Cartographic visualization of two-component quantitative features recognized in sampled form

In the contemporary cartography modelling of complex features’ distribution using the symbols or choropleth methods leads very often to discordance between the scale of background and the scale of main map’s content. Two kinds of accuracy are distinguished: geometrical and statistical. In the paper the unification of both above mentioned scales has been proposed according to the rudimental rule of coherent visual perception of pictorial model of “reality” characterising the system of coding used in cartography.
