The maps illustrate the developments which took place in the coastal town of Youngsville between 1980 and 2005.
Overall, a comparison of the two maps reveals a complete transformation from a largely rural to a mainly urban area.
In the year 1980, the town was a much greener residential area with a large number of trees and individual houses, but during the next 25 years, the town saw a number of significant changes. The most noticeable is that all of the trees in the south of the River Alanah were chopped down, with all the houses along the railway line being demolished to make way for skyscrapers. Moreover, a new industrial zone with warehouses and factories sprang up around the school and airport.
In contrast, only a few trees in the north of the river remained. The woodland was cleared and converted into a golf course, a park, and car parting facilities. Further developments were the construction of a stadium next to the north-east corner of the lake and the extension of the railway line from the river running directly to the north. A Marina was also constructed at the mouth of the river.
