contour map of northern part of Cheung Chau :
From the Cheung Chau’s contour map drew by The Survey and Mapping Office, we saw contour lines in two parts have many differences.
First of all, every contour line in northern part is very close to each other, and its highest point is 95meters. The closely spacing contour lines mean the slope is steep. Steep slope is not suitable for building houses. The evidence is that Cheung Kwai Estate and Pak She San Estate are build on the only one flatland. In the other areas of the northern part are rarely seen buildings. Furthermore people must take a risk of landslides. In raining days, steep slope is the main factors causes landslides.
To the contrary, contour lines in southern part are further apart from each other, that means slopes in southern part are gentle and there are more flatland. It is suitable for building, hence southern part has much more settlement then that of the northern part. Besides, highest point in the southern part is 60 meters. It is shorter than northern part by 35 meters.

Smart in observing the differences from maps :)
