Thanks for the help guys, I did manage to get this to work in the end.
I've done some simple perspective renderings of the London
trackpoint data, but this list won't let me attach images.<br>
<br>
The track points don't always seem to be in time order - i.e. if
you draw lines between them you often get a big mess. Why is this?<br>
<br>
It's not map related, but here's a link to some of my visualization work:<br>

It was working for me with either 0.1 or 0.2 this last week. For an example<br>try the following box for track points:<br><br><a href="http://www.openstreetmap.org/api/0.2/trackpoints?bbox=52.15,-2.5,52.82,-1&pa">http://www.openstreetmap.org/api/0.2/trackpoints?bbox=52.15,-2.5,52.82,-1&pa
</a><br>ge=n<br><br>where n is the page number starting with zero. Each page returns 5000<br>points. The newest points are provided in the first pages and the oldest on<br>the later pages. No way to know how many pages at present. And yes, from
<br>what I can tell they are in time order albeit that no time stamp is provided<br>with the data returned.<br><br>Similar for nodes and line segments but with "map" rather than "trackpoints"<br>and no page requirement.
<br><br>This boundary box covers the west midlands, which is steadily building a<br>good coverage of GPS and map data.<br><br>Andy Robinson<br><br>-----Original Message-----<br>From: <a href="mailto:openstreetmap-bounces@vr.ucl.ac.uk">
