thematic maps, size and internal structure of geometric diagrams

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.

cartogram, area, cartogram, diagram cartogram

In this study different interpretations of cartogram, as the cartographic method used for expression of relative indices, are examined. It is not the same if cartogram is used to represent shares of the area surface (data relating to the surface of any area – district, region or state) or whether it is used to express shares of other nature (for instance number of unemployed of the total number of economically active population). Concepts of the area and diagram cartograms are defined and three causes of incorrect application of the area cartogram are explained in detail.

lichenometric dating, landslide, upper Holocene, Polish flysch Carpathians

Lichenometry uses lichen thallus increment as a time measure. Since the 1950s, it has been considered a useful method for dating rocky landforms developed over the past 500 years, as other methods are not suitable for such timescales. Rock walls and colluvial blocks are the basic elements in the morphology of rock landslides, which are colonized by the Rhizocarpon lichens. This paper shows the assumptions of lichenometry as well as its applications in geomorphological research in Poland and worldwide. The results of lichenometric datings of landslide-bouldery walls and colluvial blocks are presented. This study helps identify the landslide episodes instigated in historical time. The obtained results show that several generations of landslide-rockfall forms old as well as apparently new and active ones occur on the investigated slopes.

Western Beskydy Mts., flysch, morphotectonics, morphostructures, hypsometric analysis, morphometry, digital elevation model (DEM)

The aim of the presented study is to deal with specifics of the morphostructural formation of the Silesian and Magura nappes in the area of the Western Beskydy Mts. Both the nappe units represent basic geological systems of the flysch range of the Western Beskydy Mts. with considerably diverse displays of synorogenic deformations. By means of morphometric and statistical methods some differences in the geomorphology of the nappe units were identified and at the same time zones with displays of young Quaternary tectonics were defined. Digital elevation model (DEM) made it possible to map concrete relief displays of both passive and active morphostructuFGres.

residential policy, housing estates, transformation of urban structures, Europe, post-communistic countries

Housing is an essential need of mankind and a partial element in the comprehensive the study of environment. Adequate conditions and requirements for housing change in the course of the development of society, determining the society’s standard of living. The politico-economic situation in 20th century Europe conclusively affected also the character of urban structures. Central planning in the countries of Central and Eastern Europe was one-sidedly focused on the construction of housing estates. Since that time, the popularity of these structures has greatly faded in the whole region as many problems of a technical, social and area planning character appeared. For the last ten years these countries have been struggling with varied success for decentralization, privatization and deregulation of housing resources by means of newly formulated housing strategies.
