The picture attached is take from one of the many footbridges in Makati City, Philippines. The two invisible information that can be extracted from the photo are: one, the amount or density of people going to their offices in the city center, and two, the amount of traffic present in the area during 5 o'clock in the afternoon. The amount of traffic, which is an invisible information, helps the city planners in determining or improving the means of circulation throughout the central business district. Without this invisible information, traffic would be congested and the flow of people shall face many problems.
