The Art and Cartography working-group of the International Cartographic Association (ICA) was created in 2007 to stimulate the interaction between arts and cartography. Since then, this working group has organized its first symposium in 2008 in Vienna on “Cartography and Art - Art and Cartography”, published an edited book (Cartwright et al. 2009), a special issue of The Cartographic Journal (Caquard et al. 2009)and organized a workshop entitled “Mapping” Environmental Issues in the City: Arts and Cartographic Cross Perspectives, in Montréal, Canada in September 2010. This workshop was designed to encourage and explore the interactions between cartographers, artists, designers and any other area of ‘arts’who work in the various aspects of spatial representation, through the development of original mapping projects inspired by a common ground: a geographic database compiled to study environmental issues in the city of Montréal. This book formalizes the results of this workshop.
