Solution

The developed system is a web portal, the core of which is a service based on ArcGis geoinformation software products.

The geo-service is a database designed in the form of an interactive map of the Russian Arctic with the possibility of selecting indicators. The map displays the following data:

• Medical and demographic indicators (life expectancy, mortality, fertility, natural increase, etc.)
• Morbidity of the population (non-infectious, infectious, and parasitic morbidity)
• State of environmental factors (drinking water of centralized water supply systems, atmospheric air, the soil of settlements, etc.)
• Social and economic indicators (the percentage of people with incomes below the subsistence minimum, the ratio of average per capita income to the subsistence minimum, etc.).

In addition to standard solutions, ArcGis software has been developed to automate the processes of collecting, processing, and visualization of information, taking into account the existing system of statistical observation in the Russian Federation, as well as the administrative-territorial division of the Russian Arctic.

The key advantages of the created GIS-based system are:

1. Big data analysis identifies and maps risk areas (regions, districts, localities) by individual factors and their totality.
2. Spatial analysis of disease prevalence allows showing the risk territories for which unfavorable dynamics can be expected and forming proposals to improve the situation.
3. The possibility of semi-automatic processing of Big Data, spatially related to the places of compact residence of the population in the Russian Arctic allows forming fundamentally new approaches to the organization of socio-hygienic monitoring in the region.
4. The application of the developed algorithms of correlation, regression, and cluster analysis, integrated into the created software product, allows revealing regularities between the state of environmental factors and population health, and assessing the impact of these factors over a long period of exposure, which is impossible with the use of traditional methods without visualization on a cartographic basis.

Access to the service is provided through a personal account with the system of delimitation of rights for different categories of users.

As a tool for analysis and assessment of the health and sanitary-epidemiological situation, the geoportal can be used:

• By Rospotrebnadzor authorities and organizations in practical and scientific work;
• By research organizations of various profiles;
• By executive authorities (administrations) of the subjects of the Russian Federation in the development of comprehensive plans for the development of territories;
• In the educational process.

The software suite designed will not only acquire, analyze, and evaluate wealth of statistical information about the region, taking into account spatial reference to the territory, but also help automatize and optimize these processes. The outlook for using the portal are the elaboration of general schemes for the Arctic territories development, the planning of capital investment projects and minimizing risks during their implementation, the establishment of measures to prevent and reduce morbidity, the development of targeted social programs for various groups of the population, the launch of programmes for comprehensive improvement of territories and others.

On December 22, the launch of the Geoinformation Portal "Sanitary and Epidemiological Well-Being of the Population in the Arctic Zone of the Russian Federation" took place at the North-West Public Health Research Center (NWRC) of Rospotrebnadzor. Sergey A. Gorbanev, Doctor of Medical Sciences, the NWRC's Head, noted the great scientific and practical potential of the Geoinformation portal: "In fact, this is the first GIS-based information and analytical system in Russia, and possibly in the world, focused on the issue of sanitary and epidemiological well-being of the population in the Arctic zone of the Russian Federation. Its important feature is the capability to scale both in the geographical aspect and in terms of the database structure. We expect interest in the analytical capabilities of the Geoinformation portal not only from the bodies and institutions of Rospotrebnadzor, but also from the authorities of the Arctic zone regions, industrial enterprises, and healthcare institutions." The NWRC management representatives also highlighted the need to continue the research into the expanding of the Geoinformation portal analytical tools, the building of databases and methods of data processing, which implies continued cooperation between the North-West Public Health Research Center and the Laboratory of Industrial Systems for Streaming Data Processing. The following key tasks for the project development planned for the coming years are:

• Design and integration of complex statistical data analysis tools into Geoinformation portal;
• Expanding the list of sanitary and epidemiological well-being indicators;
• Geographical coverage expansion with the inclusion of territories directly adjacent to the Arctic zone into the Geoinformation portal.

The NWRC experts have begun to develop new terms of reference for the system under development, taking into account a wide range of tasks the Center is facing while studying environmental factors and public health in the Arctic zone of the Russian Federation.
