Pengukuran Tinggi Pohon Menggunakan Teknologi Unmanned Aerial Vehicle (UAV) Studi Kasus di Arboretum Kwala Bekala Universitas Sumatera Utara

Abstract

This study aims to compare tree height measurements conducted in the field with those obtained from aerial photography using Unmanned Aerial Vehicle (UAV) technology at the Kwala Bekala Arboretum, University of Sumatera Utara. The research also analyzes tree height variability and the efficiency of using UAVs for tree height measurement. Data were collected through direct field observation using a hagameter and through processing aerial images with photogrammetric algorithms to produce a Digital Surface Model (DSM). The results indicate no significant difference between tree height measurements in the field with a hagameter and those obtained from aerial images with DSM, with an accuracy rate of 99.6%. Tree height variability at the Kwala Bekala Arboretum is significant, with tree heights ranging from 10 to 29 meters. The use of UAVs has proven to be efficient for measuring tree height, saving time and costs compared to conventional methods, and providing reliable data for forest management and monitoring.
