Evacuation route selection based on tree-based hazards using LiDar and GIS

Laefer, Debra F. ; Pradhan, Anu (American Society of Civil Engineering (ASCE), 2006-04)

Falling trees pose a great hazard to the safe and uninterrupted use of the road transportation system, during storm events. The present process of manually identifying potentially hazardous trees is laborious and inefficient. ...
Flight optimization algorithms for aerial LiDAR capture for urban infrastructure model generation

Hinks, Tommy ; Carr, Hamish ; Laefer, Debra F. (American Society of Civil Engineering (ASCE), 2009-11)

Aerial Light Detection and Ranging (LiDAR) offers the potential to auto-generate detailed, three-dimensional (3D) models of the built environment in urban settings. Auto-generation is needed as manual generation is not ...
New possibilities for damage prediction from tunnel subsidence using aerial LiDAR data

Laefer, Debra F. ; Hinks, Tommy ; Carr, Hamish (2010-06)

Computation modelling has not been fully exploited for predicting building damage due to tunnel-induced subsidence, because of the expense and time required to create computational meshes for the vast quantity of buildings ...
Processing of terrestrial laser scanning point cloud data for computational modelling of building facades

Laefer, Debra F. ; Truong Hong, Linh ; Fitzgerald, Michael (Bentham Science, 2011-01)

With the rapidly increasing availability of laser scanning data and the growing pressure to use it as the basis for computational models, there has been heighten interest in quickly, cost-effectively, and accurately ...
Storage, manipulation, and visualization of LiDAR data

Schön, Bianca ; Bertolotto, Michela ; Laefer, Debra F. ; Morrish, Sean (International Society of Photogrammetry and Remote Sensing, 2009-02)

In recent years, three-dimensional (3D) data has become increasingly available, in part as a result of significant technological progresses in Light Detection and Ranging (LiDAR). LiDAR provides longitude and latitude ...
Viability assessment of terrestrial LiDAR for retaining wall monitoring

Laefer, Debra F. ; Lennon, Donal (American Society of Civil Engineering (ASCE), 2008-03)

The decreased cost and increased processing speed for terrestrial laser scanners have made this remote sensing procedure much more attractive. The approach has two major advantages over traditional surveying: (1) a ...
