Thanks for the script! It's useful to me as well because my Garmin bike navigator starts to throw trackpoints away after a certain number of trackpoints is reached. Choose a name and location for the output file. Select Filter to bring up the filter menu. In the Data Filters menu, select Miscellaneous> Transform > Tracks to Routes > OK. This should work for example with the GPX tracks generated by # by transforming UNICSV waypoints back to trackpoints # convert separated UNICSV files back to GPX track files I added a separation of waypoints and tracks and a little bit of "compression" to Harald's script (which works in zsh as well). If you dont need the time information, you can add a fake time, and then splitt according to the added time. The example takes an unknown track, reduces it to 2000 points, adds a timestamp beginning at the and then makes four tracks with 500 waypoints each. So by getting the first 500 waypoints, get the range up to including 8min 19sec. Pitfall in this example: If there is more than one track in the source, simpify seems to work on each track individually, so there might be more than 2000 waypoints in the output. In this case, there will be waypoints missing at the end. Gpsbabel -t -i gpx -f MultiDayTrackToGo.gpx -x simplify,count=2000 -x track,faketime=f20000101000000+1 -x track,start=20000101000820,stop=20000101001639 -o gpx -F part2.gpx p Preferences file (gpsbabel.ini) -s Synthesize shortnames -r Process route information -t Process track information -T Process realtime tracking information -w Process waypoint information default -b Process command file (batch mode) -N No smart icons on output -x filtername Invoke filter (placed between inputs and output) -D level Set. Next, the split tracklets are sent into Connector to learn representative embeddings. gpsbabel -t -i gpx -f in.gpx -x track,pack,split,title'ACTIVE LOG D' -o gpx -F out.gpx. Finally, the tracklets with the similar embeddings are grouped to form clusters, i.e., to generate the final entire track. The framework of the tracklet booster is shown in Figure 2. The details of Splitter and Connector are demonstrated in the following sub. Additionally you can add an interval to the split option. With this the track will be split if the time between two points is greater than this parameter. The interval must be numeric and can be int days, hours, minutes or seconds, expressed as one of.

One thing I have found is that the free program EasyGPS will always open gpx files, even the ones that Mapsource barfs on.
After you simply open and save the gpx file with EasyGPS, then Mapsource will open it. I've never seen it fail.ĮasyGPS does not handle maps. (There are other licensed Topographix products that do.) It only handles uploading and downloading of files with your GPS receiver, and some basic file manipulations. It is really quite good for carrying and sharing files. Using my file as an example, it has sample data in it (also shown in the image below), Katherine paid for the train tickets, the tickets cost 1000, and the tickets were for Joe, Beth, Rob, and Katherine, so each owes 25 of the total cost.

You just keep all your files and a copy of EasyGPS on a flash memory chip and you can plug it into any PC, plug in just about any GPS receiver and you can up and download files. This design allows for some flexibility in how the costs are split. I didn't see any mention of the filter function available in Mapsource. If you open your file in Mapsource and double click on the track name you get the Track Properties window. It will give you several options for reducing the number of trackpoints. It will give you a track of 500 or less points which works just fine for most purposes. The other option, as mentioned is to use the Cut tool found in newer versions of Mapsource and break it down into multiple tracks. You would only need this if you need all of the original detail of the route.
