Geo Waypoints

An exploration of adding waypoint information to Geo data.

Waypoints are geographic points, presented sequentially, describing routes (which may or may not have been traversed at specific times) or boundaries (which may be on any scale, from a small garden to a continent).

The Problem

To allow the publishing of waypoints in such a way that they are downloadable and parsable.

Participants

Real-World Examples

Collections

Typical mandatory attributes

  • Latitude (WSG84, decimal or Degrees-minutes-seconds)
  • Longitude (ditto)
  • text label

Typical optional attributes

  • elevation
  • image
  • note ?
  • url ?

Issues

  • How to differentiate between a route (for example in the shape of a letter "U") and a boundary - in other words, to say whether or not, after the last point, the line returns to the first.
  • How to sequence/ timestamp waypoints
