Povzetek

Predhodno vrisane vlake v gozdarsko karto so dobra podlaga za podrobno gozdnogojitveno načrtovanje in izvedbo gozdarskih del. V praksi prihaja do odstopanj pri metodah GPS izmere in terestrične izmere situacije vlake. Terenski del diplomske naloge smo opravili v Gozdnogospodarski enoti (GGE) Črmošnjice, v oddelku 1. Oddelek spada v gozdnogospodarski razred dinarsko jelovo-bukovi gozdovi na najboljših rastiščih, in se razteza na 830 do 910 metrov nadmorske višine. V oddelku smo vse vlake izmerili z GPS in terestrično metodo merjenja vlak. Vse vlake smo istočasno merili z obema metodama. Primerjali smo razlike med izmerjenimi dolţinami vlak in odprtost gozdov. Vse podatke smo obdelali v programu MapInfo Professional 11.5, kjer smo vlakam, merjenim s terestrično metodo, zarisali še vlake, kjer smo upoštevali magnetno deklinacijo. S terestrično metodo smo izmerili 155,41 m/ha vlak v oddelku, kar znaša 76,07-odstotno odprtost oddelka, z metodo GPS paso izmerili 161,83 m/ha vlak, kar znaša 79,55-odstotno odprtost oddelka. Metoda GPS je relativno natančna, če je dober sprejem signala. Terestrična metoda pa je zamudna in zahteva pomočnika, vendar je bistveno bolj natančna odmetode GPS. Za potrebe gozdarstva je metoda GPS dovolj natančna metoda za merjenje gozdnih vlak. Z obema metodama ugotavljamo, da je odprtost oddelka komaj zadovoljiva.

Sekundarni naslov: A comparison of the terrestrial and GPS methods in forest trail condition measurements
Sekundarni povzetek: Trails that were drawn on the forestry map beforehand represent a solid basis for a detailed silvicultural planning and forestry work performance. In practice, there are discrepancies between the GPS measurement method and the terrestrial measurement of the trail condition. The field part of the Diploma thesis was carried out in the Forestry Unit (FU) Črmošnjice, Section 1. The relevant section falls within the forestry management class of Dinaric fir-beech forests occupying the best sites at 830-910 metres above sea level. In the section, we measured all trails using both the GPS and the terrestrial measurement methods. The trails were measured by these methods simultaneously. We compared the differences between the measured trail lengths and the openness of forests. All data were processed using the MapInfo Professional 11.5 software, where the trails measured by the terrestrial method were added trails where we also considered magnetic declination. With the terrestrial method, we measured a total of 155.41 m/ha of trails in the section, which represents a 76.07-percent openness of the section, whereas with the GPS method, we measured a total of 161.83 m/ha of trails, representing a 79.55-percent openness of the section. While the GPS method is relatively accurate if the signal reception is good, the terrestrial method takes longer and requires an assistant, but it is far more accurate than the GPS method. For forestry purposes, the GPS method is accurate enough for forest trail measurements. Using both methods we have come to the conclusion that the openness of the section is barely satisfactory.
