[Cdt-l] Ley maps compass rose coordinates.

[Ken Powers]

Yes, I don't think any of the long distance trails are shown on the Garmin maps. 

I have been working to load traces (tracks) onto my Garmin 60CSx. The problem is still the memory of the GPS units. They just can't hold enough waypoints, trackpoints. etc. One solution with Garmin is to load them as Points of Interest (POIs).  They are like waypoints in a sense, but it is harder to string them into routes. The Colorado Trail folks say you can load the waypoints onto the micro-SD cards they will load automatically when the GPS is booted. I am not sure I ever got that to work. 

My goal is to get traces of shorter segments of trails to load with the waypoints without having to use a computer. I am not there yet.

  Hi Ken,
  This Tarzan PCT '08
  Thank you for this information.  The coordinates will be extremely helpful when loaded into the GPS.  Question, we have the garmin gps and loaded maps and coordinates for our PCT hike, however these garmin maps did not include the PCT Trail itself.  Is this true for the CDT maps also?
  Thanks

    There are lots of programs that will upload the gps coordinates to your gps. EasyGPS and GPSBabel are both free and relatively easy to use. The key is getting a file of gps coordinates that you want to use. You could probably scan Jonathan's if they are on a print file. GPSBabel will move the coordinates from most any recognized filetype (including tpo, kml, gpx, txt and csv) to your GPS or another filetype. If you have a Google Earth KML file just point GPSBabel at the KML and tell it to load the waypoints to your gps. Same thing for Topo's tpo file.

    The next issue is that gps's only hold about 500 to 1000 waypoints. I am putting the waypoint files on 1gb micro-SD cards (about the size of my little finger nail). I may even carry all 3 or 4 through the whole hike. ;)  Each card will hold much more than 1000 waypoints. I'll then load the gps from those cards. I am still working out the best way to do this. I'll get back to you with the final method.

      The coordinates are WGS84.

      There is no file of coordinates on the CD. There used to be, but there were a number of errors in the file, and I had no easy way to keep it updated (there's a line on my web site that needs to be corrected). On average, you'll be going through about 2 maps per day, so that's only 2 gps coordinates you'll need each day - at most... assuming you actually use all of them. Since the coordinates are printed right on the maps, you'll have plenty of time to enter them by hand when you actually need one... Then, you don't have to go searching through a long list to find the right one either.  I wouldn't bother trying to load them beforehand. At first glance, it seems like a reasonable preparatory thing to do, but I don't think it's something you really need to do.

        I believe you're correct WGS 84.  At least thats what I think I used before and it seemed accurate enough.

                  Anyone have a file of the compass rose map coordinates?  It seems like it would be easy enough to do with each labeled according to maps numbers.  Since it would only be 200 something points , it would also be easy enough to load beforehand.
