Quantiles (percentiles) and Manual classification. Briefly describe these
classifications and under which conditions each of them is preferable. Include
sketches in your answer that clearly shows the differences between the three
types.

maps. What are the three types of maps called and what are the advantages
and disadvantages of them? Describe each map type and argue why each of
them should be used in that circumstance. Preferably, you can include sketches
to illustrate your answer.
1. Cartography, 10 p (HA)

4. Spatial Analysis using GIS, 10 (HA)
Measuring change over time using maps can be done in
different ways. Briefly describe in your own words how this is
done in the following case (see the following maps). Also
suggest how this change could have been presented in an
alternative way.
1) HA (10 p) Cartography
When doing a map based on quantitative data you have for example to decide upon the
number of classes and classification, i.e. which interval system to choose. Four common
classifications are natural breaks, equal interval quantiles (percentiles) and manual
classification. Briefly describe three of these four classifications and under which
conditions each of them is preferable. Include sketches in your answer.
2) HA (10p) Cartography
Code: ____
Five commonplace generalization methods in cartography are aggregation,
displacement, enhancement, selection and simplification of data. Explain these
methods mainly by making sketches that illustrate each method. In addition to the
sketches, add some few explaining sentences on each issue.

in your answer. 10 p
1) HA (10 p) Thematic maps, 10 p.

Briefly explain the following terms/techniques: a) topographic map; b) geoid; c) Robinson projection;
d) quantile classification.
(b) Thematic and geometric generalization, 6 p. (MS)
Explain the concepts thematic and geometric generalization. Also, provide three specific examples of
geometric generalization techniques.
Code: ____
3) a, Reasons for mapping change 5 p (OO)
Give three reasons for why we might be interested in mapping change over time.
b, Mapping pollution over time, 5 p (OO)
Suppose that you are tasked with mapping changes in the air quality in central parts of Umeå during
2014. The data has been collected on a weekly basis. Motivate what type of maps you would construct
(e.g., time series or tracking map), the type of change (e.g., magnitude or character), which
classification scheme and interval you would use for classifying the data, as well as other
variables/information that might be relevant to include in the map/s.
