The graphs compare the map of the area before the introduction of the hydroelectric dam in 1980 and its layout in 2000. Overall, the whole area underwent radical changes with the most striking being the introduction of the hydroelectric dam, the formation of a lake and the industrialization. Turning to the western side of the map in 1980, an ancient structure was located in the top left corner of the map and surrounded by a forest, mountain and a river, which ran from the north to the south of the map. To the south of the mountain and the historical site was an area for rare plants and animals. Looking eastward, between two big mountains, which stood in the top and bottom right corner, there was a zone for irrigated farmland and villages. Plus the farmland was divided into two separated zones by a little mountain to the east of the centre of the map. To the south of the little mountain was the village. After two decades, a lake was formed in the centre of the map, followed by the construction of a hydroelectric dam in the southern part of the lake. To the southwest of the river, electric wires were implemented along the river. Moreover, some facilities such as electric wires were introduced, and a village was relocated to the south of the dam. To the east of the lake, there were once irrigated farmland and a village was a hotel. In the western section, an ancient structure and area for rare plants and animals were demolished after the transformation.
