The application of geospatial data to public health problems has expanded significantly with increased access to low-cost handheld global positioning system (GPS) receivers and free programs for geographic information systems analysis. In January 2010, we piloted the application of geospatial analysis to polio supplementary immunization activities (SIAs) in northern Nigeria. SIA teams carried GPS receivers to compare hand-drawn catchment area route maps with GPS tracks of actual vaccination teams. Team tracks overlaid on satellite imagery revealed that teams commonly missed swaths of contiguous households and indicated that geospatial data can improve microplanning and provide nearly real-time monitoring of team performance.
随着低成本手持全球定位系统（GPS）接收器和免费地理信息系统分析程序的普及，地理空间数据在公共卫生问题中的应用得到了显著扩展。2010 年 1 月，我们在尼日利亚北部试点应用地理空间分析方法辅助脊髓灰质炎补充免疫活动（SIA）。SIA 团队使用 GPS 接收器将手工绘制的集水区路线图与实际接种团队的 GPS 轨迹进行比较。团队轨迹叠加在卫星图像上，显示出团队通常会错过连续的住户区域，并表明地理空间数据可以改进微观规划，并提供团队绩效的近乎实时监测。
