METHODOLOGY FOR ANALYZING THE AREAS OF WALKING ACCESSIBILITY OF SHELTERS DEPENDING ON THE TYPE OF BALLISTIC MISSILES USING MODERN GEOSPATIAL ANALYSIS TOOLS

Abstract

The article analyses the coverage of the walking distance of shelters in Mykolaiv city under conditions of potential danger. The capacity of existing and potential shelters was assessed, on the basis of which a conclusion was made about the need to create new shelters. The article considers methods of analysing the coverage of the walking distance of shelters depending on the type of ballistic shells on the example of the city of Mykolaiv using modern geospatial analysis tools. A practical solution to the problem of creating zones of walking accessibility of shelters depending on the type of ballistic projectiles using modern geospatial analysis tools is proposed. The purpose of the article is to increase the effectiveness of protection of the population in conditions of danger using modern means of geospatial analysis. Results: the main shortcomings of the existing system of ensuring security and proper informing of the population about shelters in cities were identified, the general situation with shelters in Mykolaiv city was analysed on the basis of the proposed methodology, which resulted in the construction of cartographic reports with calculated areas of coverage of walking distance depending on the type of ballistic missiles, which makes it possible to more effectively and reasonably assess the security situation and make management decisions. Conclusions: in the course of practical implementation of the methodology on the example of the city of Mykolaiv, it was found that the existing shelters in the city are not able to provide the necessary time accessibility and do not have the necessary capacity to save even half of the population in case of emergency, therefore, recommendations for identifying potential and creating new shelters to improve the safety of the population were created.
