OK, I’ve figured out how to get my walks as kml or gpx data.
I can even load them into KDE Marble and see them as a series of positions on a map, with a blue line connecting them. But I can find no offline GNU/Linux tool that will compute the distance, though lots of sugestions that I use Google Earth. (Id like to avoid using google maps data too.)
KDE Marble seems to regard this as point data and not route data, which might be relevant.
Ive never played with GPS mapping so a lot of this is foreign to me.
Im primarily after an easy way to both display routes ive walked and computing distance in a way I can keep a fun historical record for myself.
This is a two mile segment of part of my walk today.
There is some ancient refrences in the KDE Marble wiki to a KDE Workout app which will do exactly what I want; but it doesn’t seem to even exist anymore.
