“…(3) Finally, KDE and a spatial filter were applied to search for clusters in the point data. Although kernel density may be a more popular approach for identifying clusters in point data, it lacks statistical rigor, which a spatial filter technique provides (Curtis et al, 2010).…”

How people feel about places matters, especially in their neighborhood. It matters for their health, the health of their children, and their social cohesion and use of local resources. A growing body of research in public health, planning, psychology, and sociology bears out this point. Recently, a new methodological tack has been taken to find out how people feel about places. The sketch map, a once popular tool of behavioral geographers and environmental psychologists to understand how people perceive the structural aspects of places, is now being used in concert with geographic information systems (GIS) to capture and spatially analyze the emotional side of urban environmental perception. This confluence is generating exciting prospects for what we can learn about the characteristics of the urban environment that elicit emotion. However, due to the uncritical way this approach has been employed to date, excitement about the prospects must be tempered by the acknowledgement of its potential problems. In this paper we review the extant research on integrating sketch maps with GIS and then employ a case study of mapping youth fear in Los Angeles gang neighborhoods to demonstrate these prospects and the problems, particularly in the areas of (1) representation of environmental perception in GIS and (2) spatial analysis of these data.

“…One of the few published examples of its use as a research tool has been to monitor differences in rates of recovery and continued abandonment between New Orleans neighborhoods post Hurricane Katrina. 15 To our knowledge, however, Google Street View has not been used to undertake streetscape audits for research purposes. Thus, the potential use of Google Street View to audit these settings has important methodological implications for the built environment research field in terms of possibly increasing the efficiency of environmental measurement.…”

Can Virtual Streetscape Audits Reliably Replace Physical Streetscape Audits?

et al. 2010

There is increasing recognition that the neighborhood-built environment influences health outcomes, such as physical activity behaviors, and technological advancements now provide opportunities to examine the neighborhood streetscape remotely. Accordingly, the aims of this methodological study are to: (1) compare the efficiencies of physically and virtually conducting a streetscape audit within the neighborhood context, and (2) assess the level of agreement between the physical (criterion) and virtual (test) audits. Built environment attributes associated with walking and cycling were audited using the New Zealand Systematic Pedestrian and Cycling Environment Scan (NZ-SPACES) in 48 street segments drawn from four neighborhoods in Auckland, New Zealand. Audits were conducted physically (on-site) and remotely (using Google Street View) in January and February 2010. Time taken to complete the audits, travel mileage, and Internet bandwidth used were also measured. It was quicker to conduct the virtual audits when compared with the physical audits (χ=115.3 min (virtual), χ=148.5 min (physical)). In the majority of cases, the physical and virtual audits were within the acceptable levels of agreement (ICC≥0.70) for the variables being assessed. The methodological implication of this study is that Google Street View is a potentially valuable data source for measuring the contextual features of neighborhood streets that likely impact on health outcomes. Overall, Google Street View provided a resource-efficient and reliable alternative to physically auditing the attributes of neighborhood streetscapes associated with walking and cycling. Supplementary data derived from other sources (e.g., Geographical Information Systems) could be used to assess the less reliable streetscape variables.

“…Badland et al (2010) find GSV audits to be faster and less expensive than physical site visits and that efficiency improves rapidly with user experience. Curtis, Duval-Diop and Novak (2010) use GSV to audit New Orleans to identify neighborhood patterns of return and rebuilding after Hurricane Katrina. Although video was available from local community groups, the authors find that GSV is just as effective and chose to rely on GSV as their data source so that their methods could easily be replicated.…”

This article describes a Los Angeles-based website that collects volunteered geographic information (VGI) on outdoor advertising using the Google Street View interface. The Billboard Map website was designed to help the city regulate signage. The Los Angeles landscape is thick with advertising, and the city efforts to count total of signs has been stymied by litigation and political pressure. Because outdoor advertising is designed to be seen, the community collectively knows how many and where signs exist. As such, outdoor advertising is a perfect subject for VGI. This paper analyzes the Los Angeles community's entries in the Billboard Map website both quantitatively and qualitatively. I find that members of the public are well able to map outdoor advertisements, successfully employing the Google Street View interface to pinpoint sign locations. However, the community proved unaware of the regulatory distinctions between types of signs, mapping many more signs than those the city technically designates as billboards. Though these findings might suggest spatial data quality issues in the use of VGI for municipal record-keeping, I argue that the Billboard Map teaches an important lesson about how the public's conceptualization of the urban landscape differs from that envisioned by city planners. In particular, I argue that community members see the landscape of advertising holistically, while city agents treat the landscape as a collection of individual categories. This is important because, while Los Angeles recently banned new off-site signs, it continues to approve similar signs under new planning categories, with more in the works.
