1.4.8. Self Assessment
Below, we listed various topics that have to be visualised in a thematic
interactive map. Choose one of those topics and find the best representation type
for it. Consider that there may occur some visualisation problems with your chosen
representation type, depending on the data set (e.g. overlapping of Wing Charts,
etc.). The data is referring to Switzerland but depending on the topic of your
choice you also have to define the exact referring features (commune, district,
canton or entire country).
You best have a look at the scheme
that we presented in chapter 1.4.2. Presentation of
thematic data. This scheme helps you to find the right representation
type.
After the definition of the representation type,
think about some possible interactivities that may be implemented in the map.
The
interactive parts can also have an influence on the choice of the representation
type. An Example: The number of tourists in Switzerland can be represented with
relative attributes (as a percentage: number of tourists per inhabitants of a
commune) or with absolute attributes (number of tourists for each commune). You
now
can say that you want to visualise the relative attributes in the map, but the
user
shall have the possibility to extract the absolute values with an interactive
tool
such as "click" or "on mouse over" effects.
Write a short essay about your results. Name the topic of your choice and
describe the representation type, the visualisation problems that may occur and
all
the interactive tools you want to implement. You may sketch some of your ideas.
Hand in your essay to the tutor.
