Development of a Software Package for Natural Risk Assessment Based on Repeated Remote Survey Data
The main objective of the paper is to present the outcomes of development of a model software suite for natural risk assessment analysis of hazardous exogenous processes. The work is implemented for thermokarst and soil subsidence processes along linear engineering structures. The software suite design rests on the approach of landscape mathematical morphology and employs the corresponding mathematical models for morphological patterns of landscapes. The software suit is capable of accounting for the linear structure impairments caused both by the hazardous processes appearing naturally prior to the engineering construction and by those appeared during the operation stage. Probabilistic assessment of the engineering structure impairment relies on the corresponding mathematical models. Multitemporal remote sensing imagery serves as the input data. The output data are the probability values of the engineering structure impairment for a specified period.
