Modelling of the optimal vehicle route in terrain in emergency situations using GIS data

Popis výsledku v původním jazyce

Most navigation systems in transport are oriented towards the search of optimal paths (shortest or fastest), using vector GIS data. At the time of natural disasters and emergency situations is necessary to consider both of roads and terrain for transport. This article is focused on finding optimal routes in terrain, which contains a number of point, line and area obstacles. The most frequent point obstacles are trees in the forest. The paper analyzes the typical structure of tree stands in the forest, their characteristics in GIS databases, as well as dimensional parameters of vehicles moving in the forest. The quality of these data is a prerequisite for finding routes between point obstacles. Searching for the fastest or shortest route of the vehicledescribed in this article is based on the use of the relationship between the Delaunay triangulation and Voronoi graph, the application of Dijkstra's algorithm and the optimization of fractional line. The above-mentioned methods are also
