The maps in question detail the transformation of Dalton between 1815 and 2015.
Overall, the area shifted from a predominantly rural and farming-based settlement to a more urbanized region. The key changes include the expansion of housing and road infrastructure, the introduction of new facilities for medical, industrial, and educational purposes, and the complete elimination of agricultural activities.
Regarding the western area of the map, in 1815, this section was dominated by a forest, and there was a river, which ran from north to south and ended in river dal, occupying the southern part, bisecting it from the east. To access this forest, residents would have to use a bridleway named “Ford” residing in the downstream of the river. By 2015, this part had been industrialised. With the forest removed, a housing area was erected in its place, separated from a new hospital by a new road to its right. The Ford bridleway was reconstructed into an extended road, with a bridge crossing the river and going through an industrial zone in the southwestern corner.
As for the eastern part of the Dalton, initially, there was a road that started from the northeastern corner and ended before reaching river dal, along of which was scattered housing units. To reach the Dalton Hall, people must head east on the bridleway which is mid-section of the road, which also led to a forested area in the middle of Dalton and a hall farm with cattles opposite of it. By 2015, the settlement had been renovated, with housing expanding throughout the east, replacing the forest and the hall farm. Bridleways were converted into conventional roads, with the addition of an educational institute to its north, and the relocation of dalton hall to a more northern part. Finaly, an airport is constructed just central-south of the the Ford road, and a hotel built in where the Dalton Hall once was.
