- size reduction seen in second version was achieved by
- prefiltering the gpx tracks with the en:Ramer–Douglas–Peucker_algorithm implementation used in JOSM (Menu Edit > Simplify way)
- changing gpx2svg.py to reduce the digits of the pixel coords' fractional parts from 13 to 2, up to an upscaling factor of hundred no differences to the original should be seen (i.e. up to a width of 30.000px)
