"gpsbabel -i gpx -f old.gpx -x simplify,error=1m -o gpx -F new.gpx" seems to work nicely to remove redundant midpoints from Maemo Mapper tracks, at least if what I want to do is plot them, e.g. input to merkaartor for OSM. > > ...now I'm reminded I have a "lag" filter patch sitting around somewhere that > does the acceleration points along a straight line thing too, whereas the > filters I've found in gpsbabel only deal with the shape of the track.

For tagging photos I'd want to preserve the time information (and maybe in general, elevation too), i.e. only remove midpoints if they can be reconstructed by linear interpolation.
