Almost everyone has a smartphone these days. All these phones have a GPS and that can be used to record a track you walk, run or bicycle. In this thesis we used that data recorded by an external application and imported it into our application. The project has three parts. We need to store the data somewhere first before using it. So the first part is designing a database. The resulting database is a compact database that can run on a smartphone. After storing the data, we can use it. In the second part we analyse the data. This is called time series analysis. Time series analysis is done by linear regression, Gaussian processes (kriging) and a combination of both. The final part of the thesis is about visualising the created regression model and other statistics generated from the imported data.
