In-Depth Information
topographic maps in a specific scale interval within a single nation during
a few decades or - at the other end of the scale - the development of topog-
raphic mapping on global scale and under a whole specified historical era.
All these analyses are represented by the red dot “c” in the plan
“INFORMATION ANALYSES” in
Figure 5
.
Analyses of this type could be e.g (for a topographic map): Which factors
are decisive for choice of the map´s content? Which factors guide the vis-
ual strength of different components of the map when designing it? What
is the influence of the reproduction techniques when displaying different
elements? Are there “a hidden agenda” when creating the map? We can
also compare the coverage of - in this case - the topographic maps in dif-
ferent regions, how they developed in time and space etc. The metamap
level in
Fig 5B
contains the necessary information in a systematised man-
ner. The development can then be related to a historical, political or mili-
tary background.
It is necessary to emphasize again, that point “a” represents several other
types of maps than the topographic one used here for exemplification
above and analyses based even on them will be represented by point “c”.
Figure 5:
The plane of INFORMATION ANALYSES contains all studies based on all maps
with identical composition of contents, in this case each studies based on this and similar
topographic maps, the metamaps showing their extent and development during time etc
and other related studies.
