Metadata GPS follow-up, Mondulkiri, Cambodia, 2018-2019

We implemented GPS tracking in a rural area of Cambodia, following all participants’ movements for two weeks by providing them a GPS data-logger recording their position. Participants underwent questionnaires about their use of the provided GPS devices. The I-gotU GT600 (Mobile Action Technology Inc., Taipei, Taiwan, Figure 1) was selected to record participants’ mobility. Geographical coordinates were logged every 30 seconds and a smart tracking mode allowed changing interval to 10 seconds when speed exceeded 10 km/h. The GPS data loggers were programmed to be motion activated and hibernate when not in motion to preserve battery life.
