This definition of cartography, the most widespread one, reflects its technical aspects. At the same time, the modern view of geographic maps as graphic figurative-symbolic models of space leads to a stricter definition of the subject and method of cartography: the science of the representation and study of the spatial arrangements, combinations, and interrelationships of the phenomena of nature and society (and their changes over time) by means of cartographic pictures, which reproduce particular aspects of reality. This definition includes within cartography maps of celestial bodies and of the heavens, globes, relief maps, and other spatial models that use cartographic symbols. The subject of cartography (the spatial arrangement, combinations, and relationships of phenomena) and the development of topical maps are increasingly allying it with the natural sciences. The term “cartography” is also applied to scientific and industrial cartographic activity and to its results —for example, state cartography. It is in this sense that the term is included in the name of the cartographic and geodetic service of the USSR (the Central Administration for Geodesy and Cartography of the Council of Ministers of the USSR). Present-day cartography includes the following branches: (1) The theoretical foundations of the science, including the teaching of the subject and methods of cartography and map theory (or, more completely, the theory of the cartographic representation of reality). The latter includes the theory of cartographic projections and the theory of generalization and methods of representation (the system of symbols). It considers types and kinds of maps and their classification and analysis. (2) The history of cartographic science and map-making. (3) The study of cartographic sources (systematic survey and analysis of cartographic sources and relevant questions of scientific information theory). (4) The theory and technology of drafting and preparing maps. (5) The theory and methods of using maps. The problems of cartography arose during various periods of history and are in different stages of development. This has been reflected in the breakdown of cartography into separate disciplines: map studies, mathematical cartography, the compilation and design (or drafting) of maps, and the production of finished maps; cartometry is sometimes treated as a special discipline. In its present state, map studies includes the theoretical foundations of the science, its history, study of sources, and methods of using maps. Mathematical cartography, or the theory of cartographic projections, was the first to be established as a special discipline. Cartometry—the teaching of the use of maps to measure and compute coordinates, distances, lengths, elevations, and areas— has a long history; obviously, it constitutes just one method of using maps, but it is often used independently because of its practical importance and the antiquity and abundance of research. The theory and technology of drafting and making original maps has developed vigorously in the USSR under the name “compilation and design of maps.” The task of map-making includes the study and development of the means of representation in cartography, using data from semiotics, color studies, and engineering psychology, as well as methods of the graphic arts, and taking into account printing requirements. The uniqueness of particular types of maps—for example, geologic, soil, economic, and other maps based on the data of the corresponding sciences (geology, soil science, economic geography, and so on)—and the particular features of the compilation of such maps led to the development and separation of topical divisions of cartography: geologic cartography, soil cartography, economic cartography, and so on. These borderline disciplines belong to cartography according to method, but according to the content of the maps they belong to other sciences. Special training for cartographers also includes map publication (study of the development of methods for reproducing and duplicating maps) and the economics and organization of map-making. However, the former, which is based primarily on the physicochemical and technical sciences, belongs to typography, whereas the latter belongs to the economics of various fields of science and engineering. The oldest surviving cartographic pictures were made in Babylon and Egypt in the third to first millennia b.c.The first scientific foundations of cartography were laid in ancient Greece, where geographic maps were made that took into account the spherical shape of the earth. Ptolemy’s famous Geography (second century a.d.) was essentially a manual for the compilation of geographic maps. It included a map of the world and 16 maps of large subdivisions of the earth. The development of trade, navigation, and colonization in the age of the Renaissance and great geographic discoveries (15th and 16th centuries) aroused great demand for geographic maps, particularly world maps, which required the development of new cartographic projections and led to a general advancement of cartography. Medieval cartography attained its greatest development in the works of G. Mercator, whose atlas of 1595 is well known. The establishment of scientific cartography in Russia dates to the 18th century and is related primarily to the activity of the Geography Department of the Academy of Sciences, where the first complete Atlas Rossiiskoi (Russian Atlas) was prepared and published in 1745. In the 19th century military interests led to the need for detailed maps of terrain. In this period cartography was either considered to be a branch of geodesy or was restricted in its scientific interest to cartographic projections and, partially, to methods of measurement from maps—that is, to specific and relatively narrow mathematical problems. At the same time, the differentiation of sciences and practical needs in the second half of the 19th century brought about the development of many different topical maps (geologic, climatic, soil, and economic). The purely geometric treatment of cartography at this time hindered its development. New views of cartography took root earliest in the USSR, where the planned economy required multifaceted mapping of the country. As early as the 1930’s cartography came to be understood as the science of the methods and processes of compilation and reproduction of maps, which was a progressive idea in comparison with the previous concept of cartography. However, the study of the essence of maps and developing methods for their use remained in the shadow. The creation of major cartographic works in the USSR (among them the Great Soviet World Atlas) required that this gap be filled and that corresponding areas of cartography be developed. This led to the definition of the science that was cited at the beginning of this article. Letters written in 1920–21 by V. I. Lenin concerning preparation of the first Soviet geographic atlases, as well as other documents written by Lenin on questions of cartography, were of great value to the development of the ideological and scientific foundations of Soviet cartography. Specifically, they emphasize the importance of a complete, reliable, and graphic representation of phenomena in all their aspects, interrelations, historical development, and contradictions. Cartography is closely associated with geodesy and the geographic sciences. Geodesy provides exact data on the shape and dimensions of the earth, and topography and aerial photographic topography provide the primary cartographic sources—the large-scale topographical maps that are the initial basis for all geographic maps. The geographic sciences give the cartographer the knowledge necessary for making sound choices of the quantitative and qualitative characteristics of the phenomena being mapped and for their correct depiction, with due regard for regional features. In turn, the maps are an effective tool in geography, as in other sciences, for the study of the spatial arrangement, combinations, and interrelationships of all natural and social phenomena. The practical importance of cartography is determined by the value and uniqueness of geographic maps as graphic and exact spatial models that are widely used in the national economy, in culture and education, and for defense. Maps are produced either as the result of field surveys and the processing of data from them or in offices and laboratories by the use and revising of various sources, such as cartographic, geographic, economic, and statistical data. The methods of field surveying and data processing are the subject of topography and aerial photographic topography. Topical surveying, such as geologic and soil surveying, is a task of the particular kind of cartography (geologic or soil). The office and laboratory methods of drafting and making maps are developed in cartography proper. During office work a preliminary program is outlined on the basis of the purpose of the map being drafted: scale, cartographic projection, content (a list of the elements of the content, their classification, and the completeness and detail with which each element is shown), and methods of representation. Next, the necessary sources are selected and the phenomena being mapped are studied in the sources to determine the typical features and characteristics that should be shown on the map. The final program for the map is prepared by considering the results of this work. Work on graphic preparation of the original of the map (the compilation processes) follows. These processes include construction of the cartographic grid, complete or selective transfer of the content of the sources to it, generalization, and drawing of the original in the cartographic symbols established by the program. In the compilation of topical maps, the content of the sources is transferred to previously prepared or selected geographic positions. In the process of preparing a map for publication the base sheet of the map is often used to make (by lining or engraving on plastic) secondary smooth-delineation maps as fair copies to ensure the production of high-quality press plates. Preparation of the map ends with the publishing processes, as a result of which the map is printed in the required number of copies. In modern cartographic production, a group of specialists with various qualifications usually participates in the production of a map. Therefore, standardized scientific and technical supervision is needed in all stages of preparation of the map, including publication. This supervision is customarily called the editing of the map. International scientific ties in cartography first formed and developed within the framework of the international geographic congresses. Specifically, it was on their initiative that the Washington conference to select a uniform prime meridian was convened (the 1871 congress in Antwerp) and that the International 1:1,000, 000 Map and the International Bathymetric Map of the Oceans were compiled (the 1891 congress in Bern and the 1899 congress in Berlin, respectively). The formation in 1922 of the International Geographical Union, which, in addition to geographic congresses, organizes international commissions to work on the most important scientific problems, also promoted expanded research on cartography (national and regional comprehensive atlases, population mapping, land use maps, and international geomorphological maps). Finally, the formation in 1961 of the International Cartographic Association ensured systematic study of the problems of cartography based on cooperation among interested countries (convening scientific and technical conferences every two years and regular work by special commissions). The UN cartographic conferences that have met once every three years for the countries of Asia and the Far East (since 1955) and for the countries of Africa (since 1963) are important for the improvement of cartography in the developing countries. A particularly important recent international initiative is the International Map of the World, on a scale of 1:2, 500, 000, which has hypsometric representation of relief and gives a comparable picture of the continents and the world ocean (the map is being prepared by the cartographic and geodetic services of Bulgaria, Hungary, the German Democratic Republic, Poland, Rumania, the USSR, and Czechoslovakia). The current development of cartography is reflected in the rapid rise in the number of scientific journals and collections of periodicals dealing with cartography. REFERENCES“Pis’ma V. I.
