Waterway Network Nodes
收藏资源简介：
Waterway Network Nodes This National Geospatial Data Asset (NGDA) dataset, shared as a United States Army Corps of Engineers (USACE) feature layer, displays navigable waterway nodes. Per USACE, The National Waterway Network (NWN) “is comprised of a link database and a node database. Nodes may represent physical entities such as river confluence's, ports/facilities, and intermodal terminals, USACE nodes, or may be inserted for analytical purposes (i.e., to facilitate routing).” Waterway Node 34580 (Washington, D.C.) Data currency: current federal service (Waterway Network Node) NGDAID: 154 (Navigable Waterway Nodes (National) - National Geospatial Data Asset (NGDA) Waterway Nodes) For more information, please visit: Definition of Navigable Waters of the US For feedback please contact: Esri_US_Federal_Data@esri.com NGDA Data Set This data set is part of the NGDA Transportation Theme Community. Per the Federal Geospatial Data Committee (FGDC), Transportation is defined as the "means and aids for conveying persons and/or goods. The transportation system includes both physical and non-physical components related to all modes of travel that allow the movement of goods and people between locations".

航道网络节点 本数据集为美国国家地理空间数据资产（National Geospatial Data Asset, NGDA）项目成果，以美国陆军工程兵团（United States Army Corps of Engineers, USACE）要素图层形式共享，用于展示可通航航道节点。 据美国陆军工程兵团定义，国家航道网络（National Waterway Network, NWN）“由链路数据库与节点数据库共同构成。节点可代表各类物理实体，如河流汇流处、港口/设施及多式联运枢纽、美国陆军工程兵团专属节点，也可出于分析目的（即助力路径规划）人工增设。” 示例航道节点：编号34580的华盛顿特区航道节点。数据时效性：当前联邦服务更新版（航道网络节点）。NGDA编号：154（全国可通航航道节点 - 美国国家地理空间数据资产航道节点数据集） 如需了解更多信息，请访问：美国通航水域定义 如需反馈，请联系：Esri_US_Federal_Data@esri.com 本数据集隶属于NGDA交通主题社区。根据美国联邦地理数据委员会（Federal Geospatial Data Committee, FGDC）的定义，交通“是指用于运送人员及/或货物的手段与工具，交通系统涵盖与各类出行方式相关的物理与非物理组件，支持人员与货物在不同地点间的流转”。 如需获取其他NGDA相关内容，请访问：Esri联邦数据集
