values of the maps are plotted. By 'topographic ränge' is to be understood the part of
the collection of landscape characteristics and elements represented on the map in
accordance with a certain legend. On the horizontal axis the map scale, the degree of
generalization and the symbolization are plotted (see fig. 3).
In the graph, the location of a number of topographic maps is indicated. The
location of the topographic maps 1 25 000 is marked with a rectangle. Within this
rectangle six topographical maps from various countries have been noted. 1t appears to
be possible to differentiate between the following types of topographic maps:
I. The Belgian type
This type, more than the other maps, shows a continuous topographic ränge. This is
specifically true for built-up areas and orography.
II. The Dutch type with a fairly wide topographic ränge, with the exception of
built-up areas.
IV.
