Reach Indexing Tool (RIT)
Training
| [ no slides ] |
[ no video ] |
The Reach Indexing Tool for NHD (NHD-RIT) is an ArcView
extension that allows users to georeference surface water
data (like fish consumption advisories or 305(b) assessments)
to the National Hydrography Dataset. This process of identifying
and assigning surface water ID's or attributes to portions
of NHD is referred to as Reach Indexing. The NHD-RIT training
session includes an overview of how NHD event tables (the
product created by the NHD-RIT) can be used to display surface
water attributes (like assessment or advisory information)
stored in a database. Attendees will learn how to use the
Reach Indexing Tool to create and edit NHD event tables
for linear, point and areal features. The individual tutorials
introduce new users to all of the functionality included
in the NHD-RIT, culminating in a "real world" exercise where
the students must use what they have learned to reach index.
Attendees will also learn how to link georeferenced waters
to a surface water attribute database using ArcView's SQL
Connect feature and Open Database Connectivity (ODBC).
