-On this picture, we can see industrial warehouses on the foreground, appartement building on the right, and a train station in the background. -The first type of invisible information could be the fluxes of people transfering from the trains to other means of transportation (here there is a metro station, a tram station and multiple bus stops.) Another type of information could be the living places of people working in those warehouses, and the working places of people living in those appartements. -The first type of information could be used to decide how to correlate the different means of transportation's schedules, and what lines to reinforce for example.
