Spatial Threat Level Analysis

In the material the authors consider methods for the analysis of spatially-defined states, which are an indicator of certain threats. One such threat is the evolving COVID-19 epidemic. An essential part of the countermeasures, especially in the early stages, is the warning not to enter areas with an increased risk of infection, or in the case of partially quarantined persons - a warning not to leave the perimeter approved for movement. Modern mobile devices, smartphones, are a natural tool for personal alerting a person when entering a territorial area with undesirable consequences. Traditional methods for localization are considered, as well as a method for determining the coordinates of a mobile object using network stations of mobile operators. The mathematical bases are presented and an analysis is performed to evaluate the effect of the spatial analysis.
