The maps illustrate the evolution that occurred in a certain city from 1950 to the present.
Overall, the city has experienced significant modifications. The most noticeable alterations have included the expansion of business district and residential area and the addition of infrastructure.
In 1950, the city’s population reached 20,000. The residential area was located in the north of the map, with a business district directly across from there, and there is four major road converging from four directions. The river ran along horizontal side of the map from southeast to southwest, with a bridge crossing over in the middle. A government building was established adjacent to the bridge along the river from the south. The eastern region was dominated by a airport, opposite the river to the southeast.
At the present, the city’s population increased to 200,000 people and the layout has exhibited significant changes. The business district and residential area have remained the former sites, but they have been expanded in the heart of the map, with a long lake running along and an untouched bridge as in the past. Also, a dam has been established at the end of the lake in the southeast and the river has flanked the residential area. The government building has retained in original position, but it has been narrowed to make way for the lake. There has been a bigger government building in the south of the map. The major road has been widen, which has led from the southeast to the south and crossed the lake with a bridge in the middle and toward the other main road in the east. The airport has remained unchanged but it has been expanded in the southeast of the map.
