Notes

Before downloading, please note:

To decompress the Zipped files, you will need a decompression program, such as WinZip or PKZip. These shareware programs are available from download sites such as CNET.com

For GIS data:

These data (as well as most GIS programs and viewers) were developed on PC Windows-based machines and may not be usable on other platforms.
To view these files, you will need a GIS program such as ArcView, ArcInfo, or MapInfo. If you don't have a GIS program, you may download ArcExplorer, ESRI's FREE GIS data viewer.
These files are quite large, even in compressed format. Please make sure you have the proper media space to store them and recognize that downloading may take some time.

For GPS data:

To use these data, you will need (1) a GPS unit that has upload/download capabilities, and (2) a PC-to-GPS interface data cable so that you may transfer the data. Please check your GPS manual to see if your unit is capable of uploading/downloading data and to make sure you have the proper equipment.
To transfer these data to a GPS unit, you will also need a GPS mapping program such as National Geographic's TOPO! or MapTech's Terrain Navigator.
If you do not have a GPS mapping program, you may download one of the following FREE programs that work with most Garmin, Magellan, and Lowrance/Eagle GPS units: GPS TrackMaker, EasyGPS, or G7ToWin.
