Using spatial video Google Street View, sub-neighborhood features possibly contributing...
This paper seeks to calibrate an existing analytical framework develop building repair fragility models using a restoration dataset collected through longitudinal field study in the city of Joplin, Missouri, after catastrophic 2011 Enhanced Fujita 5 tornado. First, recovery data set from Joplin is documented and main findings pertaining observed trajectory buildings are highlighted. In next step, various empirical functionality fragilities conditioned on initial level (and associated damage)...
This article establishes a new methodological framework for parallelizing spatial data processing called parallel cartographic modeling, which extends the widely adopted modeling framework. Parallel adds novel component Subdomain, serves as elemental unit of computation. Four operators are also added to express processing, namely scheduler, decomposition, executor, and iteration. A language (PCML) is developed based on framework, designed usability, programmability, scalability. PCML...
There has been a move towards using mixed method approaches in geospatial research to gain context understanding health related social patterns and processes. The central premise is that official data often too reductionist misses' nuances can help explain causality. One example the geonarrative, spatially relevant commentary or interview be mapped by content and/or location. While there have several examples of geonarratives being used researchers, no commonly available software easily...
The importance of including a contextual underpinning to the spatial analysis social data is gaining traction in science community. challenge, though, how capture these rigorous manner that translational. One method has shown promise achieving this aim video geonarrative (SVG), and paper we pose questions advance geonarratives through case study criminal ex-offenders. Eleven ex-offenders provided sketch maps SVGs identifying high-crime areas their Wordmapper software was used map classify...
Abstract Background The utility of being able to spatially analyze health care data in near-real time is a growing need. However, this potential often limited by the level in-house geospatial expertise. One solution form collaborative partnerships between and geoscience sectors. A challenge achieving how share outside host institution’s protection protocols without violating patient confidentiality, while still maintaining locational geographic integrity. Geomasking techniques have been...
Opioid drug overdoses in the United States have continued to rise since 2014. Overdoses are one of several interlinked health challenges faced by marginalized populations. Here we side with argument that these populations can also be a valuable resource address challenges, and use methods elevate this critical belief into real-world application. In article, spatially inspired interviews from both provider participants Los Angeles Skid Row map out microspaces activity. The resulting reveals...
Abstract The 2010 cholera epidemic in Haiti was thought to have ended 2019, and the Prime Minister of declared country cholera-free February 2022. On September 25, 2022, cases were again identified Port-au-Prince. We compared genomic data from 42 clinical Vibrio cholerae strains 2022 with 327 other 1,824 collected worldwide. isolates homogeneous closely related environmental circulating during 2012–2019. Bayesian hypothesis testing indicated that shared their most recent common ancestor an...
The health burden in developing world informal settlements often coincides with a lack of spatial data that could be used to guide intervention strategies. Spatial video (SV) has proven useful tool collect environmental and social at granular scale, though the effort required turn these spatially encoded frames into maps limits sustainability scalability. In this paper we explore use convolution neural networks (CNN) solve problem by automatically identifying disease related risks series SV...
Informal settlements pose a continuing health concern. While spatial methodologies have proven to be valuable tools support interventions, several factors limit their widespread use in these challenging environments. One such technology, video, has been used for fine-scale contextualized mapping. In this paper, we address one of the limitations technique: global positioning system (GPS) coordinate error. More specifically, show how video streams can corrected and synced back original...
Between 1975 and 1979, upwards of two million men, women, children perished from starvation, disease, exhaustion, inadequate medical care, torture, murder, execution during the Cambodian genocide. Within this context, forced evacuation Phnom Penh has figured prominently in literature, especially with regard to violence encountered on route. To date, however, there been no empirical reconstruction evacuation. Here we address deficiency, while simultaneously presenting a novel geospatial...
Abstract Identifying emergent patterns of coronavirus disease 2019 (COVID-19) at the local level presents a geographic challenge. The need is not only to integrate multiple data streams from different sources, scales, and cadences, but also identify meaningful spatial in these data, especially vulnerable settings where even small numbers low rates are important pinpoint for early intervention. This paper identifies gap current analytical approaches near-real time assessment that can be used...
Diffusion of cholera and other diarrheal diseases in an informal settlement is a product multiple behavioral, environmental spatial risk factors. One the most important components interconnections among water points, drainage ditches, toilets intervening environment. This also longitudinal variable as points fluctuate relation to bacterial contamination. In this paper we consider part micro space complexity for three settlements Port au Prince, Haiti. We expand on more typical...
Crime often clusters in space and time. Near-repeat patterns improve understanding of crime communicability their space–time interactions. analysis requires extensive computing resources for the assessment statistical significance A computationally intensive Monte Carlo simulation-based approach is used to evaluate space-time underlying near-repeat events. Currently available software identifying not scalable large datasets. In this paper, we show how parallel spatial programming can help...
Maps have become the de facto primary mode of visualizing COVID-19 pandemic, from identifying local disease and vaccination patterns to understanding global trends. In addition their widespread utilization for public communication, there been a variety advances in spatial methods created localized operational needs. While broader dissemination this more granular work is not commonplace due protections under Health Insurance Portability Accountability Act (HIPAA), its role has foundational...
Inclusion of Location Based Services (LBS) on social media including geo-tagging, and check-ins has been the rise. Users share their location information, motivated by self-expression socialization, as well to improve understanding about places. However, sharing information develops an increased potential for spatial privacy violations. Along with advances in LBS, developments field Geographic Information Systems (GIS) easy use web-maps reverse geocoding services, provide researchers others...
The 2011 Joplin, Missouri, tornado was one of the deadliest and costliest tornadoes in US history, damaging approximately 8,000 structures causing more than $2 billion economic damages. As with most extreme events, reports following documented widespread damage, including complete destruction local hospitals along various schools. However, recovery processes have not been evaluated at same level spatial detail. Following Joplin tornado, researchers periodically revisited neighborhoods...
