Aaron Parecki, co-creator of location platformGeoloqi, has collected his location every few secondsfor over three years. He put his data on a map.
How Many Data Points? Approximately one GPS point was recordedevery 2-6 seconds and these imagesrepresent about 2.5 million total GPS points.Collectively, they represent a data portrait ofhis life: everywhere he’s been and the placesI’ve been most frequently. The map iscoloured by year, so you can see how hisfootprint had changed over the years,depending on where he lived.
Methods To get data at this resolution, I had to bring back-up batterieswith me and charge my phone whenever I could. I wouldmanually turn the tracker on when I moved, and turn it off when Iwas at an indoor location for a long period of time. To get thislevel of accuracy results in a great deal of battery drain. One of the reasons why I started Geoloqi is to be able to maketracking this kind of data easier for myself, and to improvebattery life (along the way we took some of my manual methodsfor battery management and bundled it up into a set of mobileSDKs for iPhone and Android for adding location to applicationswithout the intensive battery drain). Below is an image of the script while it is running to produce theGPS maps.
