The maps illustrate how a coastal town called Portland changed between 1950 and 2007.
Overall, the town underwent a number of dramatic changes, the most important of which are the disappearance of open green spaces and the industrial area to make way for residential, commercial and recreational facilities, the expansion of infrastructure and the enhancement of accessibility through new road networks.
In 1950, grassland occupied both sides of the main road. However, by 2007, this green areas were replaced by various buildings. On the western side, a cinema and a row of shops was constructed, while on the eastern side saw the addition of a row of stores and two rows of houses. A new road also was introduced, liking these newly development and improving connectivity across the main road. Similarly, the industrial zone in the northwest was converted into a park and an adjacent swimming pool by 2007.
Meanwhile, the original park, which was situated in the northwest side , was removed to the opposite side of the town, next to the new swimming pool and upgraded into a multi-storey parking space. The main road was extended, providing access to a newly constructed for yacht marina , which was accompanied by a modern apartment complex being built alongside this marina.
