Новый аналого-цифровой метод формирования и использования картографического отображения геопространства с применением мультимедийных средств

Abstract

The article discusses the development directions of cartographic methods to provide users with geoinformation using modern digital devices. Explains the need to review the substantive essence, the system of symbols, use, information content and the peculiarity of the perception of cartographic information by users. A new method of cartographic support of the needs of the economy and society, which is based on a combination of the capabilities of analog traditional maps, mobile and multimedia cartography, is substantiated and proposed. Various ways of increasing the volume of cartographic information using traditional maps with special markers on them, multimedia files and mobile devices, introducing an interactive mode of working with a map, and also taking into account the peculiarities of the perception of digital mobile maps are considered. The authors proposed option for combining sources of geoinformation to increase the information capacity of a map by combining a traditional map and a set of markers that either store the necessary information in encoded form or represent a link to external sources. We analyzed the features of QR codes and highlighted the basic possibilities of using them when creating a new type of interactive map, and also performed statistical studies of this option regarding a quantitative increase in the amount of stored information. Five methods of creating sources of geospatial information and using it interactively, including in the field and in the absence of communication for the transmission of digital data, are proposed and a summary table of the advantages and disadvantages of the methods of analog-to-digital representation of spatial information is compiled. The results of experimental work are presented, including samples of new types of maps compiled.
