A case study in Venice mainland. Abstract: This paper deals with the so-called "public city" within North-Eastern Italian context. There are not big modern neighbourhoods, autonomous and self-referential but many small agglomerates, modest public interventions contributed within a pervasively inhabited territory. In particular, the case-study presented is that of Circus neighbourhood in Chirignago (Venice), an exemplar case of social housing in so-called “citta diffuse”. We are not dealing with high forms of segregation, but with molecular forms of exclusion. Nevertheless these contexts are nowadays characterized by many social and physical problems that, through the lens of sustainable cities and economical crisis rhetoric, the research aims to cope with. The paper will present the research first step, an observational survey of Circus collective open spaces and its surroundings, questioning the motives why they are not being used and deserted. Those neighbourhoods have always been considered and handled as places of misery, decay and marginalization and in this perspective the municipality discourses and interventions have always been addressed to. To trigger this condition of isolation the research zooms out, looking at those neighbourhood open spaces at a different scale and position: at the urban landscape scale, looking for a "common space" between private periphery spaces and their prosaic landscape. Identifying all the urban landscape elements that are "public" or reclaimed by inhabitants and associations, with the objective of making images of possible, shared futures to emerge, and putting forward less expensive and "horizontal" strategies to participate in urban transformations.

SLOT 1 (Parallel Session 4) Chair: Mark Graham, University of Oxford (UK) Presentation 1 Author: Cristina Capineri, Università di Siena (Italy) Title: The challenge of big data and citizen science in spatial analysis and geographical thinking Abstract: This contribution aims to address the challenge posed by the growing production and availability of geographic information generated by non-professional users and supported by technologies generally known as Web 2.0. The magnitude of the phenomenon requires attention to the potential applications of geolocalised and georeferenced information that "volunteer geographers," "citizen scientists" or common users produce through Web 2.0. Such new sources of information require first of all a reflection on their influence in geographical theoretical thinking: is geography experiencing a new “positivist” era which include a quantitative soul? or are geographers addressing usual issues with new tools and instruments? Is geography going through a new hybridization with other sciences like computing, statistics and design? The contribution will address the impacts and effects of the production of crowdsourced information in geographical analysis by using a selection of most relevant case-studies and applications recently developed by the geographical community in Europe and in North America and it will focus on emerging theoretical issues, scale, contexts. Topics addressed. Presentation 2 Author(s): Alexander Zipf, Heidelberg University (Germany) Title: The relationship between VGI data quality and usage potential for dynamic geographies Abstract: Volunteered Geographic Information (VGI) evolved to an important source for geo-information and describes the collaborative and voluntary collection of any kind of spatial data. Users participate in VGI communities and share their data with other community members at no charge. As one of the most popular examples of a Volunteered Geographic Information (VGI) project OpenStreetMap (OSM) has more and more become a serious alternative for geodata. Since the quality of OSM data can vary strongly different aspects have been investigated in several scientific studies. In most cases the data is compared with commercial or administrative data sets which, however, are not always accessible due to the lack of availability, contradictory 161
