Usage of Fuzzy Spatial Theory for Modelling of Terrain Passability

Abstract

Geographic support of decision-making processes is based on various geographic products, usually in digital form, which come from various foundations and sources. Each product can be characterized by its quality or by its utility value for the given type of task or group of tasks, for which the product is used. They also usually have different characteristics and thus can very significantly influence the resulting analytical material. The aim of the paper is to contribute to the solution of the question of how it is possible to work with diverse spatial geographic information so that the user has an idea about the resulting product. The concept of fuzzy sets is used for representation of classes, whose boundaries are not clearly (not sharply) set, namely, the fuzzy approach in overlaying operations realized in ESRI ArcGIS environment. The paper is based on a research project which is being solved at the Faculty of Military Technologies of the University of Defence. The research deals with the influence of geographic and climatic factors on the activity of armed forces and the Integrated Rescue System.

Physical-geographic factors of terrain trafficability of military vehicles according to Western World methodologies

“…The analysis, data quality control, and modelling of terrain trafficability factors based on probabilistic and statistical theories using the Bayesian theorem were applied in the work of Laskey et al (2010). Modelling using fuzzy logic in models and analysis of terrain trafficability was applied by Atkinson et al (2005), George et al (2017), Hofmann et al (20132015), Slocum (2003), Talhofer et al (2015) in raster analysis, where simple Boolean logic 4 was upgraded using the set theory. Gustafsson and Hägerstrand (2005) applied a special approach 4 Boolean algebra is a part of mathematical logic where the values of the variables are defined by logical operators "true" and "false", which are usually indicated by values 1 and 0.…”

“…The term "terrain trafficability" is used to determine the limiting factors that affect the mobility of vehicles outside the road infrastructure (Production of Cross-Country, 1959;Grabau, 1964;Military Geographic Intelligence, 1972;Schreier and Lavkulich, 1978;Donlon and Forbus, 1999;Wong, 2001;Saarilahti, 2002;Birkel, 2003;Rybanský, 2003;Jones et al, 2004;Gumoś, 2005;Kourdian, 2009;Hofmann et al, 2013;Hohmann et al, 2013).…”
