Data Source

Important Note:

This map is hosted on a remote server where boydsmaps has no control over its availability or performance. We have already discontinued our other remotely-hosted maps but will continue offering maps from USGS servers as long as they work properly at boydsmaps.

But please realize, these remotely-hosted USGS maps could be permanently discontinued at any time without notice if there are problems. Our mission is offering maps of the Northeastern United States that are hosted on our own server where we can assure their quality.

Description

UThe USGS NHDPlus High Resolution service, NHDPlus_HR, a part of The National Map, is a comprehensive set of digital spatial data comprising a nationally seamless network of stream reaches, elevation-based catchment areas, flow surfaces, and value-added attributes that enhance stream network navigation, analysis, and data display.

NHDPlus High Resolution (NHDPlus HR) is a scalable geospatial hydrography framework built from the high resolution National Hydrography Dataset, nationally complete Watershed Boundary Dataset, and 3D Elevation Program (3DEP) ? arc-second (10 meter ground spacing) digital elevation model data. The National Map download client allows free downloads of public domain NHDPlus HR data in Esri File Geodatabase format. For additional information on the NHDPlus HR, go to www.usgs.gov/core-science-systems/ngp/.

Data refreshed August 2020.
