The two maps illustrate various changes the city has undergone since its opening in 1950 to the present.
Overall, the residential area has experienced major changes, with the most noticeable being the addition of the lake.
As can be seen to a city with 20.000 population from 1950, it is evidence to a business district area and a bridge in the middle of the map, which is at the top of the map. In the south of the business district area, it was surrounded by a river, and it is easy to see a major road at the center between a government building and the business district. At the business district, there were four major roads distributed in the north, west, south, and east. If we went to the east major road, it would be faced with an airport.
In the present, the biggest change on the map is the population, which is tenfold higher than the year 1950. It is true that the expansion of the residential area accounts for the center and airport in the left corner of the diagram. Following this, there has been built not only the government building at the bottom but also a dam and the bridge at the right hand of the map.
