Geo Waypoints

An exploration of adding waypoint information to Geo data. Waypoints are a series of points, describing routes or boundaries.

The Problem

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

Participants

• Andy Mabbett

Real-World Examples

• Jiri to Everest Trek in Nepal
  • (or any other treks on that site)
• http://members.aol.com/gpspage/waypoints.html
• Freshman Seminar Waypoint Hunt

Typical mandatory attributes

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

Typical optional attributes

• elevation
• image
• note

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
  • Perhaps using hAtom and/ or hCalendar?
