Screenshot of identification of missing households. The figure illustrates how by using Google Earth (Earth data: Google, DigitalGlobe) and the GPS data, the progress of data collection can be monitored. The locations of completed household surveys are marked using house icons. The households circled in white are households which were missed. The supervisors were able to direct data collectors by using these maps, to ensure that all households were approached. Source: “Missed households.” 8°08’28.27” N and 80°19’35.42” E. Google Earth.
