  • 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...

  • 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...

  • Operator Splitting for a Wildfire Model in a Heterogeneous Environment with a Surrogate Wind Velocity Field

    Creator:
    Pantuso, Nicholas M.
    Abstract:
    Living in the Pacific Northwest, we are acutely aware of the dangers posed by wildfires. Largely due to the worsening effects of climate change, this danger is only increasing. Along with causing property and economic damage to those communities affected by wildfires, exposure to the smoke generated by wildfires can...

  • Estimating Tree Defect and Log Quality with Terrestrial Structure from Motion Photogrammetry and Handheld LiDAR

    Creator:
    Morgan, Carli J.
    Abstract:
    Forest inventories are periodic resource assessments that can estimate items such as timber volume and value, tree growth rates, carbon sequestration, forest health status, wildlife habitat, fuel loading, and more. Traditional inventories require a large investment of resources and well-trained workforce. To date, most foresters and timber cruisers inventory forests...

  • Pacific Madrone Leaf Blight Detection with Unmanned Aerial Systems and Machine Learning

    Creator:
    Barker, Matthew I.
    Abstract:
    Ground-based assessments of foliar diseases including leaf blight are time-consuming and costly. We investigated the potential for using an unmanned aerial system (UAS) in conjunction with a multispectral sensor to determine whether we could more efficiently and reliably detect and quantify leaf blight in Pacific madrones. Our methods included ground-based...

  • Deployment Planning for Multiple Marsupial Robots

    Creator:
    Lee, Chris (Yu Hsuan)
    Abstract:
    Multi-robot systems are versatile and extremely capable of exploration tasks in complex environments. Increasingly sophisticated planners, which incorporate new features of a multi-robot system, are necessary for the operation of the systems. Marsupial robots are multi-robot systems consisting of a carrier robot (e.g., a ground vehicle), which is highly capable...

  • Evaluating Methods of Aligning Real-Time GNSS Networks to the National Spatial Reference System

    Creator:
    Ohene, William
    Abstract:
    Aligning Real-Time Networks (RTNs) with the National Spatial Reference System (NSRS) is crucial to ensure accuracy, consistency, interoperability, and long-term data integrity for geospatial applications. However, the effectiveness of different alignment methods as well as the need for monitoring approaches to maintain alignment consistency with the NSRS have not yet...

  • Decentralized Multi-Robot Exploration with Sparse Communication through Deep Imitation Learning

    Creator:
    Senewiratne, Yomal K.
    Abstract:
    We present a method for decentralized, multi-robot exploration in adverse environments where communication is minimal. A key conceptual feature of our method is enabling implicit coordination between robots by training a Convolutional Neural Network (CNN) as a heuristic for planning using Monte Carlo Tree Search (MCTS). Our method consists of...

  • Effects of Subsampling Trees and Imputation Methods on the Accuracy of Height-to-Crown-Base Predictions for Douglas-fir in Southwest Oregon

    Creator:
    Allensworth, Elijah J.
    Abstract:
    Accurate estimates of height-to-crown-base (HTCB) are essential for the reliable projections of stand structure over time required for sustainable forest management. Yet, HTCB often measured alongside total height (HT) for only for a subsample of trees in traditional stand-based inventories and must be imputed for all others. We compared the...
