Jean-Baptiste Rouquier and Pierre Borgnat, "Cartographie des pratiques du Vélo’v : le regard de physiciens et d’informaticiens"*, Revue Sciences/Lettres [Online], 2 | 2014, 17 http://rsl.revues.org/487 October 2012 (accessed  7 March 2014).From the study of the data of Vélo'v, the Bicycle Sharing System of Lyon and Villeurbanne, several issues are discussed about how researchers from computer science and physics, and not from geography or cartography, were lead to draw maps representing these data. First, the diversity of available digital data is shown, especially for studies related to social or human studies. Some tools to manipulate them are discussed. The example of the Vélo'v data of trips illustrates why and how to propose maps describing features about the movements made with these bikes, or about the availability of bikes or free stands at stations. This practice gives way to a conclusion that suggests a whole new meaning related to the mass of data.Read the full article here (in French).(Translation by Revue Sciences/Lettres.)*"Mapping the use of Vélo'v: a physicist and computer scientist perspective"
