CONCEPTUAL MODELING OF THE DATABASE OF GIS MONITORING OF ELECTROMAGNETIC POLLUTION OF SETTLEMENTS

The article presents the results of conceptual modeling of the geospatial database for monitoring electromagnetic pollution of settlements. Recently, the world has seen a rapid increase in the number of sources and the level of electromagnetic radiation. This can negatively affect people's health and their environment. The analysis of the publications showed that today researchers have formed a theoretical base for assessing the impact of electromagnetic radiation on people and the environment, developed models of the propagation of electromagnetic waves, ways and methods of protection against their harmful effects. However, not enough attention has been paid to monitoring the electromagnetic pollution of settlements. Systematic measurements of electromagnetic field levels are carried out only by individual EU countries Systematic control of this type of pollution is not carried out in Ukraine, there are no regulatory documents regarding the procedure for its monitoring, but the maximum permissible levels of electromagnetic fields for the population are established. Data on the distribution of electromagnetic fields are interdisciplinary in nature and necessarily contain an indication of the location of objects. For their effective processing, it is advisable to use geo-information technologies. Based on the results of the analysis of the subject area of electromagnetic pollution monitoring, a conceptual data model was developed. It is described using UML tools. The model contains two sets of data. The basic set of geospatial data includes information about buildings of various purposes, land plots, streets, highways, railways, engineering communications, relief, soils, hydrography, territory zoning, facility addresses. The profile set includes data on electromagnetic radiation sources and their sanitary protection zones, control points, the results of calculations and measurements of radiation parameters, the relative level of electromagnetic fields and the building restriction zones. The proposed model can be the basis of the physical modeling of the settlement's electromagnetic pollution monitoring system.
