Map Making Support / Re: Making maps from assembled tracks
« on: March 20, 2012, 02:56:48 PM »
Thank you all for your help.  Just to report back, here's what I did.  One thing I had neglected in my initial requirements is that of the people in my club use smartphones.

I found a pretty good source of data in the form of a JPG, which I calibrated and traced using ExpertGPS (which I had from years ago).   

The problem I ran in to was many of the viewing apps (mostly for smartphones) I used didn't care for tracks that consisted of multiple trksegs, in other words, resulting from tracks that branch or are not contiguous.  Expert GPS also doesn't provide a way to create a single track with multiple disconnected segments.  So, the original problem remained unsolved.

What I did was write a short XSLT (which is a way of transforming an XML file into a different format) to combine all segments with the same name into a single (possibly disconnected track).  That way I end up with a GPX with I think 4 tracks, one for each trail type and for creeks. 

So now, I've got two GPXs, one with simple tracks and another with combined tracks.  GPS units like the combined ones, but I use the simple one for editing and importing into other apps.

Also, for those users with modern Garmin GPS units I used ExpertGPS to export Custom Maps with the trails traced onto aerial photos.

So, in the end, I have files that can be used by old devices (like my eTrex Legend), smart phones, and modern units.  Sorry if it feels like I ignored your advice.  I looked into each of them, and I enjoyed the experimentation. 

After all that, I decided to look into uploading my traces to OSM after they've been validated in the real world.

Map Making Support / Making maps from assembled tracks

Hey all, first of all, thanks for the great resource.  I use a number of the maps made available here, and hope to able to contribute some day.

I've been working on a project to map out the trails in a local park for a club.  I took a bunch of recorded tracks and cleaned them up in ExpertGPS.  I also traced some trails from satellite imagery.  In the end, I have a GPX file with about 60 different tracks.  I thought this would work out, until I loaded this GPX onto my Oregon and discovered I'd have to enable showing each individual track on the map. 

Is there a solution?  Is using tracks for map data like this a bad idea?  I've downloaded a few of the trail map packages here in GPX format, and man, it's a hassle enabling individual tracks.

For what it's worth, I'm the OP from the original, and I wanted to report back that the problem the My Trails map has been resolved for me as well.  Thanks for the help.

Ok, thanks for the response.  It's no big deal, I just wanted to make sure I wasn't doing something wrong.  I have the same problem with the "Illinois Topo" maps, which give two copies on the map list.

Thanks again,

Hello all-

I've been having good luck with the maps here, with one exception.  When I install some certain maps onto the SD card of my Garmin Oregon, I get multiple entries in the list of installed maps (the one you see when you go into Setup > Map > Select Map).

I use BaseCamp, and have a number of maps installed (IL topo, My Trails, NE USA Topo part 1 and 2, etc.).  I renamed all the .img files on my Oregon card to another extension (so I have no extra maps available).  Then I used BaseCamp to install maps.  I selected the "My Trails-High Quality Trail and POI Maps" and selected all segments and installed them.

I've done this multiple times, and each time I get those multiple entries in the list.  Is this a known issue?  Am I doing something wrong?
