Primerjava terestrične in GPS metode pri meritvah situacije gozdnih vlak : diplomsko delo - visokošolski strokovni študij - 1. stopnja = A comparison of the terrestrial and GPS methods in forest trail condition measurements : B. Sc. Thesis - professional study programmesŠercelj, MaticPredhodno 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.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [M.
