ABSTRACT

A forest road system is a basic element of a technical infrastructure which enables conducting well-balanced forest management and meeting the postulates of the sustainable environment development. The correct designing of such a system for a specific mountainous forest area is a multi-layer activity, addressing a range of environmental features in the existing and future configuration, including but not limited to: relief, tree stand properties, hydrogeological conditions and a condition of the existing water system. A modern and effective analytical tool for geospatial data is GIS. The Forest Numerical Map Standard (FNM) contains a lot of essential information so that the analyses performed are useful in the road system optimisation.

   This article presents basic analyses conducted against FNM of a specific transportation
area (Łopień forest area in Limanowa Forestry Inspectorate, Southern Poland) and the Digital Elevation Model (DEM). By means of QGIS 2.12.0 Lyon, thematic maps were created and basic calculations were carried out concerning: the cataloguing of the existing state, technological typification of tree stands and design of a new road system. These were, among others, the following tree stand analyses: diversification of age, species composition, reserves, quantity and planned timber acquisition. The following was also performed: physiographical analyses concerning exposition and downslope, hydrographic analyses, presence and localisation of nature reserves, building properties of a subsoil, the present condition of the road system and a range of zones of making tree stands available. Furthermore, the operation of tools is presented consisting in filtering the features of elements for their selection, designing the route of new roads in the system with consideration of important properties of the transportation area, drawing a longitudinal profile of the terrain in the place of the designed road, calculating longitudinal slopes of such profiles, visualising road functions in the system on the map and other analyses.

Key words: GIS, forest road system, thematic maps, Forest Numerical Map data analysis.
