Abstract: The article discusses the possibilities of using geoinformation technologies to study economic inequality. The methodology and technique of applying geospatial analysis in the study of wage inequality of employees of district cities of the Siberian Territory in 1926-1927 are shown. Statistical bulletins published in 1926-1929 in Novosibirsk were used as sources. Data were selected that characterize the salaries of employees of the district cities of Siberia for 8 quarters, covering almost 2 years – 1926 and 1927. During the development of GIS, a 1:3000000 scale map of the Siberian Region was digitized, on which there is a coordinate grid, the situation (hydrographic network and relief displayed by washing) and administrative division were plotted according to the zoning data of 1929. A series of maps was built reflecting the average salary level of employees in district cities, as well as the dynamics of wages based on quarterly statistics. The highest salary of employees is observed in Novosibirsk. It is noticeable that cities with low wages are concentrated in the south of Western Siberia. The growth rates of wages in cities show a greater variation than the average salary. The largest increase in wages is demonstrated by those cities in which its level was low or average. It can be stated that there are certain prospects in the use of geoinformation technologies to study economic inequality.

Abstract: In connection with the implementation of the project for the preservation of cultural and historical heritage associated with the creation and reconstruction of the Trans-Siberian railway, the authors of this article propose a technology for constructing three–dimensional cartographic images and its implementation on the example of one of the most famous sections of the Trans-Siberian Railway - the Tarmanchukan tunnel, which is one of the longest in the world. The purpose of this work is to build a 3D map of the tunnel using the Prism3D game engine. The article describes in detail the basic principles of building 3D models and 3D maps, describes the procedure for step-by-step creation of a 3D map of the Tarmanchukan tunnel with high detail and texture. The created product is, in fact, a virtual reality object, the closest possible copy of the original. To use it, there is no need to use a special helmet, it is enough to use the interface of the recommended programs. The high level of detail of the model allows you to get complete information about the object being modeled, including small details. As a result of the presented work, the most realistic map of one of the most famous tunnels in the world – Tarmanchukansky - was obtained. At the same time, the geographical features of the relief and landscape are fully reflected on the 3D map itself, access and viewing of which will soon be possible on the website of the Faculty of History of Lomonosov Moscow State University.

Abstract: The article discusses the creation of a thematic resource on the history of the Trans-Siberian Railway using modern Web-GIS tools which will provide for accumulating source information collected during research and presenting it in a form accessible for researchers. The online GIS allows one to work with the materials named in several modes:  interactive, tabular (with a description of the source base) as well as modes of editing information in the cloud storage database or in a limited mode of data input and data loading. The GIS project is represented by a set of vector and raster data transformed to work in a modern coordinate system: historical maps and diagrams, satellite images in the form of mosaics and image fragments obtained through available geoservices (Google, Yandex, Bing). Digital layers are also available which are generated and edited based on the digitization of historical and modern maps of different scales. Simultaneously with the work on the web-resource, the authors are creating the Transsib desktop GIS. The development and launch of the web-GIS "Trans-Siberian Railway" gives its users a number of new opportunities including the availability of generalized information and cartographic database on the history of the construction and operation of the Transsib as well as an opportunity for several users to work with project materials simultaneously, search for the necessary metadata information in the GIS, etc.

Abstract: The article addresses the creation and development of a spatial historical data fund. Nowadays we can talk about the readiness of the community of historical geoinformatics specialists to cooperate in the field of data storage and use. The article discusses similar studies both in domestic and foreign historiography. The authors propose a way to create a system for managing spatial historical data, consider some problems arising herewith and make suggestions about possible solutions. The main message of the article is that the amount of studies based on geo-information technologies has clearly begun to outnumber the quality. The article uses descriptive and historiographic methods. The main conclusion is the creation of a historical geoportal which, together with a historical spatial data fund, can be integrated into the national spatial data infrastructure. It seems that the idea to develop a historical geoportal should ground on both the convenience of fund navigation and the ability to perform analytical operations.
