The elements that make this a spatial problem is the location of the flooding of
the Cape peninsula, in particular the flood damage of Somerset West, the
location the buildings and infrastructure located within the 50 to 100 year flood
plain, the location of the porous and non-porous soils and the possible, the
elevation of the land and evacuation points for further flood risks.
We need to ask ourselves three main questions in order to identify what makes
this a spatial problem. Through these questions we are able to identify the spatial
Is it possible to clearly describe the problem and state what makes it spatial?
i.e. there we heavy downpours that led to the flooding of various parts of
the Cape peninsula, in particular Somerset West suffered extensive flood
Is it possible to specify a location on the earth’s surface that this was affected?
i.e. the spatial boundaries of Somerset West could be found and drawn on
Is it possible to specify some spatial features associated with the problem?
i.e. the location of the flooding, the location of the porous and non-porous
soils, the location of the evacuation points for future flood risk
The four main measurement scales are the Nominal Level of Measurement, the
Ordinal Level of Measurement, the Interval Level of Measurement and the Ratio
Level of Measurement.
The first element that I have identified is the flood damage of the Somerset
West area in particular the buildings and infrastructure in the 50 to 100 year
flood plain. The most sensible measurement scale to use here would be the
Nominal Level of Measurement. This is used to identify what buildings and
infrastructure were damaged by asking simple yes and no questions. These
questions could be: “Was most of the buildings and infrastructure...
