Urban Expansion Analysis of Bandar Abbas City Using Remote Sensing

This report examines the urban growth of Bandar Abbas City, Iran, between 1956 and 2015, utilizing remote sensing techniques to analyze land use changes. The study reveals a significant increase in the urban area from 402.6 to 5343.59 hectares, accompanied by a thirty-fold population increase. The report highlights the challenges posed by structural and natural limitations, with a substantial portion of the land being barren or occupied by infrastructure. It also discusses the influence of industries like steel, refinery, and aluminum, along with tourism, on the city's growth. The analysis incorporates city models to understand the urban structure, considering factors such as business areas, residential zones, green spaces, and industrial areas. The report concludes by emphasizing the need for sustainable and balanced development through effective urban management and control of irregular expansion, with consideration of land use and economic activities. Desklib offers a range of study tools and solved assignments to aid students in similar analyses.

Introduction
Bandar Abbas City is located in the South of Iran. Bandar Abbas City in Iran has experienced
urban growth that has led to change in its land use from 1956 to 2015 (Cervero, 2018). This
study purposes to examine the process of urban growth using remote sensing during this time.
Urban region area of Bandar Abbas city has changed from 402.6 to 5343.59 hectares between
1956 and 2015 and the population has increased more than 30 times in the last seventy years.
Due to structural and natural limitations , more than 78% of the land is barren , beach zones,
stone cliffs , and arable lands are taken up by built up areas. For sustainable and balanced
development to be realized in this city there must be control of the irregular expansion of the city
(Hegazy and Kaloop, 2015).

The City has a well established steel, refinery and alluminium industries that has led to increase
migration of people seeking employment. Tourist attraction centers is another functionality of
this city with an annual average of about 5 million tourists. Bandar Abbas has a population of
720000 people with an annual population growth rate of 2.3%.
Analyze the map based on different city models and discuss which of the models best suits
your city. Perhaps no one fits perfectly, then discuss different options.

Summarize method and results.
As a city grows, more land is needed to expand urban functions. Over time, the city's land use
will develop so that you can clearly find some main types of land use. We usually classify these
as business areas, residential areas, green areas and industrial areas.

The city center, or business area, is characterized by high-performance features due to the high
land prices. The city center is cramped and difficult to reach by car and therefore large shopping
centers are established in the outskirts of the city where there is plenty of room for parking
spaces and your car is easy to get to (Liu, et al,2014).
With increased distance from the center, the buildings are lower and housing more and more
homes. In Iran, residential areas are often found as suburbs with very varied services. The
suburbs originate from the suburbanization that occurred during the 1950s and 60's when the
country was industrialized. Due to high housing costs in the metropolitan areas, there is also a
certain relocation to the municipalities or rural areas in the developing countries (Lillesand,
Kiefer and Chipman, 2014). This migration process is called door banning. Because the
expatriates do not become farmers or small entrepreneurs in rural areas, doorbanks unfortunately
cause heavy load on traffic systems when people are commuting to their jobs in the city.
To ease the urban structure, green areas of various kinds are planned or preserved, for example.
parks as well as sports and recreation areas. The parks are often found on former "useless" land,
so-called. impediments.
Some areas of the city can also be a problem if they are abandoned when industries are laid down
or moving out to the outskirts of the city. Empty industrial premises are often converted to
offices, residential or cultural centers, while old port or rail areas are being converted to

residential areas. This "human recapture" of the urban environment is called reurbanization
(Huang, et al,2017).
The city's structure often reveals its age. Urban geography usually categorizes the urban structure
(= patterns) according to three models, namely the zone model, the sector model and the multi-
core model (Kneese, 2016). The first model originates from the agrarian early 19th century,
while the last is from the 1950s when the car began to affect primarily the development of North
American cities. In conclusion, the expansion and development of Bandar Abbas City must take
factor in the land to be used and the economic activities in the city.
