Scale series
defines a discrete set of scales within scale range in which
map compilation and design is made. In topography scales are usually
reduced by 2-2,5 times. This rule allows gradual transition and sufficient
degree of control over the map look and can be used for providing scale
series (
Figure 1
).

Scale range and scale series
Map projection should be constant or gradually changing to provide cross-
scale coherence.
2.2 Database design: structure and content
Database content for hypsometric mapping consists of relief and addition-
ally hydrographic data. All other layers, such as settlements, borders, and
transportation are optional and their inclusion depends on the purpose of
the map. We can divide data into three functional groups: base, auxiliary
and analytical (
Table 1
).
