“…Their work leveraged a suite of open-source spatial infrastructure, land-cover, and development data from sources such as OpenStreetMap (OSM) 19 and Google Places; 20 however, there is no guarantee of completeness for these and other types of open data sources, and the accuracy of their social capital measurements relied heavily on the integrity of their input datasets. In other work, 18 we quantified the relative completeness of various infrastructure types in OSM and Google Places datasets for Los Angeles, CA, demonstrating incompleteness in both datasets and a nonuniformity in the level of completeness across the region.…”

“…Most studies rely on intensive in situ research methods that, by necessity, focus on one or two small neighborhoods; however, by combining computational tools and social science concepts, researchers have been able to implement a novel approach to assess the resiliency of an entire DUT. [16][17][18] Palladino et al 16 used an urban resilience ontology that related social structures and social events including access and capacity to compute a social capital measure for the entirety of a DUT landscape.

As humans increasingly settle in dense urban areas, localized natural and anthropogenic shocks become more likely to impact larger numbers of individuals. Research suggests that resilience to shocks is a function of physical fortifications and social processes including critical infrastructure, social networks, and trust. Although physical fortifications are relatively easy to identify and catalog, social processes elude simple measurement due to data limitations and geographic constraints. Recent work has shown that certain types of infrastructure may correlate with social processes that enhance community resilience; however, the ability to assess where and to what extent that infrastructure exists depends on a complete representation of the built environment. OpenStreetMap (OSM) and Google Places are two sources of data commonly used to locate and characterize infrastructure, but they are often incomplete. We address this limitation by applying a convolutional neural network (CNN) to remote sensing data from Sentinel-2 to estimate the density and type of infrastructure. We compare the classification results to known infrastructure locations from OSM data. Our results show that the CNN classifier performs well and may be used to augment incomplete datasets for a deeper understanding of the prevalence of infrastructure associated with social processes that enhance community resilience.

“…As has been established, recent research [6] argues that although areas with better access to social infrastructure should support higher social capital, this may still be a theoretical argument that has not been tested properly by quantitative frameworks. This represents one of the main motivations of the work presented here: to suggest a framework for the study of some of these concepts, through the construction of robust indices that may help shed some light on these urban phenomena.…”

Vulnerable Neighbourhoods, Disaffiliated Populations? A Comprehensive Index of Social Capital and Social Infrastructure in Barcelona

This article aims to understand the probable links between social capital and social infrastructure. The inclusion of these two dimensions into urban analysis may help to better understand the nature and characteristics of the relationships between the built environment and the level of organisation of the residents, and whether these have an impact on the vulnerability of the territories. Through use of statistical techniques (visual grouping and cluster analysis, among others), this article seeks to construct a comprehensive measure of social capital, as well as a comprehensive index of social infrastructure. These two in combination show, as the main results, that the characteristics of the built environment may promote higher levels of social interaction, also leading to higher levels of civic engagement and participation. However, the results also suggest that this relationship may be bidirectional. Finally, the mapping of the two indices applied in the city of Barcelona is presented and these results are compared with a previously constructed index of vulnerability for the same territory, allowing an overall better understanding of Barcelona’s socio-urban behaviour.
