  • Impact of Classification Algorithms on Modeling Forest Ground from Point Clouds

    Creator:
    Heine, Carver
    Abstract:
    Projects in forestry and civil engineering depend on accurate information, which is often acquired through remote sensing techniques. One of the remote sensing technologies that has gained importance in the last decade is light detection and ranging (lidar), which describes the surveyed area with 3D points, presented as point clouds....

  • Assessment of the Impact of Forest Management Activities on Forest Aesthetics Using Photogrammetric Point Clouds

    Creator:
    Begay, Bryan E.
    Abstract:
    The public concern for clearcutting in the United States in the 1970s pushed for changes in the natural resources policies. A facet of forest management that came under scrutiny was forest aesthetics. Therefore, the aim of this study is to assess the impact of harvest designs on stand aesthetics using...

  • Using Point Clouds for Single Tree Forest Inventory at the Beginning and End of the Rotation

    Creator:
    Garms, Cory G.
    Abstract:
    The portability and reduced price of unmanned aerial systems (UAS) in recent years has led to a broad range of new UAS-enabled scientific inquiries, including for forestry. Small, consumer-grade UAS are advantageous for forest measurements due to their portability, ease and safety of deployment, and notably, they are currently the...

  • Assessment of the Vegetation Changes using High-Resolution 4-Band Imagery

    Creator:
    Galapita Pallayapelage, Sudeera Wickramarathna
    Abstract:
    Natural resources are essential to humanity. With the increase in global development in recent decades, people must monitor the state of the environment, whose disturbance has a more significant impact on society than before. However, conventional environmental monitoring is challenged in highly dynamic ecosystems and large areas. As a solution,...

  • Landscape Inventory and Harvest Strategies for Individual Western Juniper in Eastern Oregon

    Creator:
    Schriver, Robert
    Abstract:
    Western juniper is a native species in eastern Oregon that became invasive during the last century since its range increased fivefold from 1936 to 1988. Western juniper’s ability to absorb rainfall and groundwater has deleterious effects on stream flow and sensitive sage grouse habitat in eastern Oregon. New methods of...

  • Unmanned aerial systems for land monitoring

    Creator:
    Strimbu, Bogdan
    Abstract:
    Data acquisition is the foundation of sound decision making. Therefore, after the work of the empiricist who laid the philosophical foundation of the data driven inference (Berkeley, 2003; Hume, 1902; Locke, 1860), significant efforts were carried in developing methods aiming at acquiring representative information for describing reality. The main instrument...

  • Individual Tree Detection and Measurement from Terrestrial Point Cloud

    Creator:
    Qi, Chu
    Abstract:
    Remote sensing forest inventory gained increased attention in the last decade triggered by the decrease in the price of sensors and the explosion of data availability and formats. Evermore, the constant advances in the hardware processing the data emphasized the necessity to develop algorithms to extract forest relevant information from...

  • Estimation of surface canopy water in Pacific Northwest forests by fusing radar, lidar, and climatic data

    Creator:
    Heffernan, Scott A.
    Abstract:
    Surface Canopy Water (SCW) is the intercepted rain water that resides within the tree canopy and plays a significant role in the hydrological cycle. Challenges arise in measuring SCW in remote areas using traditional ground based techniques. Remote sensing in the radio spectrum has the potential to overcome the challenges...

  • Estimation of Soil Particle Size Distribution using CT Scans

    Creator:
    Boath, Max E.
    Abstract:
    Remote sensing techniques have been applied extensively in geospatial investigations, but their use in measuring soil physical attributes has been far less explored. Soil particle size distributions (PSD) are indispensable in modeling pedological and hydrological processes as well as biodiversity. However, estimation of PSD via gravimetric measurement methods, the standard...

  • Measuring and Modeling the Structure of Coniferous Trees with Point Clouds Data

    Creator:
    Fang, Rong
    Abstract:
    Coniferous trees are a major North American crop that has been intensively managed for its commercial value, while also serving as critical habitat for abundant wildlife and as carbon sinks. Having diverse functions, North American temperate coniferous forests have become a research hotspot for numerous scientific studies aiming to integrate...
