Datasets:
The NHD datasets supplied
with the NHD Tutorials are not production versions of the data. While
the content of each Tutorial dataset is substantially correct, not all
production steps have been performed on these datasets, making them inappropriate
for any use except with the Tutorials.

Tutorial using free software:
This tutorial is used in conjunction with
ESRI’s ArcExplorer Ver. 2.0 viewing software. ArcExplorer is “freeware” that can be easily
downloaded from the internet. ArcExplorer is a lightweight Geographic Information System
(GIS) data viewer, and has certain limitations. For full NHD viewing and analysis of
tables please complete the ArcView Tutorial. Consult ESRI's information for
minimum hardware and software configuration information.

Requirements:
The NHD Tutorials were developed
using ESRI's ArcView Ver. 3.0 software on the Windows '95 operating system.
You must have ArcView Ver. 3.0 or Ver. 3.1 installed on your PC. Consult
ESRI's information for minimum hardware and software configuration information.
