Mapping percent canopy cover using individual tree- and area-based procedures that are based on airborne LiDAR data: Case study from an oak-hickory-pine forest in the USA
Autor: Can Vatandaslar, Taeyoon Lee, Pete Bettinger, Zennure Ucar, Jonathan Stober, Alicia Peduzzi
Publikováno v: Ecological Indicators, Vol 167, Iss , Pp 112710- (2024)
Canopy cover (CC) is the proportion of a forest floor covered by the vertical projection of tree crowns. Recently, it has become common to utilize LiDAR (light detection and ranging) canopy metrics to estimate CC over large areas. However, these metr

Evaluating the Accuracy of Remote Dendrometers in Tree Diameter Measurements at Breast Height
Autor: Zennure Ucar, Ahmet Salih Değermenci, Hayati Zengin, Pete Bettinger
Publikováno v: Croatian Journal of Forest Engineering, Vol 43, Iss 1, Pp 185-197 (2022)
An accurate tree diameter (DBH) measurement is a significant component of forest inventory. This study assessed the reliability of remote dendrometers to measure tree DBH. We compared direct caliper measurements (reference measurements) to the remote

Assessing the Accuracy of Tree Diameter Measurements Collected at a Distance
Autor: Zennure Ucar, Pete Bettinger, Krista Merry, Krisha Faw, Chris J. Cieszewski, Steven A. Weaver
Publikováno v: Croatian Journal of Forest Engineering, Vol 36, Iss 1, Pp 73-83 (2015)
The ability to measure trees remotely or at a distance may be of value to forest inventory processes. Within three forest types (young coniferous, old coniferous, and deciduous), we compared laser caliper measurements collected at distances up to 12

How a GNSS Receiver Is Held May Affect Static Horizontal Position Accuracy.
Autor: Steven A Weaver, Zennure Ucar, Pete Bettinger, Krista Merry
Publikováno v: PLoS ONE, Vol 10, Iss 4, p e0124696 (2015)
The static horizontal position accuracy of a mapping-grade GNSS receiver was tested in two forest types over two seasons, and subsequently was tested in one forest type against open sky conditions in the winter season. The main objective was to deter

ANALYSIS OF DOCUMENTATION OPPORTUNITIES OF CULTURAL HERITAGE SAMPLES WITH TERRESTRIAL PHOTOGRAMETRY METHODS
Autor: Musa Genç, Abdullah E. Akay, Ebru Bilici, Zennure Ucar
Publikováno v: Turkish Journal of Forest Science. 5:96-113
Nowadays, as in many sectors, natural and cultural resources face the danger of extinction due to misuse and consumption-oriented life in tourism. Within the framework of the sustainability tourism principle, these resources should be determined, pro

Effects of Improving Forest Road Standards on Shortening the Arrival Time of Ground-based Firefighting Teams Accessing to the Forest Fires
Autor: Zennure Ucar, Ekaterina Podolskaia, Abdullah Emin Akay
Publikováno v: Volume: 7, Issue: 1 32-38
European Journal of Forest Engineering
In fighting against forest fires, it is crucial for the ground-based firefighting team to reach a fire area in critical response time in which the chance of controlling the fires is significantly high. Road networks are the key infrastructures that p

Estimation of urban woody vegetation cover using multispectral imagery and LiDAR
Autor: Zennure Ucar, Pete Bettinger, Jacek P. Siry, Ramazan Akbulut, Krista Merry
Publikováno v: Urban Forestry & Urban Greening. 29:248-260
Urban vegetation is an important resource in built up environments, and estimation of urban canopy cover arising from trees and shrubs is an important metric in assessments of landscape quality. We used an image classification approach to estimate ur
