GEOINFORMATION-CARTOGRAPHIC SUPPORT MIGRATION AND POPULATION STUDIES: TECHNOLOGY, METHODS, DATABASES

The article analyzes the methodology of geoinformation and cartographic support of studies of migration and demographic processes. On the basis of international and in-house experience developed technological features of GIS technology for the organization and management of big data (big data). As the most effective method of spatial data analysis, multi-scale monitoring is proposed, based on the application of geoinformation practices that allow not only qualitatively accumulate information, but also visualize it. The team of authors has been studying migration and socio-demographic processes in Russia for many years, actively uses geographic information and cartographic approaches as research support, develops cartographic materials [2]. Materials and methods of research: A detailed analysis of the sources and types of information that fill the database of spatial data, which are used as the data of current population records (state statistics Committee), national census data, information obtained in the course of sociological surveys and processing of arrival and departure coupons for a long period of time. The information is systematized by blocks, which simplifies further data processing and obtaining analytical and cartographic reports. The results of the research and their discussion: The analysis of the methods and methods of cartographic visualization used to support research: the centrographic and typological method, etc. Prepared during the study of migration and socio-demographic processes cartographic material is systematized in the form of a cartographic database. This approach allows you to store the results and allows you to quickly use in research and practice. The main conclusions and discussion: The methodology of geoinformation monitoring of demo-migration processes has been tested and proved its effectiveness, which is reflected in the series of published publications «Migration processes in Russia. Atlas» [2], «Ethnic Atlas of Stavropol Krai» [3], «Ethnic aspects of urbanization in Russia» [9].
