Interpreting a Legacy Fossil Assemblage Excavated From Waribruk (New Guinea II Cave), GunaiKurnai Aboriginal Country, Snowy River National Park, Southeastern Australia

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT In this paper we report on faunal remains recovered from a legacy archaeological excavation undertaken in the rockshelter entrance of Waribruk (New Guinea II Cave), a GunaiKurnai site located on the west bank of the Snowy River, East Gippsland, southeastern Australia.

Forest Canopy Height Estimation from Calipso Lidar Measurement [PDF]

open access: yesEPJ Web of Conferences, 2016
The canopy height is an important parameter in aboveground biomass estimation. Lidar remote sensing from airborne or satellite platforms, has a unique capability for forestry applications. This study introduces an innovative concept to estimate canopy height using CALIOP two wavelengths lidar measurements.

Estimation of canopy structure and individual trees from laser scanning data [PDF]

open access: yes, 2012
During the last fifteen years, laser scanning has emerged as a data source for forest inventory. Airborne laser scanning (ALS) provides 3D data, which may be used in an automated analysis chain to estimate vegetation properties for large areas ...

Correction of Terrain Effects on Forest Canopy Height Estimation Using ICESat-2 and High Spatial Resolution Images [PDF]

open access: yes, 2022
The Ice, Cloud, and Land Elevation Satellite–2 (ICESat–2) carries the Advanced Topographic Laser Altimeter System (ATLAS), enabling global canopy height measurements from forest canopy height models (CHMs). Topographic slope is a crucial factor affecting

Prospecting of Architectural Features Using LiDAR‐UAV Technology, Deep Neural Networks and Visualization Techniques: A Case Study in Kuélap and Cambolín (NW Peru)

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT High‐resolution and accurate synoptic images of terrestrial topography, even in densely forested areas, have proven valuable for archaeology by enabling the identification and characterization of relief patterns associated with ancient human activities. This study presents a novel approach that integrates digital terrain models (DTMs) obtained

Repeat airborne laser scanning to assess canopy height changes in tropical montane forests [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Tropical montane forests are vital ecosystems globally, preserving biodiversity, carbon stocks, and capturing moisture. We employed two airborne laser scanning (ALS) data sets to study changes in montane forest canopy heights in the Taita Hills, Kenya ...

Estimates of forest canopy height and aboveground biomass using ICESat [PDF]

open access: yesGeophysical Research Letters, 2005
Exchange of carbon between forests and the atmosphere is a vital component of the global carbon cycle. Satellite laser altimetry has a unique capability for estimating forest canopy height, which has a direct and increasingly well understood relationship to aboveground carbon storage.

Biomass estimation as a function of vertical forest structure and forest height: potential and limitations for radar remote sensing [PDF]

open access: yes, 2010
One common method to estimate biomass is measuring forest height and applying allometric equations to get forest biomass. Conditions like changing forest density or changing forest structure bias the allometric relations or biomass estimation fails ...

A Century of Learning: The Story of ESA's Education Committee, 1918–2025

open access: yesThe Bulletin of the Ecological Society of America, EarlyView.
Abstract The Education Committee and its precursors have been highly influential within the Ecological Society of America. Here we document the Education Committee's history, from its origins in reviewing curricular materials through major contributions to ecological literacy, teaching innovation, diversity initiatives, and professional development ...

Scale dependency of lidar‐derived forest structural diversity

open access: yesMethods in Ecology and Evolution, 2023
Lidar‐derived forest structural diversity (FSD) metrics—including measures of forest canopy height, vegetation arrangement, canopy cover (CC), structural complexity and leaf area and density—are increasingly used to describe forest structural ...
