The maps illustrate the changes in Dalton between 1815 and 2015.
Overall, it is clear that the area underwent significant changes, with more facilities and fewer open spaces.
To the northeast, in 1815, the Dalton Hall is adjacent to the Hall Farm, surrounding the hall farm and vacant land, which are very large with few houses and few roads. In 2015, this area significantly changed to residential areas, which are denser. Although the changes are more obvious to the west, Dalton still maintains its original location but is surrounded by houses. To the northwest, in 1815, this location was only covered by Dalton Forest. In 2015, the Dalton forest was converted into many houses, the hospital, and some of the trees.
To the southwest, in 1815, this place had many trees and the Ford road extended across the river. By 2015, a part of Dalton forest was demolished to build the industrial zone with many factories and the red bridge across the river. To the southeast, in 1815, this area had only two houses and the Hall farm. In 2015, this area significantly changed with a big school, many houses, a hotel, and an airport, which is adjacent to the River Dal.
