Abstract

The article is devoted to current theoretical issues of modern cartography. The paper puts forward the concept of metacartography, which laid as the foundation for the Theory of Cartography as a science. The author of this concept is the outstanding Georgian cartographer Alexander Aslanikashvili, who is the founder of the theory of cartography. This concept, which in a new way comprehended the main categories of cartography (the subject of cognition of science, the method of studying a certain side of reality and language) by means of which cartography examines its subject, made it possible to raise some questions of theoretical cartography for research: 1) temporal synthesis; 2) timescale; 3) dynamic generalization.

The temporary synthesis in the article is considered on the basis of the results of a theoretical study of A. Aslanikashvili, cartographic forms of analysis and synthesis. Temporal synthesis is studied by the example of diurnal state maps of natural-territorial complexes (steks). The process of temporary synthesis of the so-called “multi-temporal maps” is carried out for one year at three levels: 1) synthesis of dynamic maps for one month; 2) synthesis of dynamic maps for one season; 3) synthesis of dynamic maps for one year. As a result of the temporary synthesis of stacks maps, one synthetic map is compiled without loss of the initial spatiotemporal information. In the process of mapping there are used the so-called “spatiotemporal” diagrams. A new concept of “mapped time” was introduced.

In cartography, two types of scale are investigated: a) the scale of space (degree of abstraction) and b) the scale of content (degree of generalization). The article studies the timescale when mapping stacks. In the work, this concept is defined as the degree of generalization of the essence of the development of the mapped phenomenon.

The article explores another issue — dynamic generalization. The study is based on stacks’ maps for one year. It was found that dynamic generalization depends on the “degree of syntheticity” of the stecks maps. Dynamic generalization is in direct correlation with the number of dynamics maps of the spatiotemporal model phenomenon.

The issues of temporal synthesis, time scale and dynamic generalization are in close relationship with each other. For example, dynamic generalization is the result of a temporary synthesis, and these processes are carried out with the presence of a time scale.
