Here's my full essay for this map question:
The diagrams illustrate some changes to a small island which has been developed for tourism.
It is clear that the island has changed considerably with the introduction of tourism, and six new features can be seen in the second diagram. The main developments are that the island is accessible and visitors have somewhere to stay.
Looking at the maps in more detail, we can see that small huts have been built to accommodate visitors to the island. The other physical structures that have been added are a reception building, in the middle of the island, and a restaurant to the north of the reception. Before these developments, the island was completely bare apart from a few trees.
As well as the buildings mentioned above, the new facilities on the island include a pier, where boats can dock. There is also a short road linking the pier with the reception and restaurant, and footpaths connect the huts. Finally, there is a designated swimming area for tourists off a beach on the western tip of the island.
