An Assessment of Aerial Survey Acquisition Methods for Generating Forest Inventory Models

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, […]

Investigating the patterns of vegetation-permafrost dynamics as determined by landscape-scale disturbance

The University of Maine conducts research in collaboration with Brookhaven National Laboratory and Oak Ridge National Laboratory toward a subset of science objectives outlined in the Phase 3 proposal of the Next-generation Ecosystem Experiments (NGEE) in the Arctic. The NGEE-Arctic project is using observations, experiments and modeling to improve our predictive understanding of Arctic ecosystem […]

Measurements, Models and Maps: Large-area Forest Inventory from Airborne LiDAR Data

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 […]

Xinyuan Wei

Xinyuan Wei is a PhD candidate in the School of Forest Resources.  His research is focused on (1) the impacts of wildfires on the global terrestrial biosphere carbon cycle, (2) the patterns of biome carbon fluxes in response to droughts at different time scales, (3) modeling the dissolved organic carbon flux, and (4) estimating carbon […]
