Geo Waypoint Trails
An exploration of publishing trail or boundary information using series of Geo data waypoints.
Waypoints are geographic points, as currently published using the geo microformat.
Presented sequentially, they can describe trails or 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 series of waypoints in such a way that they are downloadable and that their ordering is parsable.
Participants
Real-World Examples
- Jiri to Everest Trek in Nepal
- (or any other treks on that site)
- relevant mark-up:
<tr><td>Jiri Bus Park</td><td>27° 38.173'</td><td>86° 13.909'</td><td>1924</td></tr>("1924" is the elevation)
- http://members.aol.com/gpspage/waypoints.html
- Freshman Seminar Waypoint Hunt
- relevant mark-up:
<tr><td>BENCH</td><td>40.33855</td><td>-74.66465</td><td><a href="bench.html"><img src="bench_c.gif" alt="[...]"></a></td></tr>
- relevant mark-up:
Collections
- POI66
- example: Amsterdam CS-Alkmaar CS walking route (n.b long page; 612 waypoints)
- relevant mark-up:
<li><div>waypoint 10<br/>Latitude 52.386165<br/>Longitude 4.91199</div></li>
Other
- GPX - XML schema for trails
Typical mandatory attributes
- Latitude (WSG84, using decimal or degrees-minutes-seconds values)
- Longitude (ditto)
- text label
Typical optional attributes
- elevation
- image
- note ?
- url ?
Issues
- How to differentiate between a trail (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
