The present project is a collaborative environment that stimulates the production and exchange of perceptions about urban space and its use. For this, notions of alternative, participative and online cartography were combined with concepts of co-creation and sharing present in networks and social media. It started from the reflection about the urban space and its layers of meaning, observing the subjectivity of the city and its everyday life that stimulated the will to value what is considered ordinary and common. Its development was based on prototypes and tests with potential users.
