Rockfall detection from terrestrial LiDAR point clouds: A clustering approach using R
In this studywe analyzed a series of terrestrial LiDAR point clouds acquired over a cliff in Puigcercos (Catalonia, Spain). The objective was to detect and extract individual rockfall events that occurred during a time span of six months and to investigate their spatial distribution. To this end local and global cluster algorithms were applied. First we used the nearest neighbor clutter removal...
متن کاملAssessing Geometry of Rock Masses using Static and Mobile LiDAR Scanning
Transportation corridor management is regularly performed for evaluation of road conditions, hazards, and planning, and is traditionally based on the manual inspection of the corridors. Recent research projects have evaluated advanced remote sensing technologies, such as LiDAR and photogrammetry, to replace preliminary field evaluations with desktop studies through evaluation of 3d sensor data....
متن کاملSynthesis of Transportation Applications of Mobile LIDAR
A thorough review of available literature was conducted to inform of advancements in mobile LIDAR technology, techniques, and current and emerging applications in transportation. The literature review touches briefly on the basics of LIDAR technology followed by a more in depth description of current mobile LIDAR trends, including system components and software. An overview of existing quality ...
متن کاملInSAR Monitoring of Landslides affecting strategic Transportation Corridors
In this paper, we present the results of several case studies using InSAR techniques from high resolution RADARSAT to monitor active landslides triggered by earthquakes and other geomorphic processes. Our results have shown that our InSAR results were used that facilitate mitigation efforts along strategic transportation and energy corridors as well as reconstruction efforts in earthquake damag...
متن کاملThe Application of Terrestrial Laser Scanning for Monitoring Natural Hazards
Terrestrial laser scanning is used as a helpful observation method in hazard assessment to collect 3D data from changing landscape surfaces, to obtain information about the current states of natural hazard processes. Three different applications of terrestrial laser scanning for monitoring natural hazard are presented to better understand the method of application, based on the outcome of previ...
