Creating 3D models of cultural heritage sites with terrestrial laser scanning and 3D imaging
The advent of terrestrial laser-scanners made the digital preservation of cultural heritage sites an affordable technique to produce accurate and detailed 3D-computermodel representations for any kind of 3D-objects, such as buildings, infrastructure, and even entire landscapes. However, one of the …

Enhancing the Resolution and Predicting the Accuracy of Point Clouds Generated by Handheld 3D Scanners in Construction
… Nevertheless, data acquisition relying on terrestrial laser scanners or photogrammetry methods is labor-intensive during both the scanning and post-processing phases. Handheld scanners theoretically present a solution to this challenge due to their potential to significantly reduce on-site …

Evaluating the performance of multi-rotor UAV-Sfm imagery in assessing simple and complex forest structures: comparison to advanced remote sensing sensors
… to more accurate LiDAR data obtained from Aerial Laser Scanners (ALS), Terrestrial Laser Scanners (TLS), and more conventional means like manual field measurements. TH was assessed using UAVSfM and LiDAR point cloud derived DTMs, while DBH was assessed by comparing UAVSfM photogrammetric point …

Where the Ice Ends: Calving and Ice-Ocean Interactions at Helheim Glacier and Beyond
… these processes, we installed two autonomous terrestrial laser scanners (ATLAS) overlooking the terminus at Helheim Glacier, East Greenland, the first in 2015 and the second in 2018. Each laser scanner system scans every 6 hours during non-winter months and once a day during winter. Together, …
