Geoinformation Technologies in the Reconstruction of the Social Space of Siberian Cities at the Turn of the 19–20th Centuries (Case Study of the City of Tobolsk)

Abstract

This article presents the experience of creating the historical geographic information system "Siberian Cities at the Turn of the 19-20 th Centuries" (Case Study of the City of Tobolsk) focused on presenting online results. The structure of the article corresponds to the main stages of GIS creation. At the first stage, the main attention was paid to the methods of preparation and input of cartographic material, due to the lack of a mathematical framework for historical maps. The affine transformation algorithm has been chosen as the main algorithm for working with the map of the city of Tobolsk, which allows to place the map sheet in a modern coordinate system (WGS84), with a limited number of fiducial points, correctly. The second stage was aimed at determining both the sources of demographic, social, economic, and spatial data, which will become the basis of the basic vector-raster layers. The source was a set of census forms of the First General Population Census of 1897 for 8 cities in the Tobolsk Province. The third stage is devoted to the Web-GIS creation. A pilot version of the project with the reconstruction of the urban space of Tobolsk at the turn of the 19-20 th centuries was created on the platform NextGISWeb. It is concluded that geoinformation technologies application is aimed not only at visualization and presentation of data from different sources, but also at creating a tool for spatial analysis of demographic, social and economic factors, studying the features of the various social groups resettlement and reconstruction of the social space of the city as a whole.

“…Geospatial analysis could be used to overcome various kinds of problems in cities (Bryukhanova et al, 2018). Algorithm based applications are used in environmental related geospatial analysis (Nikolov et al, 2015).…”

Automated map of reproductive losses in the Far North region of Russia

“…Globally, there are 3.2 million stillbirths and abortions every year, the vast majority of which occur in least developed countries. The prevalence of reproductive losses is typically about 1% of all births in more developed countries of the world and can exceed 3% in the less developed regions [1]. However, each country has its own characteristics of monitoring the dynamics of this indicator.…”
