  • The use of LiDAR to identify forest transportation networks

    Creator:
    Beck, Storm J. C.
    Abstract:
    The production of high value non-conventional products, such as long utility poles; or the production of low value bulky products, such as chips or grindings; provide opportunities for forest owners to increase value from their forests. The transport of these products requires the use of specialized trucks and trailers. However,...

  • Examination of airborne discrete-return lidar in prediction and identification of unique forest attributes

    Creator:
    Wing, Brian M.
    Abstract:
    Airborne discrete-return lidar is an active remote sensing technology capable of obtaining accurate, fine-resolution three-dimensional measurements over large areas. Discrete-return lidar data produce three-dimensional object characterizations in the form of point clouds defined by precise x, y and z coordinates. The data also provide intensity values for each point that...

  • Environmental Remote Sensing with Unmanned Aircraft Systems

    Creator:
    Burnett, Jonathan D.
    Abstract:
    Small Unmanned Aircraft Systems (sUASs) equipped with optical sensors are capableof remotely sensing landscapes and wildlife at spatial and temporal resolutions that werepreviously inaccessible due to technical and budgetary limitations. Conventional remotesensing and photogrammetric workflows can be applied to the resulting high resolution imageryto facilitate new types of scientific inquiry....

  • Using Remote Sensing and Process-based Growth Modeling to Predict Forest Productivity Across Western Oregon

    Creator:
    McAdam, Erick
    Abstract:
    Accurate measurement of forest productivity is fundamental to understand the carbon balance of forested ecosystems. Recent changes in climate highlight the importance of developing methods to measure forest productivity so that sound economic and environmental decision can be made. Efforts to measure forest productivity across the landscape using remote sensing...

  • Estimating volume and value on standing timber in hybrid poplar plantations using terrestrial laser scanning : a case study

    Creator:
    Barnett, Jennifer S.
    Abstract:
    Terrestrial laser scanning (TLS) may provide a way to increase timber value recovery by replacing manual timber cruising with a simple-to-use, cost-effective alternative. TLS has been studied in several trials worldwide. Past studies have not compared TLS based estimates with mill estimates of stem value and volume. Three differently stocked...

  • Leveraging multi-sensor time series datasets to map short- and long-term forest disturbances and drivers of change in the Colombian Andes

    Creator:
    Murillo Sandoval, Paulo Jose
    Abstract:
    The spatial distribution of forest disturbance is commonly calculated using a satellite imagery-driven bi- or tri-temporal change analysis. Working in Colombia’s Cordillera de los Picachos National Natural Park – a region of consistent cloud cover and dramatic topographic relief – a change assessment with such infrequent observations cannot capture long-term...

  • 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...

  • Remote detection and predicted locations of NIPF fuel treatments in central Oregon

    Creator:
    Hall, Michael P.
    Abstract:
    Fire regimes across the western United States have been altered due to past land management and changing land use. Mitigating increased risks of wildfire occurrence in landscapes such as central Oregon requires landscape level management from both governmental and private organizations. Non-industrial private forest (NIPF) owners manage a relatively small...

  • Multi-temporal LiDAR Analysis of Landscape Fire Effects in Southwestern Oregon

    Creator:
    Hoe, Michael
    Abstract:
    Quantitative assessments of post-fire effects are key to improving our understanding of ecosystem resilience. While remote sensing technology has allowed us to assess post-fire landscape effects, we are often limited by the lack of information related to pre-fire forest attributes. As a result, our ability to interpret fire effects in...

  • Estimation and modeling of selected forest metrics with lidar and Landsat

    Creator:
    Strunk, Jacob L.
    Abstract:
    Lidar is able to provide height and cover information which can be used to estimate selected forest attributes precisely. However, for users to evaluate whether the additional cost and complication associated with using Lidar merits adoption requires that the protocol to use lidar be thoroughly described and that a basis...
