From: Complete trajectory reconstruction from sparse mobile phone data
Example of the observed trajectory of a user. The trajectory is recored during \(\mathcal{T}=15\) days and has a degree of completeness in 0.27. Each grid element maps to the representative location associated to each time interval of \(\tau =1\) hour. Colors map to different places: the most active daytime and nighttime locations are marked in pink and blue respectively; white blocks are missing locations. Figure best viewed in colors
