Swedish emergency services still have relatively limited resources and time for proactive fire prevention. As a result of this, there is an extensive need for strategic working methods and knowledge to take advantage of spatial analyses. In addition, decision-making based on visualizations and analyses of their own collected data has the potential to increase the validity of strategic decisions. The objective of this paper is to critically examine how some different geovisualization techniques—point data, kernel density and choropleth mapping—actively can complement each other and be applied in fire preventive work. The results show that each technique itself has limitations, but that, in combination, they increase the scope for interpretation and the possibilities of targeting different forms of preventive measures. The investigated geovisualization techniques facilitate various forms of fire prevention such as identifying which areas to prioritize for outreach, home visits, identification and targeting of different risk groups and customized information campaigns about certain types of fires in risk-prone areas. Furthermore, fairly simple mapping techniques can be utilized directly to evaluate incident reports and increase the quality of geocoded fire incidents. The study also shows how some of these techniques can be applied when analyzing residential fire incidents and their relation to underlying structural and socio-economic factors as well as spatio-temporal dimensions of fire incident data. The spatial analyses and supporting maps can help find and predict risk areas for residential fires or be used directly to formulate hypotheses on fire patterns. The generic functionality of the visualization methods makes them also useful for visual analysis of other types of incidents, such as reported crimes and accidents. Finally, the results are applicable to a work process adapted to the Swedish legislation on confidential data.

防火的地理可视化和地理分析

瑞典的紧急服务部门在主动预防火灾方面的资源和时间仍然相对有限。结果，迫切需要利用空间分析的战略性工作方法和知识。此外，基于可视化和对自己收集的数据进行分析的决策有可能提高战略决策的有效性。本文的目的是批判性地研究一些不同的地理可视化技术（点数据，核密度和孔隙度映射）如何主动地相互补充，并应用于防火工作中。结果表明，每种技术本身都有局限性，但结合起来，它们增加了解释的范围，并增加了针对不同形式的预防措施的可能性。所研究的地理可视化技术可促进各种形式的防火，例如确定哪些区域应优先进行外展，上门拜访，识别和确定不同风险组的目标以及针对易发风险区域中某些类型火灾的定制宣传运动。此外，相当简单的制图技术可以直接用于评估事故报告并提高地理编码火灾事故的质量。这项研究还表明，在分析住宅火灾事故及其与潜在的结构和社会经济因素以及火灾事故数据的时空维度的关系时，如何应用其中的某些技术。空间分析和辅助图可以帮助发现和预测住宅火灾的风险区域，或直接用于制定火灾模式的假设。可视化方法的通用功能使它们也可用于可视化分析其他类型的事件，例如报告的犯罪和事故。最后，结果适用于适应瑞典关于机密数据的立法的工作流程。
