The maps illustrate the transformation of a city (Youngsville) in New Zealand between 1980 and 2005. Overall, the most notable change was the industrialization of the city, with the introduction of factories and warehouses and the removal of trees and houses.
In 1980, the city was a green area with many trees. There was a river in the middle of the city dividing it into two parts. To the north, a lake occupied the center, surrounded by many trees all around, behind which was a hospital along the river, while houses were located vertically to the west. To the south, a school, several trees, and houses were positioned along the river, with a bench nearby, while a woodland and airport, together with a parking area, featured to the south. Rail tracks, together with a railway station, were available only on the northern side.
By 2005, the city had undergone significant alterations. While the lake and hospital remained unchanged, the houses and trees were demolished to make way for a park and stadium with two parking areas. The southern part of the city experienced the most noticeable changes. The houses were replaced by factories and warehouses, whereas the school and airport stayed in their original positions. The skyscrapers were constructed at the expense of trees and houses. Finally, railway tracks were also built to the north, running from the south with the railway station in the middle.
