Abstract
V nalogi smo prikazali, kakšna je ocena učinkovitosti dela pri ponovnem merjenju na stalnih vzorčnih ploskvah in kako potekajo kontrolne meritve. V gozdnogospodarski enoti Poljane smo izbrali modelno območje, v katerem smo izvedli meritve na 50 vzorčnih ploskvah. Pripravili smo terenske karte, snemalne liste in GPS sprejemnik za delo na terenu. Nato smo na snemalne listeevidentirali vse spremembe in napake ter s tehnologijo GPS ocenili natančnost središč vzorčnih ploskev, ki so bila določena v letu 1997. Večina odstopanj med izmerjenimi vrednostmi in pravimi vrednostmi koordinat za središča vzorčnih ploskev je bila manjša od 15 m. Meritve smo tudi časovno spremljali in jih nato analizirali v preglednicah programskega orodja EXCEL. Poraba časa za izdelavo ploskve je naraščala z gostoto dreves v sestojih. Z uporabo GPS je bilo delo pri iskanju vzorčnih ploskev lažje in hitrejše, za določitev središč pa smo potrebovali podatke o polarnih koordinatah dreves, drevesnih vrstah in njihovih premerih. Čas za meritve na vzorčni ploskvi je ostal enak kot pri prvem merjenju.

ǂThe ǂwork effectivness evaluation of permanent sampling plots remeasurements in the Poljane forest management unit |
Secondary abstract: |
The thesis shows the work effectiveness evaluation of permanent sampling plots remeasurements. In the Poljane forest management unit, a pattern area was chosen where measurements have been accomplished on fifty (50) sampling plots. Maps, recording leaflets and a GPS device were prepared for field work in the forest. The evidence of all possible changes and mistakes was collected, and GPS technology was used to assess the accuracy of sampling plotcentres established in 1997. Most deviations between the measured values and the real values of sampling plot centre coordinates were less than 15 metres. Time used for measurements was monitored and then analysed in the tables of EXCEL programme tool. Time used for remeasurement a plot increased with stand dinsity. The use of GPS technology made the search for sampling plots easier and faster, in order to establish the centres, data of tree polarcoordinates, tree species and their diameters were needed. Measuring on the sampling was simular as the first time. |
