This tool lets you create multiple features based on an attribute, so you could give all the points a common value in the attribute table and make multiple polyline features (for example: car route to trailhead, main hike route, side trip). Use the Points2One plugin to convert the points into a polyline feature. It is much easier to edit individual points than nodes within a single, large feature (what you get if you open the Track instead Track Points of the GPX). Turn on editing for this new file and remove all the junk points (at the beginning and end of the trip, for example). You'll have to save this as a shapefile to edit it (see the video in the link above). Each point will retain its timestamp and elevation in the attribute table. You'll get five options for what type of data to import: choose "Track Points". To open your GPX track, go to Add Vector Layer (in the menubar: Layer > Add Layer) and browse to your GPX file. This solution is a little simpler than the others, can be done with just two QGIS tools, and there is no need to manually edit the GPX file. I found a simple way to clean up GPS tracks: 1) load the points from the track in the GPX file ( Add Vector Layer) and 2) join the points into polylines with the Points2One plugin.

OSM based basemaps) so there's no need to spend time setting up special mapping for this when you already have your GIS software set up for ordinary GIS work. So you are left with the original file unscathed I think.Īs a bonus it also works well 'out of the box' with various basemaps (e.g. It may be useful to note that it opens GPX files by importing them - and saves by exporting. And it'll work with photo geotagging/geotags too - so if you work with a smartphone or gps enabled camera it's simple to see everything in one place. allow for joining and splitting of tracks, recognises track segments ('trkseg') and can work with these, and so on.
And it will show up the times and other data from the track waypoints. So if you work with a comment on a track it appears in the proper 'cmt' tags in the file for example. So I don't see it (so far) messing around with adding silly extension tags to the file - instead working within the normal GPX specification. A cool feature of this software is not just the fact that it supports different GPS hardware, but it can also convert between different applications such as Basecamp and Google Earth. It works quite like GIS software with its ideas of layers and a basemap - but what's particularly pleasing is that it appears to work well with the GPX file structure/specification (rather than working in spite of it). GPSBabel is a program which can convert waypoints and routes between various brands of GPS receivers including Garmin and Magellan. I'm new to it and I'm testing it but so far I'm really pleased. Viking GPS editor seems to do a good job. Having previously answered this question (with the suggestion to use JOSM and a text editor) I think I now found a better answer.
