However, you should be aware of the following. In most cases these gpx files cannot simply be uploaded to your GPS device because there are probably more than the 20 track limit allowed for Garmin devices. I do not know what the limits are for other devices.
This is primarily because the gpx files were used to create maps of extensive trail systems. This often involved multiple mapping sessions and multiple GPS tracks. As well, to avoid track overlap, particularly with my first GPS unit which was not as accurate as my current one, it was necessary to break up the tracks used to record the trails. Often editing of the tracks created very many separate track files.
The best way to use the gpx files is to load them onto software such as Garmin MapSource. You can then create new tracks of your planned route by tracing over the tracks on the map and upload those tracks to your GPS unit. That is the method that I use and it works very well. Note that this does not work very well if you use "white" tracks that blend in with the the MapSource background.
If you do not have a GPS unit you can still use the gpx files by loading them onto software that has background maps, such as TopoFusion, or Google Earth, and see the detailed tracks over the maps or satellite image.
If you do download the gpx files please email me at richardw.woodley@gmail.com and let me know so that I have an idea of how many people are downloading and using the files. They can be downloaded by clicking the link below:
