Abstract – The USGS has just released the first NHDPlus High Resolution (NHDPlus HR) datasets in Beta version for seven hydrologic regions covering a quarter of the conterminous U.S. NHDPlus HR extends the rich attribution and functionality present in the NHDPlus Version 2 to the spatial accuracy and detail present in the high resolution National Hydrography Dataset and 1/3 arc-second 3D Elevation Program data. For more information, please see the NHDPlus High Resolution page.

Topics will include:

  • Overview: What is NHDPlus HR, what does Beta mean, what you can do with it, and how it improves upon the NHDPlus Version 2
  • Data availability: Production and release plans
  • How to download: TNM Download viewer, FTP and Cloud folders
  • What comes after Beta: The NHDPlus HR Refresh concept, Beta QC and Markup tool overview
  • Learn about the VisibilityFilter Attribute: The ability to represent the data at different scales, currently populated for testing in Regions 01 and 06
