  • 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...

  • 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...

  • Classification strategies for unbalanced binary maps : finding Ponderosa pine in the Willamette Valley

    Creator:
    Riddell, Audrey P.
    Abstract:
    Forest species classifications are becoming increasingly automated as advances are made in machine learning. The algorithms used to identify tree species range from simple decision trees to intricate neural networks, and often excel in accurately delineating tree species. However, complex algorithms can have high input costs, including the cost of...

  • 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...
