A Comparison of Tree Segmentation Methods for Savanna Tree Extraction from TLS Point Clouds

aus: Land
Detecting trees accurately from terrestrial laser scanning (TLS) point clouds is crucial for processing terrestrial LiDAR data in individual tree analyses. Due to the heterogeneity of savanna ecosystems, our understanding of how various segmentation methods perform on savanna trees remains limited. Therefore,…

Quantifying Tree Structural Change in an African Savanna by Utilizing Multi-Temporal TLS Data

Structural changes in savanna trees vary spatially and temporally because of both biotic and abiotic drivers, as well as the complex interactions between them. Given this complexity, it is essential to monitor and quantify woody structural changes in savannas efficiently. We implemented a non-destructive…

Terrestrial Laser Scanning (TLS) in South African ecosystems

Savannas are heterogeneous ecosystems comprising a mix of woody vegetation and grasses. Most field-based inventory and remote sensing techniques are limited in accounting for lower stratum vegetation structure. Terrestrial Laser Scanning (TLS) offers a method for retrieving data for holistic Above-Ground…

Individual Tree-Scale Aboveground Biomass Estimation of Woody Vegetation in a Semi-Arid Savanna Using 3D Data

Allometric equations are the most common way of assessing Aboveground biomass (AGB) but few exist for savanna ecosystems. The need for the accurate estimation of AGB has triggered an increase in the amount of research towards the 3D quantification of tree architecture through Terrestrial Laser Scanning…
