   <abstract xml:lang="ru">
    <p>Предложен подход к исследованию лавинной опасности территории&#13;
на основе почти периодического анализа данных, в результате которого образуются интервалы единообразного поведения функции. Эти интервалы разделены равномерно отдалёнными границами, формирующими прямоугольную сетку в пространстве линеаризованных данных.&#13;
Предложен алгоритм исследования лавинной опасности горной территории, основанный на почти периодическом анализе линеаризованных данных, полученных в ходе полигональной трансформации исходного спутникового снимка горного хребта. По результатам применения алгоритма определена композиция равномерных продольных и поперечных интервалов единообразного повеления линеаризованных данных, формирующая систему критических пространственных барьеров исходного изображения, определяющих степень лавинной опасности близлежащих территорий.</p>

    <p>An algorithm for studying the avalanche hazard of a territory based on a nearly periodic analysis of data proposed, which results in intervals of uniform function behavior. These intervals divided by uniformly spaced boundaries that form a rectangular grid in the space of linearized data. An algorithm for studying the avalanche hazard of a mountainous territory proposed, based on a nearly periodic analysis of linearized data obtained during the polygonal transformation of the original satellite image of a mountain range. Based on the results of applying the algorithm, a composition of uniform longitudinal and transverse intervals of uniform behavior of linearized data is determined, forming a system of critical spatial barriers of the original image that determine the degree of avalanche hazard of nearby territories.</p>
