- Jim,

Not sure whether just downloading to ANY GPS is going to be a test of whether it works on the CO. I have a feeling that all of the extra geocaching stuff that is built into it might be what is breaking its back. GSAK might be "normalizing" it into a well formed GPX with all of the required elements included. As I mentioned in my other post, there is a key element missing in the GPX produced by ExpertGPS, and that is the name of the waypoint. That is what causes MapSource to "renumber" as Mike puts it. I suppose all that was originally intended for the "label" element was that it appear on the map rather than the waypoint name. In ExpertGPS, if you don't provide the name, it defaults to the label. Obviously if you get it from MapSource or GC.com, it is going to have a waypoint name, and the Garmin software was obviously coded upon that assumption. No harm if you use the direct USB connection to the GPS. It supplies the name when called upon which is defaulted to the label value. It sounds like the CO is loaded by copying the GPX file instead of by stream from the USB cable. Otherwise none of this would seem to be that much of a problem. But then, I am making my own assumption here based on the screen shots I saw of the CO geocaching functions.

Anyway, in those nice screen shots of the geocaching stuff, I see what looks like the description that appears on GC.com. Now, that is also part of the GPX schema. That is what you see if you tell GSAK not to go online for the cache description. However, I don't think there is any provision for entering that in ExpertGPS, so it is sorta up for grabs as to what is "standard" GPX. Coincidently, MapSource doesn't allow entry of that kind of stuff either, so it seems logical to assume that although this is a geocaching feature, if the CO accepts a GPX file produced by MapSource, then those element are indeed optional and don't need to be there. So it appears that the only element that is the real show stopper may be the name, and that is fixable without much of a problem at all. Certainly a whole lot less work than manually downloading the GPX for each cache, then merging them together.

 One thing that I tried was to use the "Send To GPS" button on the cache pages, then when I had done it for all 60 caches, I could retrieve them as a GPX file or into GSAK. Of course GSAK receives them as "other" but I switched them to "Traditional" and had a nice export file with the island names I could download to a GPS. Unfortunately, I figured this out at the last minute, and didn't have time to use it for the event, since all the maps were printed. It is something to consider for next year's event.

Nice of you to volunteer. However, the GPX file that expertGPS creates
is not recognized by the Colorado. This is a problem with the Colorado
and not the file. GC.com has their own XML they do and it, along with
Mapsource, are the only GPX files that it works with.

We will need to see if we can get a GPX generated from GC.com on caches
that have not been activated yet.  If we can't, we will hand you the
sheet and you can manually enter them. Either that, or Garmin needs to
correct the GPX load to accept "standard" GPX files from any software
besides their own and GC.com.

The problem we have with using Mapsource is it renumbers all the caches.
I have no idea why, it just does.

Subject: [GeoStL] Updated maps RE: Re: MOGA caches

It was a great time at MOGA!!!!  Thanks to everyone who put it on.


I have updated my maps to include more and better trail data and more

For those without a Garmin and will go latter or will go back, I have a
couple of pdfs that have the caches plotted on the map.  They are much
higher quality than what was given out and they have the trails.  You
can download them on my maps page.  You can also download the source
files with the tracks and waypoints I used to create the maps.

The cache files that were placed on the Colorados not only did not work
right (none of the fancy features worked), they messed things up on the
CO so badly I was not able to download tracks or waypoints.  Nor could
the file on the GPS be opened.  Fortunately, I finally figured out a way
to access the track file and could get the coordinates of the waypoints
on the GPS.
So I was able to use my track files to update the trails.  The problem
is the files were not properly formatted for the CO, so I will volunteer
to make sure they are done right next year.  The problem was the files,
not the CO.

I GPSed the Prairie Loop so it is accurate.  I GPSed part of the Joanna
Trail, RGS GPSed some of it and the rest in the cache area shows up well
on GoogleEarth.  So the Joanna Trail location is accurate.  Not much
shows up on GoogleEarth on the West side so I do not have most of the
mowed paths on the maps.  Lots of stuff shows up on the East side on
GoogleEarth.  I added what I could see to the map, but beware what you
see in googleEarth could be different on the ground.  The traced map for
the Log Cabin Loop is obviously way off.  I took the track RGS gave me
and made a good guess where the trail was since he bushwacked a lot.  So
don't expect that part to be accurate.
But overall the maps should now be pretty accurate.

I talked to Ranger Al who now has a 60CSX with my maps on it.  He said
he is now going to start GPSing stuff.  I am going to help him figure
out how to do it and he will give me the data.  For next year, I will
volunteer to make sure the trails get GPSed and to make sure there is a
good trail map wherever it is.
