Extension of functions of cartographic images for transmission of geospatial information on mobile devices

Abstract

The article is devoted to the issue of expanding the functions of cartographic images for transmitting geospatial information using mobile devices. It discusses the functions of mobile mapping applications. Based on the classification of the main types of perception, a study was conducted on the correlation of user-accepted geospatial information with the means of its transmission. Since modern mobile technologies make it possible to obtain cartographic information with the help of visual, auditory, tactile perception, and also make it possible to sense space, movement and time, the map in combination with these types of perception becomes more intuitive. Actual in the visualization of the cartographic image on the screen of the mobile device is the question of exploring the user interface and displaying the contents of the map at different scale levels. In this regard, the requirements for interfaces are generalized, the principles necessary for the development of the interface of cartographic applications are formulated and presented, based on the condition: “Conditional sign — interface element”. The proposed principles can be divided into three groups: principles that define the general issues of building the interface of mobile cartographic applications, their structure as a whole and user interaction; principles governing the design of the interface of mobile cartographic applications; principles governing the development of mobile cartographic applications, taking into account the features of their use and new technical capabilities. Using the example of level-by-level compilation of elements of navigation charts, a conclusion is drawn on the correspondence between the display of spatial information on a mobile device and the user's perception of reality. Generalized features of cartographic image visualization in mobile devices, such as: intuitive readability, map adaptability, generalization by motion factor, multiscale and multimedia.
