![]() Therefore, knowledge of human spatial behavior is paramount for the development of effective disease surveillance and prevention programs.ĭespite its epidemiological relevance, our understanding of the relationship between human movement and pathogen transmission remains limited, in part due both to the lack of precise and cost-effective tools to quantify human spatial behavior and the challenges of data processing. Whereas migration is generally associated with the long-distance spread of disease and the (re)introduction of pathogens into a particular area, circulation of humans within their activity spaces can be important in the local spread of pathogens and, ultimately, on the fate of disease outbreaks. According to its dynamic and complex spatiotemporal nature, human movement can be broadly classified as migratory (i.e., permanent change of residence) or circulatory (i.e., short-term, periodic movements associated with work or leisure). Human movement plays a significant role in the transmission of pathogens, spread of infectious diseases and drug resistance, and emergence of novel pathogens. Cost, battery life, size, programmability and ease of wear are unprecedented from previously tested units, proving the usefulness of GPS-dataloggers for linking movement of individuals and transmission risk of dengue virus and other infectious agents, particularly in resource-poor settings. The present study demonstrates the feasibility of a novel, commercially available GPS data-logger for long-term tracking of humans and shows the potential of these units to quantify mobility patterns in relationship with dengue virus transmission risk in a tropical urban environment. Most (80%) of the locations identified by participants alone were places reported as visited for less than 30 minutes. GPS and participants' interviews concordantly identified 6 common locations, whereas GPS alone identified 4 locations and participants alone identified 10 locations. The carpenter moved less and spent more time in more fixed locations than the moto-taxi driver, who visited more locations for a shorter period of time. The application of a clustering algorithm (I-cluster) to the raw GPS positional data allowed the identification of locations visited by each participant together with the frequency and duration of each visit. Units were worn on a neck-strap by a carpenter and a moto-taxi driver for 14-16 days. GPS wearing mode increased spatial point error by 6.9 m. Positional point and line accuracy were 4.4 and 10.3 m, respectively. GPS observations from two participants were later compared with semi-structured interview data to assess the usefulness of GPS technology to track individual mobility patterns. We conducted a series of evaluations focused on GPS device attributes key to reliable use and accuracy. We determined the utility of a new, commercially available, GPS data-logger for long-term tracking of human movements in Iquitos, Peru. ![]() Trackmaster works great for autocross, hill climbs, road rally, and track days.Our understanding of the effects of human movement on dengue virus spread remains limited in part due to the lack of precise tools to monitor the time-dependent location of individuals. Lastly, the app allows you to overlay your laps to compare your race line. Launch Street View to see a panoramic view of your race line and the track. You can also automatically upload your video to , view your lap times and split times with graphical analysis on your phone.What's really neat is that you can send your data to Google Earth for desktop replay, analysis, and editing.Įnable speech on Trackmaster in order to have your speed and times spoken to you while you're racing, which can be done via a Bluetooth head set. Use Live View to provide real-time track data and position to your fans or race with your friends using the Race Group feature. You can start this recording using any number of triggers such as immediate, by movement, delayed, or by first split marker. You can record a bunch of track data: position, speed, acceleration, altitude, bearing, absolute time, split times, elapsed times, and lap times. Like most things Android, there is a lot of customization bundled into this app. Because not all motorcyclists have iPhones, there's Trackmaster available for Android.
