Influence of Waveform Characteristics on LiDAR Ranging Accuracy and Precision [PDF]

Sensors, 2018
Time of flight (TOF) based light detection and ranging (LiDAR) is a technology for calculating distance between start/stop signals of time of flight. In lab-built LiDAR, two ranging systems for measuring flying time between start/stop signals include time-to-digital converter (TDC) that counts time between trigger signals and analog-to-digital ...

Significant Decline in Carbon Storage at the Edges of Mangrove Forest

Earth's Future, Volume 14, Issue 9, September 2026.
Abstract Quantitative analysis of blue carbon stored in mangrove ecosystems is essential for understanding their role in climate change mitigation. However, the impacts of edge effects in fragmented mangrove forests are often overlooked in large‐scale blue carbon assessments.

Submarine Landslides Could Cause Wide‐Spread Tsunami Impact in the East Sea (Sea of Japan)

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract The East Sea (Sea of Japan) is a seismically active back‐arc basin with a history of devastating tsunamis, yet regional hazard assessments and mitigation planning often overlook the tsunamigenic potential of submarine landslides. This study investigates the tsunami impact of large‐scale mass failures along the southwest (SW) margin of the East

IMPROVEMENTS IN LIDAR BATHYMETRY DATA ANALYSIS [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019
Airborne Lidar Bathymetry is a laser scanning technique to measure waterbody bottom topography in shallow waterbodies with limited turbidity. The topic has recently gained relevance due to the advent of new sensor technologies allowing for much higher ...

Functional traits explain responses of Appalachian birds to vertical and horizontal forest structure

Journal of Animal Ecology, Volume 95, Issue 9, Page 1598-1615, September 2026.
The study of bird–forest relationships dates back decades, but rarely have the relationships of functional traits to 3D forest structure responses been considered for dozens of species at regional scales. Abstract Species interact with habitat based on their functional traits, but it is unclear how specific traits interact with the multiple components ...

Tracking and modelling native woodland expansion in the Scottish Highlands using LiDAR

Journal of Applied Ecology, Volume 63, Issue 9, September 2026.
Forest restoration projects should utilise the new LiDAR‐based pipelines to effectively map young trees, assess whether targets are met, and plan further action. Notably, the Scottish Government is now commissioning a national airborne LiDAR scan, providing a unique opportunity to upscale our algorithms to create national woodland expansion databases ...

Intercomparison of Water Vapor Data Measured with Lidar during IHOP_2002. Part II: Airborne-to-Airborne Systems [PDF]

, 2007
The dataset of the International H2O Project (IHOP_2002) gives the first opportunity for direct intercomparisons of airborne water vapor lidar systems and allows very important conclusions to be drawn for future field campaigns.

Airborne UV Lidar for Forest Parameter Retrievals

EPJ Web of Conferences, 2016
A full-waveform UV lidar performed airborne measurements over several temperate and tropical forests sites. The structural and ecological parameters (canopy height, quadratic mean canopy height and apparent foliage) were extracted from lidar ...
