Final answer:
The subject of the question is urban morphology and how it ensures a relatively uniform urban character even if sections are designed separately by different architects and planners.
Step-by-step explanation:
The concept described in the question is that of urban morphology. Urban morphology refers to the organization and layout of a city in space. It includes the physical structure of the city, such as its buildings, roads, and open spaces, as well as the patterns of land use and development.
For example, even if different sections of a city are designed separately by different architects and planners, a relatively uniform urban character can be achieved through the deliberate planning and coordination of various elements that contribute to the overall urban form.
