The diagrams illustrate how town Dalton has changed between 1815 and 2015.
Overall, it is clear that town Dalton has undergone significant changes, with the most noticeable being Dalton forest and hall farm.
In 1815, the Dalton forest was located to the west and there was a River Dal to the south of the town. In the east of the Dalton forest, there was a hall farm next to Bridleway and near River Dal. In addition, a little house on the right of the hall farm had a main road through from south of the Bridleway to north of Dalton and beside the way had a few houses and horses.
In 2015, looking first at the map, the tower Dalton transformed into an urbanization, when the Dalton forest was extended towards the west to construct the hospital and houses. In the vicinity of the river dal built an airport and a little industrial zone, houses. Furthermore, the hall farm was converted into a school and houses and there was a bridge across between the town Dalton and industrial.
