At the busy 'Crazy Signal' in Doha, Qatar, one can clearly identify the various visible data sources (indicated in black in the image) including, but not limited to, Traffic Patterns, Building Heights, Residential and Daytime population, Locations of various civic amenities such as the Civil Defense Station and the Capital Police Station and also locations for signage and advertisements. The invisible information (indicated in white) that can be gathered from the visible information includes - Employment densities which can in turn be used to identify employment centers within the city and thereby assist in the planning of Business districts and its associated infrastructure. - Traffic Patterns can be used to determine average waiting times at intersections during different times of day. This can be converted to knowledge by analysing the data to create smart intersections which respond to traffic flow differently during different hours of the day based on invisible information gathered through traffic patterns data. Another use of the waiting time data could be appropriate quantities and placement of advertisements targeting the right audience based on statistical information regarding age, gender, employment, income level, nationalities etc.
