A 3D city model is digital model of urban areas that represent terrain surfaces, sites, buildings, vegetation, infrastructure and landscape elements in three-dimensional scale as well as related objects (e.g., city furniture) belonging to urban areas.
How many city models are there?
Urban planners, sociologists, along with geographers have come up with three models to demonstrate and explain how cities grow.
What are the 3 urban models?
Through the years ecological researchers have identified three major models of the geometry of city form: concentric zone, sector, and multiple nuclei .
What is an example of a sector model city?
The sector model of a city was based on Chicago ; the higher income residential was built along the desirable Lake Michigan and north of the CBD. Chicago closely implementing the Sector Model.
What are urban models?
Urban models are abstractions of reality that attempt to explain and predict urban spatial patterns and the functions of cities in a simplified manner . ... Most of these models focus on residential location as the foundation for the zones in their models.

What city model is Chicago?

Africa has the world’s fastest growing cities, and the impact that European Colonialism has had is clearly evident. The Europeans created prominent urban centers including ports along the coast.
What is the purpose of urban models?
Urban models are computer-based simulations used for testing theories about spatial location and interaction between land uses and related activities . They also provide digital environments for testing the consequences of physical planning policies on the future form of cities.
What are the models of urban structures?
Models of Urban Structure Sociologists, economists, and geographers have developed three models to help explain where different types of people tend to live in an urban area – the concentric zone, sector, and multiple nuclei models . The peripheral model is a modification of the multiple nuclei model.
What are the different models of urban structure?
To understand the way that urban areas, like Sally’s city, are arranged, let’s look at three popular models of urban structures: the concentric zone model, the sector model, and the multiple nuclei model .
What is christaller’s theory?
Christaller’s theory assumes that central places are distributed over a uniform plane of constant population density and purchasing power .
What is Borchert’s model?
The urban geographer John R. Borchert’s model focuses on the development of cities in relation to the development of transportation and communication . According to Borchert’s model a city’s urban layout owes a great deal to what forms of transportation and communication were available when the city was settled.
What is city sector?
The sector model, also known as the Hoyt model, is a model of urban land use proposed in 1939 by land economist Homer Hoyt. It is a modification of the concentric zone model of city development. The benefits of the application of this model include the fact it allows for an outward progression of growth.
