FWS HQ ES National Wetlands Inventory Active Projects

The U.S. Fish and Wildlife Service (USFWS) is the principal Federal agency that provides information to the public on the extent and status of the Nation’s wetlands. As of May of 2014, the National Wetlands Inventory (NWI) wetland geospatial data layer provides on-line map information for all of the conterminous U.S., Hawaii, Puerto Rico, the Virgin Islands, Guam, the major Northern Mariana Islands and 40% of Alaska. This was accomplished by working with numerous Federal, State, and Tribal agencies as well as various universities and non-governmental organizations. The NWI Program works with these entities to ensure all data meets the federal wetland mapping standard before it get's added into the national wetlands layer. Active mapping projects once completed and pass all NWI QAQC measures are added to the national data layer, and are posted the Wetlands Mapper.美国鱼类及野生动物管理局（U.S. Fish and Wildlife Service, USFWS）是为公众提供美国全国湿地范围与现状信息的核心联邦机构。截至2014年5月，国家湿地普查（National Wetlands Inventory, NWI）的湿地地理空间数据图层，已可为美国本土、夏威夷、波多黎各、美属维尔京群岛、关岛、北马里亚纳群岛主要岛屿以及阿拉斯加40%的区域提供在线地图信息。该数据集的构建依托与众多联邦、州级及部落机构，以及各类高校和非政府组织的合作。国家湿地普查项目会与上述合作主体协同，确保所有数据在纳入国家湿地图层前均符合联邦湿地制图标准。已完成且通过国家湿地普查全部质量保证与质量控制（Quality Assurance/Quality Control, QAQC）流程的活跃制图项目，将被纳入国家数据图层，并发布至湿地地图查看器（Wetlands Mapper）。
