The project core idea is to give the ability to users to collaboratively annotating a two dimensional representation of the city. The users can see a map of the city on the screen of their mobile. They can see their position plus the position of their peers. Using some editing tools offered by the platform, they can add small text (or pictures or video) to their position for other user to retrieve.
Consequently to this layering of information, a social representation of the city is constructed. The aim of the project is to give people the ability to represent their ideas of the space, communicating using this space and then navigating the space using marks that other users have left into the system.
