I have just uploaded another small test suite for enabling geo-tracking on the web. This is similar to the Carnegie Great Student Run demo, but I plan to have it individualised for several people so that each can update their location - and show it on a web page. In the image below you can see my current location as it is in the database (earlier problems re. updating have been solved now). This is a "live" IFRAME showing Google Maps; as I keep updating the position and the software, the image actually will change.
Since my first entry of this blog entry I have dobe a few modifications: the refresh is automatically triggered, depending on the time the user last had updated the location. Over time, the icon fades slowly away when no location updates are received. The icon color depends on the category of the user - this is to prepare for future collaborative work. The icon blinks when the updates are from GPS within the last 5 minutes.
A smaller version of this map is included in this blog here in the left column under "My Location".
Stay tuned for more news!

2nd event: "Mini Marathon"
Right now the second of today's run events is on: a 1.25 km "Mini Marathon".
They are running right now, should be finished any time.
The tracking experiment went very well.
Paul Hartshorne, Simon Crossley, and Sean McCabe were tracked by their mobile phones. Sean's phone/GPS seemed to provide only rarely updates, but the two other devices sent their locations in regularly, so one could watch as the icons moved across the run.
I realised that I might have made a mistake in plotting the run course: the runners were sometimes a bit off and run where there was no track marked on the screen. I had taken the course from the official Great Run website, but that might have been an older version (or I might have left off a few corner points).
In the course of the testing I also uncovered a small problem re. the icond redraw - which is now solved. Now I can add a bit of functionality. Great would be to record the whole track... is no problem, but I had not implemented this as I did not want to run out og memory and storage space during the run.
Overall, it was a great success, I think!
