据与正射影像（orthoimagery）。若有可用信息，将一并标注要素名称。通过设置子集（SUBSET）字段，可将本图层限定为仅展示大型水体与河流。
