It’s starting to get juicy Bill! I’m pumped to try this feature

Bill,

This is a great feature, but I'm running into an issue. I may have the answer, but wonder if you can confirm (sorry if this has already been explained):

It appears that when there are no downloadable GPX files, the site just returns all downloadable GPX files. That is, I see no number in parentheses after, for instance, Eagle Peak A in the drop-down, and it returns 1419 GPX files - none of which seem to be for Eagle Peak A (see screenshot). And if I search trip reports for Eagle Peak A, I see Otina's has a GPX file, but it is not downloadable. (If I do the same trip report search but restrict to ones with a GPX file, it returns zero.)

I do sometimes like to see others' GPX routes, but I don't expect to ever download one (to take on a hike, for instance). I know it's nitpicky since it's not much more work to comb through results via the trip reports menu, but do you have plans to populate the GPX menu with non-downloadable files, too?

Either way, thanks for the continual upgrades to the site.

^^ I noticed this too, as apparently I only have 3 gpx files that I’ve allowed downloads for (2 are likely mistakes). I was also wondering if you were going to add these gpx tracks to the mix (yet keep them map only, no download), since I have zero problem with users viewing the tracks - I just don’t want someone blindly following my tracks, since sometimes I didn’t always choose the best route, and people should read the TR to find out my decision making thoughts. I also think people should use their brains, and not follow the pings in a gps unit.

I could have sworn I completely read your Boulder Mountain-Mount Mamma report before taking the same route. I re-read the report when I got back and somehow clearly missed the swinging from aspen to aspen on the descent. Holy crap that was a steep mess. So yes, folks really need to read reports (twice!) before following a route.

Yes, precisely why I don't like following the tracks on a GPS. I often like to get a sense of the possibilities and then figure it out on the ground for myself.

Thanks for pointing out the problem when a peak is selected that should have no results. Ben also mentioned this to me but I forgot to fix it. It should work now.

As far as trip report GPX files, they only get included in the GPX Library when downloading has been allowed by the report author. I'll think about the "non-downloadable" option in the GPX Library so we can get more in the library but stick with the wishes of the trip authors. This may make things a bit confusing since people would probably only visit the library when they're looking for a GPX file for download. Let me think about that.

bergsteigen, if you do end up changing those few of your TRs to remove the public sharing option, just be aware that right now the GPX Library only sweeps trip reports once a day so it will take a day for a file to fall out of the GPX library.

Thanks, Bill. Like I said, it's nitpicky, and I'll obviously live with it either way. Checking out the GPX files is just one step in the research process, so I'd probably end up finding them when looking up TRs anyway.

NERD ALERT!!!

As I mentioned previously, when viewing a GPX file in the library, an elevation profile can be generated by clicking on a track line. Currently, the profiles use Google elevation data obtained though their lookup service. Google only allows us to retrieve ~500 elevations along any track line so, for long tracks, I've found this is not good enough since it reduces the distance calculations as the tracks get longer. So, I've decided to host a 30 meter, 1-Arc Second elevation lookup system using the space Shuttle Radar Topography Mission (SRTM) data, obtained by Endeavour in 2000. This will provide elevations accurate to 30 meters and as many as we want per track.

Once I get all of the data files on the site and finish the programs to retrieve elevation data, I'll convert the current profile process so track profiles are more accurate.

I need to seriously up my nerd game, this is like hieroglyphics. And I had to google just to spell hieroglyphics.

I've finished adding the elevation lookup service so we don't have to rely on Google for the information. Route profiles in the GPX Library, route descriptions and elsewhere now use the new process.
Free and faster.
