THE PROBLEM OF DETERMINING THE INTERNAL STRUCTURE OF GEOMETRIC DIAGRAMS ON TEMETIC MAPS

Year, pages: 2004, 267 - 276

The main objective of this paper is to design a method by means of which it is possible to determine the internal structure of geometric diagrams used on thematic maps. Note that this structure should map the internal structure of human-geographical entities, as for instance of settlements, industrial centres or of whole areas. However, in order to reach this goal, the precondition is to determine first the size of these diagrams. Therefore, the first part of the paper is briefly concerned with this problem. The principle being used in determining the size of geometric diagrams is the principle of direct proportionality, which means that the size of diagrams has to be directly proportional to the size of corresponding human-geographical entities or areas. The principle is mathematically formulated and then a general formula for the size of geometric diagrams is derived. Moreover, besides the general formula, formulae for the size of the most frequently used geometric diagrams, e. g. circle, square and equilateral triangle are also derived. The second part of the paper is explicitly concerned with determining the internal structure of geometric diagrams. The same principle, that is the principle of direct proportionality, is also used in this case. It means that the internal structure of geometric diagrams has to be directly proportional to the internal structure of human-geographical entities or areas. Again, besides the derivation of general formula, the formulae for circle, square and equilateral triangle are derived.
