Google Earth在传染病早期预警结果三维可视化中的应用

摘要

探讨 Google Eanll(GE)在传染病早期预警结果 三维可视化中的应用.模拟实时监测系统,采用前瞻性时空扫描统计量对2005年上海市、江苏省、浙江省214个区县麻疹病例数据进行逐日前瞻性分析.选择其中部分预警结果,采用GE对其进行三维可视化呈现,完整展示预警结果 中包含的时间、地域、实际发病数、理论发病数等若干相关重要信息.GE在传染病实时监测及早期预警中具有潜在的重要应用价值,可进一步研发将其与网络直报系统和聚集性探测方法 集成的计算机系统.%The purpose of this article was to investigate the application of Google Earth (GE)in the Three Dimensional Visualization(TDV)of the warnings signaled by early warning system of infectious disease.As an example.the prospective space-time scan statistics was used by mimicking daily prospective analyses of bacillary dysentery data from Shanghai municipality,Zhejiang province and Jiangsu province in 2005.Then one of the warnings was picked to illustrate the visualization of GE.GE could vividly display the results in three dimensions containing the complex information including date,areas,observed numbers,expected numbers ere.GE seemed a useful tool for infectious disease surveillance and had potential important values in reflecting the emergency response situation.The development of integrated system which consisted of GE,the infectious disease reporting system and cluster detection methods need to be emphasized for further research.
