Airborne Hyperspectral Data Application in Health Stress Detection of Blueberry Fields and Ash Trees
Advanced detection of health stress in agricultural fields and forests can prompt management responses to mitigate detrimental conditions such as nutrient deficiencies, disease, and mortality. New applications in hyperspectral data and imaging spectroscopy on agriculture and forests have shown the potential for early stress detection. We build on previous work by assessing two different systems; […]
Over the past 25 years, the average annual temperature in Maine increased by nearly 2 °C and is predicted to continue rising if global carbon emissions are not reduced. Climate warming is affecting the social and ecological systems of the northeastern U.S., including changes in the seasonal timing and duration of biophysical processes. Phenology is […]
Wheatland Lab members Xinyuan Wei & Dan Hayes contributed to the newly released State of Maine Carbon Budget.
Structure from motion (SfM) derived three dimensional (3D) point clouds have performed well in comparison to airborne laser scanning (ALS) in generating timber inventory models, yet little has been done to assess the viability of a wide range of aerial image acquisition methods for developing these models. Remote sensing factors such as sensor reflectance characteristics, […]
Dave is responsible for the coordination, planning, and implementation of aerial survey flight missions and image processing workflows. He supports the technical instruction of geospatial and remote sensing applications to SFR graduate and undergraduate students, forest industry professionals, small woodland owners, and various government and non-profit entities. Dave brings his extensive aviation experience to the […]
Tony provides remote sensing and geospatial training to stakeholders in Maine’s forest sector, including industry professionals, small woodland owners, and conservation partners. He supports geospatial science teaching and research efforts in the School of Forest Resources at UMaine, and is responsible for outreach and coordination with various stakeholders throughout the state. Tony is a founding […]
The Wheatland Lab will be giving our year one project update for our CFRU project entitled “Measurements, Models and Maps: Large-area Forest Inventory from Airborne LiDAR Data” during the 2020 winter advisory meeting.
This project has organized and carried out initial investigations into the use of LiDAR remote sensing analysis to enhance the design and operation of inventory programs for Maine’s forest industry stakeholders. The research conducted here is evaluating ground-based inventory plot designs together with existing, publicly-available Airborne Laser Scanning (ALS) data sets processed in a high […]
