The features of creating interactive web-maps on the territory of the city are considered. In a separate category maps created with Google, Yandex, OSM mapping a substrate with a certain set of points of interest (POI), and maps created with GIS applications. The technology of creating an interactive map is proposed, which includes the main stages: designing a mathematical basis, creating a geo-graphic basis, forming thematic databases, creating a web map. In the framework of this technology, the scale levels of the map are determined, and the choice of the cartographic projection is considered. The sources for creating an interactive map are identified, namely, the geographical basis, housing and utilities reform data, and thematic data. The interrelations of thematic objects with general geographical elements of the map content are established. A technological scheme for creating and filling a spatial database for a city site is presented. The stage of forming thematic data from various sources is considered. The technological scheme of creating an interactive web map is presented. The process of creating interactive logic is described. This technology allows you to easily make updates to the thematic database, which provides quick access to the information of the end user.
<p><strong>Abstract.</strong> Atlas mapping is one of the priorities of the modern mapping industry. It is connected both with the unceasing popularity of traditional atlases in the printing version, and with the active introduction and use of interactive electronic and web atlases, as well as with the development of atlas information systems. Currently there are no generalizing methodological solutions for automating the atlas compilation processes, despite the importance and perspectives of atlas mapping. In addition, there is no software which ensures all requirements for the design of the atlas. The use of geographic information technologies in atlas mapping doesn’t solve all the problems involved in creating atlases. For example, GIS can be used for solution of individual processes, e.g. the development of spatial and thematic databases, the creation of thematic maps, the cartographic generalization, the project of graphical index of maps into atlas pages, etc. But GIS doesn’t provide for the creation of a finished cartographic work with an integrated structure and content. This fact undoubtedly leads to the high cost and laboriousness of creating atlases, to the long-term design and the presence of errors in their compilation.</p><p>The Department of Cartography of the Moscow State University of Geodesy and Cartography (MIIGAiK) carries out research work on the development of the theory and methods of automating atlas mapping processes. The research is being directed to the speed of creation and improvement of the quality of general geographical, thematic and complex atlases. As part of this research, methods and algorithms for the automated creation of atlases have been developed, providing solutions to the most time-consuming and rather complex processes of atlas mapping, among which are:</p><ol><li>The development of an optimal atlas structure;</li><li>Design of the mathematical basis of the atlas (selection of a scale series, cartographic projections, format and layout);</li><li>Formalization of the creation of geographic base maps for atlas;</li><li>The formation and visualization of reference information of the atlas;</li><li>Organization, storage and use of spatial-temporary data in electronic atlases.</li></ol><p> Figure 1 presents the proposed solutions for automating processes mentioned above. The list of solutions may be different depending on the type of atlas being created (general geographical, thematic, and complex atlas). So the following options can be when developing the structure of the atlas. The use of a unified system of classification and coding of thematic maps and taking into account the degree of knowledge (study) of the object and mapped phenomenon is being used only for a thematic or complex regional atlas. The definition of possible combinations of territories shown on a single atlas map is used only for thematic or general geographical atlas. For each type of atlas, the formation and use of the reference information system of the studied atlases can be used, as well as the identification and formalization of factors affecting the inclusion of a specific section or a separate map.</p><p>The results of the research will ensure the efficiency of creating atlases and increase their quality. Also its will help to meet the increasing consumer demand for atlas map products, especially in the form of electronic atlases and geo-portal solutions.</p>
<p><strong>Abstract.</strong> The definition of scale series i.e. the identification of groups of scales in which maps will be created is one of the important tasks of designing the mathematical basis of the atlas. Map scale calculation based on the map format and the size of the mapping area is the most common approach to calculating the scale of the being created atlas maps. This approach allows to take into account the margins and layout of maps on the page. But usually these parameters aren’t known even at the design stage of a new atlas. So it is also necessary to take into account the completeness and detail of the content of the atlas maps at the stages of designing the atlas and determining the scale series for small-scale maps. The authors propose to carry out the calculation of scale series for atlas maps depending on the density of the mapped objects and the graphical load associated with it. In this case, both the density of general geographical objects (for example, settlements) and the density of objects of a thematic content (for example, volcanoes and earthquake epicentres, industrial centres, etc.) can be taken into account. These factors are important when designing general geographic atlases and when creating atlases containing a large number of thematic maps respectively. The method to determine the scale series for atlas maps depending on the density of the mapped objects is developed by authors and presented in Figure 1.</p>
