International Journal of Applied Earth Observation and Geoinformation, 2014 Abstract Canopy height model (CHM) derived from LiDAR (Light Detection And Ranging) data has been commonly used to generate segments of individual tree crowns for forest inventory and sustainable management. However, branches, tree crowns, and tree clusters usually have similar shapes and overlapping sizes, which cause current individual tree crown ...

International Journal of Applied Earth Observation and Geoinformation, 2016 Abstract Individual tree crown delineation is of great importance for forest inventory and management. The increasing availability of high-resolution airborne light detection and ranging (LiDAR) data makes it possible to delineate the crown structure of individual trees and deduce their geometric properties with high accuracy.

Development of accuracy assessment tool of individual tree crown delineation
2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016Individual tree crown delineation (ITCD), which includes treetop detection and/or tree crown delineation, plays a significant role in modern forest resources management and precise forestry. Recent years, amount of ITCD algorithms have been proposed based on passive and active remotely sensed data.

Delineation of individual tree crowns for mobile laser scanning data
SPIE Proceedings, 2016The information of individual trees plays an important role in urban surveying and mapping. With the development of Light Detection and Ranging (LiDAR) technology, 3-Dimenisonal (3D) structure of trees can be generated in point clouds with high spatial resolution and accuracy.

IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020
Currently, most individual tree crowns delineation methods are proposed for aerial images and Lidar data. In this paper, a scheme is proposed to delineate tree crowns from the high spatial resolution WorldView-3 satellite imagery. We select a multiscale fitting scheme for the delineation and propose two modifications to optimize the result generated ...

Multispectral remote sensing from Unmanned Aerial Vehicle (UAV) platforms is fast becoming an economical approach to gather Very High Resolution (VHR) spatial data at the individual tree level. However, detecting and delineating tree crowns are challenging due to the intrinsic intra-class spectral variability, shadow and noise in VHR images.

Individual Tree Crown Delineation and Biomass Estimation from LiDAR Data in Gorgona Island, Colombia
IGARSS 2023 - 2023 IEEE International Geoscience and Remote Sensing Symposium, 2023Biomass estimation is a crucial component in the areas of carbon storage and forest management. Biomass can be analyzed rather at forest or at Single Tree Level (STL) and studies in both directions can be found in literature. Nevertheless, working at STL provides more accurate estimations.

Stand delineation and composition estimation using semi-automated individual tree crown analysis
Remote Sensing of Environment, 2003Abstract Stand delineation and species composition estimation are cornerstones of forest inventory mapping and key elements to forest management decision making. Improved mapping techniques are constantly being sought in terms of speed, consistency, accuracy, level of detail, and overall effectiveness.
