Introduction to the NHD
Training
| [ no slides ] |

The National Hydrography Dataset is a combination of the
USGS 1:100,000 scale hydrography data and the EPA Reach
data. The dataset is structured to allow flow modeling of
the hydrography data and to easily attach agency specific
attribute data to the reaches. The data is in the new USGS
enhanced model, that imports into ArcView.
This class was a hands on introduction to the National
Hydrography Dataset. The topics covered were an indepth
overview of the NHD model, how to download the data from
the website, the steps in loading the data into ArcView
using the NHD toolkit, and example exercises in linking
the NHD with external datasets.
Session was held
at the USGS Office, 8027 Exchange Drive, in Austin
