The given maps illustrate the modifications in a town where a hydroelectric power dam was built between 1990 and 2010.
A glance at the map reveals that the small town had changed into a massive business town over a period of 20 years.
By 1990, the river was located in the middle of the town. To the East of the river, irragted farmlands are close proximity to the river while villages are a long distance away from the river. In addition, mountains surrounded the farm and villages. On the West of the river, there were rare plants and animals which are nearly identical to the ancient structure. On the top left-hand of the river, there was a forest.
In 2010, a hydroelectric power dam was bulit in the North of the river. The dam was surrounded by two mountains on both sides. Except for the villages, everything around the river has changed into a string of electricity. Looking to the North of the town, the hotel was constructed directly opposite the lake.
