Time geography considers that the motion of moving objects can be expressed using space–time paths. The existing time methods construct space-time paths discrete trajectory points a point object to characterize its patterns. However, these are not suitable for polygon distributed by sets. In this study, we took type crime event as and extracted representative at each moment, median center downscale sets into with timestamps. On basis, were generated connecting adjacent moments extend application scope paths, representing feature from objects. For case City London, constructed path containing 13 nodes (n = 14). Then, edge was considered monthly vector, which analyzed statistically two dimensions direction norm, respectively. results showed events mainly shifted east west, displacement greatest in April. Therefore, proposed study spatiotemporal trends (e.g., events) sets, police achieve improved success implementing targeted prevention measures according characteristics different types.

During the past decades, multiple remote sensing data sources, including nighttime light images, high spatial resolution multispectral satellite unmanned drone and hyperspectral among many others, have provided fresh opportunities to examine dynamics of urban landscapes. In meantime, rapid development telecommunications mobile technology, alongside emergence online search engines social media platforms with geotagging has fundamentally changed how human activities landscape are recorded depicted. The combination these two types sources results in explosive mind-blowing discoveries contemporary studies, especially for purposes sustainable planning development. Urban scholars now equipped abundant theoretical arguments that often result from limited indirect observations less-than-ideal controlled experiments. For first time, can model, simulate, predict changes using real-time produce most realistic results, providing invaluable information planners governments aim a healthy future. This current study reviews development, status, future trajectory studies facilitated by advancement big analytical technologies. review attempts serve as bridge between growing “big data” modern communities.

Abstract Emergent literature suggests that micro- and macro-climates influence criminal behaviour; a complex phenomenon is still incipient in theory development. This mixed-method research starts with systematic review of the on theoretical premises urban heat islands amplify aggressive behaviour crime. Further, it discusses potential implications relationship between environment social outcomes design planning environments. A meta-synthesis was conducted to explain correlations patterns thermal (dis)comfort. correlation relate fundamental principles socially sustainable communities dissuade violence crime, otherwise show poorly designed spaces do propagate behaviour. Cross-validation undertaken using case study Midland, suburb Perth, Western Australia. Data involves population demographics, temperature, crime statistics relating Offences against Person. Analysis focused homicide, assault, threatening behaviour, robbery. The findings imply positive long-term density, green canopy cover. Variables climate (e.g., short-to-long-term climate-related stressors) types also non-linear association. Nonetheless, forecasting future trends through attributes or impacts cover built will inform development policy, environmental planning, strategy, designers, planners. Recommendations are made around these relation making adaptive global warming densification.
