ANALISIS WAKTU KERJA PENGUKURAN TINGGI POHON MENGGUNAKAN KLINOMETER DAN HAGAMETER

open access: yesULIN: Jurnal Hutan Tropis, 2018
Tree height measurement is one part of the inventory activity of standing trees before logging which requires a relatively long time and quite expensive costs, so it needs to use a more productive measuring instrument.

Examining the Role of UAV Lidar Data in Improving Tree Volume Calculation Accuracy

open access: yesRemote Sensing, 2022
Traditional forest inventories are based on field surveys of established sample plots, which involve field measurements of individual trees within a sample plot and the selection of proper allometric equations for tree volume calculation.

Can regional aerial images from orthophoto surveys produce high quality photogrammetric Canopy Height Model? A single tree approach in Western Europe

open access: yesInternational Journal of Applied Earth Observations and Geoinformation, 2020
Forest monitoring tools are needed to promote effective and data driven forest management and forest policies. Remote sensing techniques can increase the speed and the cost-efficiency of the forest monitoring as well as large scale mapping of forest ...

USE OF TREE HEIGHT FOR MANGROVE SPECIES CLASSIFICATION [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022
Mangrove forests play an important role in the balance of biodiversity. However, they are threatened by agriculture, aquaculture, urbanization and global warming.

Height function localisation on trees

open access: yesCombinatorics, Probability and Computing, 2023
AbstractWe study two models of discrete height functions, that is, models of random integer-valued functions on the vertices of a tree. First, we consider the random homomorphism model, in which neighbours must have a height difference of exactly one. The local law is uniform by definition.

Abiotic controls on macroscale variations of humid tropical forest height [PDF]

open access: yes, 2016
Spatial variation of tropical forest tree height is a key indicator of ecological processes associated with forest growth and carbon dynamics. Here we examine the macroscale variations of tree height of humid tropical forests across three continents and ...

The height of increasing trees [PDF]

open access: yesRandom Structures & Algorithms, 2008
AbstractWe extend results about heights of random trees (Devroye, JACM33 (1986) 489–498, SIAM J COMP28 (1998) 409–432). In this paper, a general split tree model is considered in which the normalized subtree sizes of nodes converge in distribution. The height of these trees is shown to be in probability asymptotic toclognfor some constantc.

Mapping Tree Height in Burkina Faso Parklands with TanDEM-X

open access: yesRemote Sensing, 2021
Mapping of tree height is of great importance for management, planning, and research related to agroforestry parklands in Africa. In this paper, we investigate the potential of spotlight-mode data from the interferometric synthetic aperture radar (InSAR)
