<p>Regenerates the surface tracks as survex files from GPS .gpx files. Also requires the gpx2survex program.
<p>We use the OCAML program gpx2survex but we now also have a python equivalent gpx2survex.py which is used by make_svx2.sh This is part of the make_essentials generation process.
<p>gpx2survex simplifies a track so that it is less voluminous.
<p>For the reverse process we don't need a script. For svx-to-gps we can use <var>survexport</var>: Olly says [2022]: "you shouldn't need to mess around with undocumented scripts - since 2018, you can just do:
<var>survexport --entrances all.3d essentials.gpx</var>"
<p>But that does rather rely on <var>all.3d</var> being properly generated, which troggle does not currently do reliably and automatically.
