oa Classification of cartographic geoimages as a component of geoinformation builder

With the increase in the number and variety of types of geoimages and the possibility of their design there is a problem of choosing the optimal type. One of the solutions for effective modelling of geoimages with given properties is to create an interactive system for designing geoimages. On the way to its implementation, one of the methodological issues is the creation of a classification of geoimages, in particular, cartographic. To describe the set of cartographic geoimages, we select objects, indicate their constituent elements and properties on the basis of which the features of classification groups of systematization are created. In addition to maps, cartographic geoimages also include plans, cartograms, mosaic cartogram, and others. To form a classification system, the properties of cartographic geoimages are studied and a system of features is developed. Among the properties are taken into account: 1) spatio-temporal similarity; 2) semantic compliance; 3) abstractness; 4) selectivity; 5) syntheticity; 6) metrics; 7) unambiguity; 8) continuity; 9) clarity; 10) readability; 11) visibility; 12) high informativeness. Based on the composition of elements and properties of maps, many objects of classification of cartographic geoimages are determined and the system of features (basics of classification) is expanded. The main classification features include those related to the cartographic image: the method of scientific research, subject (content), degree of reduction, spatial coverage, temporal correspondence, purpose, degree of schematization, degree of formalization, degree of objectivity. The features that apply to the whole work as a whole include: image form, method of use, design, method of manufacture, language of publication, storage media, format, breadth of the topic. On the basis of the formed system of classification features the classification of cartographic geoimages is developed.
