Figure 2: City assets and products detailed categorization

Figure 2 has further broken down the three categories hierarchically.

City infrastructure: It refers to buildings, public spaces and infrastructure, and the digital infrastructure
(see figure 1).

a) Buildings: Buildings provide the essential space for a city to function, such as living and working
places, storage places for belongings and shelters for the needy. The types of different buildings
in a city include residential building such as apartments and houses, commercial buildings such
as offices and shopping malls, and public buildings such as hospitals, schools, religious, heritage,
government, military-related buildings, and other civic buildings that belong to the public sector.
b) Public spaces and infrastructure: A public space is an urban place that is generally open and accessible
to people in a city. They may include public squares, sports fields, and beaches. Infrastructures are
connective structures that enable people in a city to get the resources they need (e.g., from the
environment) and bring them to the city; or they may enable flows or cycles in city. Infrastructure
4
types include communication, water, energy, mobility (transport) infrastructure, digital and green
infrastructures, as specified below.

o Communication infrastructure: This includes telecommunications, radio, television, and internet
infrastructures (including analogue and digital transmissions through various physical media
such as copper, coaxial, fibre).
