Discovetree - An Automated Tool To Generate Stem Maps From Terrestrial Laser Scanner Point Clouds
Terrestrial laser scanning (TLS) is increasingly used in forestry to quickly and nondestructively capture a variety of tree attributes such as diameter, height, and volume. However, in order for these attributes to be measured, the individual trees must first be segmented from the point cloud. …

Quantifying structural change in UK woodland canopies with a dual-wavelength full-waveform terrestrial laser scanner
… and prepare for future climatic scenarios. Terrestrial Laser Scanning (TLS) has shown its potential to provide such measurements, offering a new approach to monitoring how forest systems change through time and space. The overall aim of this thesis was to improve the characterisation of the …

Exploration of a geometric approach for estimating snow surface roughness
… from 0.2 to 52 x 10-3m. Concurrently, a terrestrial laser scanner was used periodically to measure surface geometry and generate point clouds across the study site. Point clouds were processed and interpolated onto a regular grid for estimation of Z0 based on the geometry and distribution …

Establishment of Accuracy Testing Facilities for Terrestrial Laser Scanners
… performing at the required level of accuracy. A Terrestrial Laser Scanner is one such instrument and with the vast amount of information that this machine is able to capture, it is especially important to run regular accuracy checks. This research is building on the work that has been done by …

The Influence of Multiple Scales of Environmental Context on the Distribution and Interaction of an Invasive Seagrass and its Native Congener
… was best predicted by physical factors. Using a terrestrial laser scanner, I mapped and monitored a one hectare study site for three years. The location and shape of microtopographic features were generally stable from year to year, but the magnitude of local relief was variable. <italic>Z. …

White mica: spectrometer design, district-scale mapping, and integration of imaging spectrometer and lidar data
… back projected on to point clouds generated with terrestrial laser scanner lidar data using open-source software. The resultant 3-D data cloud was used to interpret an exposed river scarp and to place that scarp in the context of the greater Yellowstone hydrothermal system. Data generated using …
