If you upload audio / video / pictures / text with your client, using the pencil
icon on the PDA client , or the "send" button on your Smartphone GPS Tracking client,
the content will be stored and the last picture will always be displayed on the "worldmap"
http://tracker1.reperion.com/wrldMap.aspx?name=dutchnomad (worldmap example)
However, ALL your content is stored and you can create a KMZ file using the KML composer, using
a start date and time, and end date and time. If you open the resulting KMZ (have patience and compassion with our servers)
all the audio pictures and video will be displayed at the position you uploaded it.
The kmlcomposer is here : http://kmlcomposer.reperion.com and the example is here
http://www.reperion.com/example (needs latest version of Google Earth, open the "slider" in the top of the Google Earth screen all the way to the right to see all postions. You can play with this "slider" a bit, click on it, use the properties..etc..

A community for and by the people, the ideas are endless, enjoy !
