Automated quantification of distributed landslide movement using circular tree trunks extracted from terrestrial laser scan data

Creator:: Conner, Jeremy C. and Olsen, Michael J.
Abstract:: This manuscript presents a novel algorithm to automatically detect landslide movement in a forested area using displacements of tree trunks distributed across the landslide surveyed repeatedly using terrestrial laser scanning (TLS). Common landslide monitoring techniques include: inclinometers, global position system (GPS), and interferometric synthetic aperture radar (InSAR). While these techniques...

Hinged, pseudo-grid triangulation method for long, near-linear cliff analyses

Creator:: Olsen, Michael J., Kuester, Falko, and Johnstone, Elizabeth
Abstract:: LIDAR scanners can rapidly collect high resolution, cm-level accurate point clouds representing topography, suitable for change detection if scans are repeated over time. To perform meaningful volumetric change analyses, point clouds are commonly triangulated to produce continuous, digital terrain models (DTMs). However, DTM creation methods generally require a fixed look...

Historical Sources of Science-as-Social-Practice: Michael Polanyi's Berlin

Creator:: Nye, Mary Jo
Abstract:: Historians and sociologists of science often identify the efflorescence of social stud ies of science with the work of postwar American intellectuals such as Robert K. Merton and Thomas S. Kuhn. They often also refer to the views of Michael Polanyi (1891-1976) on the roles of tacit knowledge, apprenticeship, social...

Synthesis of Transportation Applications of Mobile LIDAR

Creator:: Williams, Keith, Olsen, Michael J., Roe, Gene V., and Glennie, Craig
Abstract:: 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...

TopCAT – Topographical Compartment Analysis Tool to analyze seacliff and beach change in GIS

Creator:: Olsen, Michael J., Young, Adam P., and Ashford, Scott A.
Abstract:: This paper discusses the development of a new GIS extension named the Topographic Compartment Analysis Tool (TopCAT), which compares sequential digital elevation models (DEMs) and provides a quantitative and statistical analysis of the alongshore topographical change. TopCAT was specifically designed for the morphological analysis of seacliffs and beaches but may...

A Review of LIDAR Radiometric Processing: From Ad Hoc Intensity Correction to Rigorous Radiometric Calibration

Creator:: Kashani, Alireza G., Olsen, Michael J., Parrish, Christopher E., and Wilson, Nicholas
Abstract:: In addition to precise 3D coordinates, most light detection and ranging (LIDAR) systems also record “intensity”, loosely defined as the strength of the backscattered echo for each measured point. To date, LIDAR intensity data have proven beneficial in a wide range of applications because they are related to surface parameters,...

Individual snag detection using neighborhood attribute filtered airborne lidar data

Creator:: Wing, Brian M., Ritchie, Martin W., Boston, Kevin, Cohen, Warren B., and Olsen, Michael J.
Abstract:: The ability to estimate and monitor standing dead trees (snags) has been difficult due to their irregular and sparse distribution, often requiring intensive sampling methods to obtain statistically significant estimates. This study presents a new method for estimating and monitoring snags using neighborhood attribute filtered airborne discrete-return lidar data. The...

Designing a citizen involvement program : a guidebook for involving citizens in the resolution of environmental issues

Creator:: Howell, Robert E., Olsen, Marvin Elliott, and Olsen, Darryll
Abstract:: Designing A Citizen Involvement Program presents a model and supportive materials that can be used to design and implement a program for involving citizens in decision-making that concerns significant environmental issues. These actions might be large-scale construction projects, such as building a dam, an electric power plant, or a nuclear...

Microsatellites Reveal Population Identity of Individual Pink Salmon to Allow Supportive Breeding of a Population at Risk of Extinction

Creator:: Olsen, Jeffrey B., Bentzen, Paul, Banks, Michael A., Shaklee, James B., and Young, Sewall
Abstract:: Efforts to restore depressed populations of Pacific salmon Oncorhynchus spp. are often hampered by the inability to assign population identity to individuals in an admixture. This knowledge is of particular concern in supportive breeding programs, in which misidentification of individuals to population may result in progeny of mixed heritage, which,...

To Fill or Not to Fill: Sensitivity Analysis of the Influence of Resolution and Hole Filling on Point Cloud Surface Modeling and Individual Rockfall Event Detection

Creator:: Olsen, Michael J., Wartman, Joseph, McAlister, Martha, Mahmoudabadi, Hamid, O'Banion, Matt S., Dunham, Lisa, and Cunningham, Keith
Abstract:: Monitoring unstable slopes with terrestrial laser scanning (TLS) has been proven effective. However, end users still struggle immensely with the efficient processing, analysis, and interpretation of the massive and complex TLS datasets. Two recent advances described in this paper now improve the ability to work with TLS data acquired on...
