Mapping opportunities and criticalities, open geo data as tools to support analysis, public engagement and design.

The thematic chapter illustrates the open-source tools and procedures used in the analysis and mapping of the main environmental variables, with the intention of making information vailable to local actors to support possible procedures for activating the public space. The choice to use open-source tools and data was motivated by the intention to enable communities to implement data and make the environmental survey experience of the UNPark project easily replicable. The mapped data is organized around two macro areas, that of criticalities and that of opportunities. The first includes the retrieval and mapping of information relating to air quality and noise. The second macro area, that of opportunities, presents specific themes starting from the main strategies involved in the development of scenarios oriented to sustainable and circular urban metabolism, namely: use of energy and local resources, reuse, and recycling (Rueda, 2012; Hebel et al., 2014)
