The given maps represents, the enlargement of an area in Someland from 1990 to 2010.
Overall, drastic changes are shown on the area from the year 1990 to 2010. Lake, Hotel,Hydraulic dam and other things have been added. Whereas, so many other things have been demolished from the land science 1990.
In 1990, a river runs through mid of the land, from south to north of the map. The rare plants and animals were found on west of the river, and an ancient structure erect south to the forests (which stands north-west of the map). On east side of the river irrigation farmlands exists, near to which a village was built.
By 2010, a hydraulic dam was constructed on the river for “electricity production”. The ancient structure was demolished and made into a large lake, we can see sailing boats and fishes here too. The village was redeveloped, a little bit south to the hydraulic dam. The rare plants and animals extinct over these 20 years.
