Rill Erosion and Drainage Development in Post-Landslide Settings Using UAV–LiDAR Data

open access: yesSoil Systems
Accurate microtopography data are an important input for characterizing small-scale rill erosion and its progression following disturbances. UAV–LiDAR systems are increasingly accessible and have successfully been used to measure microtopography data for

Development and Performance Evaluation of a Very Low-Cost UAV-Lidar System for Forestry Applications

open access: yesRemote Sensing, 2020
Accurate and repeated forest inventory data are critical to understand forest ecosystem processes and manage forest resources. In recent years, unmanned aerial vehicle (UAV)-borne light detection and ranging (lidar) systems have demonstrated ...

Context‐engineering large language models for scalable structured metadata extraction in ecological literature reviews

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Hundreds of thousands of peer‐reviewed articles and grey‐literature reports appear each year in ecology and conservation, creating a pressing need for scalable synthesis tools. We demonstrate that transformer‐based Large Language Models (LLMs), when embedded within a practical, expert‐in‐the‐loop pipeline, offer a reliable path forward ...

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

open access: yes, 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.

Design and evaluation of multispectral LiDAR for the recovery of arboreal parameters [PDF]

open access: yes, 2014
Multispectral light detection and ranging (LiDAR) has the potential to recover structural and physiological data from arboreal samples and, by extension, from forest canopies when deployed on aerial or space platforms.

A Survey of Methods for Constructing 3D Urban Models From Point Clouds

open access: yesComputer Graphics Forum, EarlyView.
The survey outlines a general process for constructing 3D models from point clouds and categorizes the methods based on their use of templates, basic surface primitives, hybrid approaches, or linear primitives. Additionally, the survey reviews the datasets and benchmarks that are essential for testing and training the developed methods.

Study of a UAV with autonomous LIDAR navigation

open access: yes, 2021
The recent growth of Unmanned Aerial Vehicles has brought them to a wide variety of industries, from construction to film production or emergency services. These vehicles still depend on some part of human intervention and can only operate comfortably in very wide and open spaces.
