Long Hikes: every track, as GeoJSON

For each trail or route whose record includes a track:

  <id>/<id>.geojson              the main track, full resolution
  <id>/<id>-alternates.geojson   alternate and connector tracks, full resolution, where the
                                 source serves them separately
  <id>/release.txt               the source, licence and date the track files came from

and at the top:

  trails.csv    one row per record, with its licence
  SOURCES.md    each source, its terms, and the trails that use it

Terms. Each track keeps its source's terms and needs its source's credit, as
given in its <id>/release.txt (the Licence and Attribution lines) and in
trails.csv (the licence column). Tracks from OpenStreetMap are
© OpenStreetMap contributors, under the ODbL. The records themselves are
public domain (CC0-1.0).

The GeoJSON files are the full-resolution tracks, as published in this dataset.
The simplified GPX files (5 m) are in all-gpx.zip.
