Rozszerzenie kartograficznej metody koncentracji

W artykule zaproponowano rozszerzenie metodyki opracowywania map koncentracji przestrzennej. Omówiono także wyniki przeprowadzonych badań, wskazując iż dodatkowy parametr metody pozwala na uzyskanie przestrzennie spójnych klas obiektów dla poszczególnych wydzieleń tematycznych.

The ability to think of the map as a means of presenting not only real objects, but also abstract phenomena allowed for intensive growth of thematic cartography in 19th century. Later development of cartographic research method (analytical cartography) was the result of perceiving the map as a tool for examining spatial dispersion and interdependence of phenomena. The methodology of elaborating maps of spatial concentration is one of them. Contemporary technological development allows to eliminate calculation problems connected to elaborating such maps, it requires however making the rules of creating them more precise. The authors present the implementation of both the mosaic and the zone concentration method for a few selected phenomena. Whereas mosaic concentration maps were done according to original methodological assumptions (see F. Uhorczak 1971), an additional parameter of distance from zone nucleus was used for zone concentration. The parameter prevents concentration zones from expanding, which on previously elaborated concentration maps was the cartographer's task and resulted from his knowledge and experience. It was shown how the change in weight of that parameter impacts shape and distribution of concentration zones. It was also demonstrated how the change in base unit shape impacts the result of the method.
