Abstract: The article studies spatial mobility and information dissemination within the medieval space. The research object is the factors of information conductivity such as geographical activity of the population and individuals as well as general spatial characteristics such as topographic conditions, population density and communication routes. The author pays special attention to the geographical outlook of the authors of narrative sources and their ability to remotely monitor Henry IV’s movements. Particular attention is paid to the influence of geographical imperatives that determine the content of sources. The author explains the distortion of localizations and inconsistencies of dates. The research method is the predominant application of the cartographic method followed by the space-time analysis. The research data were presented as a chronologically oriented geoinformation system. The research novelty is the topics raised. These are the information dissemination in a specific historical context and its influence on various aspects of historical processes. The author also stresses the importance of regular spatial activity of the population for studying historical geography of the region and potential and productivity of the information dissemination from the viewpoint of narrative sources analysis. From the viewpoint of methodology, the research significance is to demonstrate the capabilities of the complex geoinformation project for solving multiple problems. 

Abstract: The study aims at unifying the technique of historical mapping and creating a database of symbols for historical maps and geoinformation systems. The author substantiates the advantages of a general symbol set to simplify the reading of cartographic materials and formation of a uniform standard to improve interaction between specialists. Basing on a variety of examples from atlases and cartographic materials the author analyzes historical map legends. He finds optimum solutions providing for the choice of symbols and legend structuring. Comparative method is used. The author examines the existing lists of standardized symbols in other domains of cartography and compares different situations of legend formation in historical mapping. Chronological approach is employed as well to demonstrate the association of map structure complexity with higher requirements to legends. The main research value of the article is the formulation of methodological and technological grounds providing for creation of uniform database of historical map symbols. It is the first attempt to move forward within a sector of historical mapping which somewhat lacked previous base. The article presents the general structure of the reference symbol database, its main resources, the ways of its seeding as well as the algorithm of electronic symbol database creation as a full value tool to form historical maps and geoinformation systems. 

Abstract: The article studies functions and software for historical geoinformation systems. The research object is historical geoinformation systems, dynamical GIS-projects creation technologies and means of spatiotemporal analysis. The author considers separate structural parts of IGIS-resources creation service in detail. Emphasis is laid on auxiliary materials for historical GIS-cartography, in particular, to the sample base of conventional values and means of historical geoinformation systems unification. The study employs descriptive and comparative methods to demonstrate advantages of the proposed GIS-editor conception for historical maps and projects better. The author describes his variant of a specialized historical geoinfirmation system editor that takes into account specific functions of spatiotemporal analysis. Distinctive features of this resource in comparison with common editors are considered as well. The article concludes that historical GIS-projects need specialized software and functions and only close cooperation of historians and GIS-specialists will lead to an optimum tool set of historical maps and geoinformation systems.

Abstract: The article studies a technique and technologies of dynamic historical GIS-projects development and the employment of spatiotemporal analysis to study historical processes. The study covers geoinformation systems, the use of cartographical method in history, electronic cartography, historical process modeling. The author pays special attention to a heuristic work with a historical GIS-map as well as regularities by searching for synchronized and consecutive alterations of attributive and metric data of map objects. The main method employed is a comparative one. The comparison is drawn between historical and mathematical GIS-projects. Historical geoinformation systems at hand have also been compared to analyze and search for more preferable variants. The research novelty is an attempt to set up basic principles of spatiotemporal analysis when working with historical GIS-projects. The author presents his own variant of a dynamic geoinformation system allowing for historical process modeling. The article concludes that historical geoinformation systems are a particular class of GIS-format projects demanding specific methodical and technological approach as well as development of specific functions for spatiotemporal analysis.
