shown. Forest management units “ribničko” and “rogatičko” achieve the best financial results, so they are able to invest more financial resources than others. Figure 10 shows the amount or length of constructed roads for each forest area in relation to the total road construction in the exploration area for the shown period. DISCUSSION Rasprava The combination of GPS and GIS technology represents a global trend with an inexhaustible range of applications when it comes to collecting and analyzing spatial information (Drosos et al. 2014) and a fast, efficient and cost-effective method of forest roads inventory (Gumus & Acar, 2003). Due to possible defects occurring during the recording of forest roads, the precision of the GPS device and the signal quality, further analysis of the recorded data is necessary. Çalişkan & Karahalil (2017) applied GPS tracking and formed a database on every road, while Lepoglavec et al. (2015) made a correction of recorded data using orthophotos, in addition to recording a forest path track with a GPS device in one pass. Pentek et al. (2003) recommend recording the so-called “Feedback Methods, i.e., two-way shooting paths to minimize errors. As already mentioned in this paper, a network of roads was created in the forests owned by Public Enterprise „Šume Republike Srpske” in 2016. Based on the analysis of the quantitative conditions in the network of truck roads in the Republic of Srpska, the density of primary forest traffic infrastructure is 9.28 m/ha and for public roads 11.21 m/ha. According to the above density of the network of truck roads, Republic of Srpska lags behind developed countries of Western Europe, in which the density of forest road networks reaches over 45 m/ha (Sokolović & Bajrić, 2009), but not so much behind the countries of the region. By comparison, the total length of roads used for forestry in Macedonia is 13,263.00 km, of which 3,326.00 km are public roads and 9,937.00 km are truck roads, which makes the density of truck road network of 13.43 m/ha (Trajanov et al. 2015). Based on data from 2009, the density of the network of primary forest traffic infrastructure in the Federation of BiH* (without the Herzegovina-Neretva Canton) was 10.9 m/ha (Sokolović & Bajrić, 2009). Pentek et al. (2014) reported that the density of forest roads in Croatian lowland regions was 9.05 m/ha, in hilly areas 11.26 m/ha, and 15.43 m/ha in the mountains, while in the karst area reached about 4.81 m/ha. Analyzing the network of forest and public roads that were used for forestry in Slovenia, Krč & Beguš (2013) point to the density of the road network of 24.8 m/ha. If we take only |
