6. 2. Map as a Communication System
1975, A Robinson and BB Petchenik
• Evaluating map production and map
reading as a communication process
• Refining models of cartographic
communication
• Outlining problems with measuring
information content on maps and
information retrieved by percipient

7. 2. Map as a Communication System
• Define:
– map user/viewer/reader versus
– map receiver: one who by viewing a
map augments his/her understanding
of the geographic milieu that is his
previous conception of the real world.
= map percipient – have the power to
perceive

21. 3. Discuss problems with the paradigm
Cartography Communication Science
(MacEachren reading 1995)
a) Viewing cartography as a communication
science omits many ways people use maps
b) Scientific empirical research for improving
maps ignores contributions of art
c) Philosophical perspective/social theory: does
not accept maps as objective representations
of reality therefore rejects that any objective
research is possible
