Assessment of Errors Caused by Forest Vegetation Structure in Airborne LiDAR-Derived DTMs [PDF]

open access: yesRemote Sensing, 2017
Airborne Light Detection and Ranging (LiDAR) is a survey tool with many applications in forestry and forest research. It can capture the 3D structure of vegetation and topography quickly and accurately over thousands of hectares of forest.

Analysis of the factors affecting LiDAR DTM accuracy in a steep shrub area [PDF]

open access: yesInternational Journal of Digital Earth, 2010
The creation of a quality Digital Terrain Model (DTM) is essential for representing and analyzing the Earth in a digital form. The continuous improvements in the acquisition and the potential of airborne Light Detection and Ranging (LiDAR) data are increasing the range of applications of this technique to the study of the Earth surface. The aim of this

Monitoring the Dynamics of Formby Sand Dunes Using Airborne LiDAR DTMs [PDF]

open access: yesRemote Sensing, 2021
Coastal dunes play an important role in coastal erosion risk management, where they act as a dynamic natural sea defence line. Formby coast is part of the Sefton coast in the Northwest of England and is one of the largest and most rapidly evolving sand dune systems in the UK.

A Robust Filtering Algorithm of LiDAR Data for DTM Extraction [PDF]

open access: yesProceedings of the 2nd International Conference On Systems Engineering and Modeling, 2013
For DTM extraction of road linear project from LiDAR data, this paper proposes a robust ground filtering algorithm. Firstly, a pyramidal hierarchical structure of ground candidate points is formed. Secondly, in each level, the Thin Plate Spline (TPS) surface interpolation is iteratively used to produces smooth surfaces, and based on the points ...

GENERATION OF REFERENCE VEHICLE TRAJECTORIES IN REAL-WORLD SITUATIONS USING AERIAL IMAGERY FROM A HELICOPTER [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022
Highly accurate reference vehicle trajectories are required in the automotive domain e. g. for testing mobile GNSS devices. Common methods used to determine reference trajectories are based on the same working principles as the device under test and ...
