Washington State: Fish, Stormwater, Pipelines and the National Hydrography Dataset

摘要

Washington State adopted the National Hydrography Dataset (NHD) in January 2011 with the goal of having a single enterprise standard for hydrography (Policy 161.03). Previously, each major natural resource agency in the state was managing its own proprietary hydrography dataset to meet its own business needs, resulting in the duplication of effort and complicating data transfer and analysis among partner agencies. Since the adoption of the NHD standard, the state has focused on associating the highest priority water resources, human health and fisheries datasets with the NHD, correcting the most prominent errors in the data, assisting other government agencies to adopt the NHD and providing access to the NHD for a variety of users.
