Własności metryczne wybranych odwzorowań anamorficznych

The lack of uniform distribution of geographical, economic or social phenomena on the Earth surface is natural. The concentration of objects or phenomena typical for some areas is inconsistent with theoretical assumptions in cartographical study that their distribution should be uniform. The problem with presentation of areas with diversified distribution of information occurs quite often. Good examples provide city centers and their historical districts. Responding to the need of presentation of that kind of geographical space maps of wide range scales (so called anamorphical maps) were introduced. This paper concentrates on some important anamorphical projections, which can be used in practice in the future, for example for typical surveying works. For analytical examination of the nature of that kind of projection, the discussion about the distribution of distortions for selected anamorphical projections was carried out. Test calculations were performed and numerical and graphic results let us better know specific features of that kind of projections and realize what are their application possibilities not only in graphic presentation, where efficient visualization is most important, but also in engineering works.
