The maps portray the modifications which took place in an American town between 1948 and 2010. Generally speaking, some noticeable changes were made during the period.
Looking at the details, there were some significant variabilities. From the middle of town up to north-east, the surrounding lake with trees and the factories were situated in 1948. In 2010, these places were modified to a supermarket, commercial buildings and the airport. At the same time in the bottom right-hand corner of the town, the sports stadium replaced the church during this time. Residential houses and local supermarket were substituted with commercial buildings
By contrast, the residential houses which were located on the right side of the canal and the petrol station situated in the north of city did not change their positions all through a period of time.
Overall, in spite of some significant changes, the dimension of town did not alter. However, these variations manifest that the city developed gradually in terms of everything during this interval.
