Foretrex 601 design issue.md

• Generating routes on basecamp will generate a GPX file with startPoint and endPoint.

  • The .GPX will also include all the "segments" (where you need to turn, for example) between two points
  • The foretrex will NEVER read those points.
  • The data should either be stripped from the GPX or used by the GPS (second choice is probably better)

• The files where routes/tracks are stored are GPX files (basically XML files)

  • Route line example (len=72 bytes): <gpxx:rpt lat="48.603794574737549" lon="1.569714546203613" />
    • Could be lowered to 16 bytes (2 x double) → 78% size reduction
  • Track line example (len=65 bytes): <trkpt lat="48.587400913238525" lon="1.572611331939697" />
