Here is a map of freely available flowers in Toulouse:

Using google map, it’s possible to add this pins (markers) on the map, and it’s possible to add lines between these markers, so everything is there to implement basic functionnalities.

Once the basics are done, the next steps could be more interesting: how wirtual maps can extend the experience?

• Add a slider to navigate thought time, David’s idea with his students about extending google maps with history layers (see google market sliders);
• Have the possibility to add future markers, so your friends - or other people - can see your plans for coming weeks. Serious privacy issues, but all the tracklog concept lay on these issues;
• Creating a multi-layer map with friends or other people on it, there we are really near a Global Surveillance concept;
• Color change on path, depending on the transport - plane, foot, bicycle, … - or relate to the time slider with a nice gradient.
