title: Using geographic information systems to track polio vaccination team performance: pilot project report.
abstract: 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.
