\section{Data Visualization}

Collection of data is done in a collaborative way, this means that there are several users running the logging application which periodically sends an update to the server with new data. 

\input{pictures/heatmap_progress}

To make it easier for users to see which areas that has been visited before, a heatmap (figure \ref{heatmap_progress}) of all the logged data points were constructed, this heatmap is also meant as an incentive since the user can actually see the progress. The code for setting up the site can be found at my github repo \cite{HeatmapGitRepo}.
