Методика виявлення просторових аномалій руху суден та її використання при оцінюванні ризиків у системі морської охорони «Гарт-12»

Abstract

The article presents a method of detection of the spatial anomalies of vessel traffic based on «Hart-12» Information-Telecommunication Maritime Security System. Within this methodology, the authors propose a metric to determine the similarity of two routes of vessels based on discrete readings of their positions at different times, a clustering method for processing the data available in «Hart-12» and definitions for typical routes. When assessing risks of violation of border legislation at the maritime boundary, it is proposed to take into account the correspondence of the spatial data of the route to its descriptive part as well as average and maximum deviations from a typical route. When verifying descriptive data, the fuzzy matching algorithm based on the Levenshtein distance is used
