Thanks for your response, but perhaps I was not specific enough the first time: I have a track of about 2000 points. Then I have 6 or 7 waypoints that lie along that track. I'd like to be able to quickly know how far along the track those waypoints are. So, if I was to trace the track using the measurement tool, that would take a very long time to do accurately.
On my PC I had a measurement tool...but I just downloaded the garmin software to my Mac and there isn't a measurement tool...where can I find it? :confused::
Why don't you split the track at the waypoints. That way you will have 6 or 7 tracks that gives you the exact distance. You can export the original before you split and import it back into BaseCamp if you want to keep the entire track.
Hi Danhickstein. I found a method to do what you are requesting.I'm not that tech savvy, but I play around with apps. I found TCX converter when I was playing with a GIS software called QGIS
I downloaded a free app called TCX converter. In that app I clicked on "OPEN FILE" and opened the gpx file containing my data.
On the right is a menu and I chose "Save CSV File". When I clicked on "Save", it asked me to choose between ";" (semi-colon)-separated or "," (comma)-separated data.
I opened the saved file in a spreadsheet program such as excel. The distance column actually gives the cumulative distance along the gpx track.
It was then easy for me to calculate distance up to the desired waypoint(s) and used simple addition and subtraction to calculate distance between two waypoints.
