[Geowanking] GPX Tracklog Viewer

[Just van den Broecke]

Hi Jim,

This is really great stuff! I can see possibilities for displaying 
additional (geolocated) info (e.g. POIs, media) based on a general 
observer/listener pattern. So for example, in GeoSkating 
(www.geoskating.com) I have media related to locations. By registering a 
"callback" for a list of locations (each with opaque user data 
e.g.object id's) while the trail is moving on each callback I could 
display media related to the position. Registration options could be to 
halt the player during callback, and to be resumed by observer. A sort 
of local LBS. It could also be simpler, just callbacks with locations to 
listeners who can then decide what to do (displaying media, time, 
elevation, POIs whatever).

Other: a "player-controller" (start, stop, pause, faster/slower etc).

I think also live tracking could be easily realized using this 
technology. For example I currently use Pushlets (www.pushlets.com, 
Javascript Server push) for this matter.

Would like to learn how you programmed this (peeking into 
http://jibbering.com/mapping right now...) and if you always need  GMaps.

best,

--Just
