Crowdfunding and Crowdsourcing: New Challenges for the Visual Documentation of City Cultures

The aim of the article is to present the challenges posed to the visual documentation of city cultures by the new social phenomena of crowdsourcing and crowdfunding, which create new forms of participation in shaping urban culture and the urban community. In order to discuss the new phenomena some examples will be shown. A fake subway map, a crowdmap or an amateur science project data visualization show how visual tools can be used in the crowdsourcing and crowdfunding models of action as a collaborative project.
