Abstract

In this study, main factors for path tracing (Road selecting) were investigated to study principle-digitized maps including slope, slope direction, soil, volume per hectare and ecological capacity units using GIS techniques. Namkhaneh district in Kheyroud Forest (Training and Research Forest of Natural Resources Faculty of Tehran University) at the east of Nowshahr close to Caspian sea (Mazandaran province) due to complete and exact geographical information was selected as the area of this research. Digital maps were produced and analyzed by GIS and Arcview software. The maps of soil, slope, directions of slope, bedrock and volume per hectare were categorized and classified. So surface of each classes were classified in tables to divide the research area to different units for road selecting. Finally it was decided to select the best area to plan forest road with effective factors. To design the optimal forest road, we used the GIS techniques. It was concluded that using GIS and computerized analyzing cause to economize in time, costs and to minimize environmentally damages.
