Abstract

Tehnološkim napretkom i povećanom dostupnošću novih tehnologija kao što su bespilotne letjelice dolazi do sve veće njihove implementacije u operativno šumarstvo. Jedna od mogućih aplikacija ove suvremene tehnologije je i prilikom projektiranja šumskih cesta. Naime, iako je Republika Hrvatska uložila značajna sredstva u izgradnju šumskih cesta, još uvijek ima nedovoljno otvorenih šumskih površina na kojima je potrebno planirati te projektirati šumske ceste. U tu svrhu, provedeno je istraživanje mogućnosti primjene bespilotne letjelice za potrebe prikupljanja terenskih podataka nužnih za provedbu faze projektiranja šumskih cesta. Na području Uprave šuma podružnica Delnice, šumarija Vrbovsko, G.J „Miletka“, u odsjecima 44c i 44d bespilotnom letjelicom DJI Mavic 3 Enterprise snimljena je trasa planirane šumske ceste u dužini od 860,9 m. Temeljem snimljenih aerofotografija generiran je oblak točaka naknadno klasificiran automatskom i ručnom klasifikacijom iz kojega su izrađena dva digitalna modela terena istraživanog područja. Daljnjim analizama utvrđivane su sličnosti/razlike u prostornim podacima koordinate (Z) na terenskim točkama pri izmjeri normalnih poprečnih profila šumske ceste.

Abstract (english)

Operational forestry is increasing implementation of new technologies, such as unmanned aerial vehicles. One of the possible applications of this modern technologies is for forest road design. Although the Republic of Croatia has invested significant funds in the construction of forest roads, there are still insufficient open forest areas (areas with low accessibility) where it is necessary to plan and design forest roads. For this purpose, possibility of using an unmanned aerial vehicle for field data survey necessary in forest road design was tested. The route of the planned forest road in the length of 860.9 m was recorded by the DJI Mavic 3 Enterprise unmanned aerial vehicle in the area managed by Forestry Administration Delnice, Forest office Vrbovsko, management unit "Miletka", sections 44c and 44d. A point clouds were generated based on aerial photographs, classified automatically and manually, and used for creating two digital terrain models of the researched area. Further analyses determined the similarities/differences in the spatial data of Z coordinates at field points, calculated cut and fill volumes
