NHD Network Builder, VBET and Valley Bottom Editing

This page contains instructional videos to help users download and run two ArcGIS tools: the NHD Network Builder tool and the V-BET (Valley Bottom Extraction Tool) as well as instructions on how to edit valley bottoms. Additional instructional documentation can also be downloaded at the bottom of the page.  This documentation includes specifications about data types and projections that should be used for the inputs of the tools.

The video below is 5:46 minute instructional video on NHD Network Builder and covers:
  • Downloading the most recent NHD data from the USGS website.
  • Downloading the toolbox containing the NHD Network Builder from a BitBucket repository.
  • Loading the toolbox into ArcMap.
  • Step by step instructions for running the tool.
  • A discussion on the tools output, and how the output can be changed to meet user needs or preferences.

The video below is a 7:09 minute instructional video on V-BET and covers:
  • Downloading the toolbox containing the V-BET tool from a BitBucket repository.
  • Loading the toolbox into ArcMap.
  • The inputs required to run V-BET.
  • Step by step instructions for running V-BET.
  • Settings that can be adjusted when running V-BET to refine the output.
  • Optional settings and their utility.
  • Display and discussion of valley bottom output for the Middle Fork John Day River.

VBET Instructions


The video below is a 8:41 minute instructional video on valley bottom editing and covers:
  • Base layers used to guide the editing process.
  • Brief description of what a valley bottom is.
  • The three stages of valley bottom editing.
  • Instructions on valley bottom editing.
It's worth noting that if the valley bottom shapefile is very large, editing can become slow and clunky.  In this case it helps to convert the polygon to a polyline and edit the line.  After editing is complete the line can be converted back to a polygon.
