The maps illustrate changes that have taken place in a particular city since 1950.
Overall, this riverside city has undergone significant changes, especially in terms of its residential zoning, landscape, and local transport infrastructure.
On the north bank of a river, the city accommodated a total of 20,000 people in 1950. The city was accessed by major roads dissecting the business district, running from north to south and east to west. There was an airport situated to the east of the city, and government buildings located on the southern side of the river, accessed via a bridge.
At present, the population sits at approximately 200,000 residents, a tenfold increase, causing the residential area to expand in all directions significantly. The river has been dammed, which has caused a large area of the river near the city to become a lake. Another business district has been established around the old government building on the southern side of the lake, as well as more government buildings further to the south of this area. A new road linking the southern and eastern roads has been constructed, while the airport has also increased dramatically in size.
