Terrestrial Laser Scanning for Quantifying Uncertainty in Fluvial Applications
… design (SRD) and estimating sediment loads for total maximum daily load (TMDL) development. Surveying of stream morphology traditionally involves point measurement tools, such as total stations, or remote sensing technologies, such as aerial laser scanning (ALS), which have limitations in …

Comparison of topographic information from various sources for engineering design
… meter (ppsm) and a higher resolution at 8 ppsm. Total station and real time kinematic (RTK) surveys have also been conducted and the total station data are used as the standard by which LiDAR will be evaluated. Anecdotal experiences have suggested that LiDAR data appear accurate, but overall the …

Distributed Sensing for Monitoring Cast Iron Pipe Behaviour
… Seasonal ground movements were monitored using total station and Light Detection and Ranging (LiDAR) surveying equipment. Ground movements of 23 to 30 mm were detected from a roadway repair required to fix a water main break, suggesting that both technologies are capable of detecting ground …

A comparative analysis of terrestrial laser scanning (TLS) and structure from motion (SfM) photogrammetry for measuring fluvial sediments
… provided a reliable reference of grain size. Total Station EDM theodolite provided the parent coordinate system for both SfM and meshing of TLS point-clouds. For each data set, a 0.19 m moving window (consistent with the largest sediment clast b axis) was applied to the resulting point-clouds. …
