Project
In this project we present a novel method that combines a single airborne LiDAR acquisition and historical forestry maps to model the height growth, density, and wood volume of boreal forest landscapes. The goal of this project is to provide to forest managers a tool to accurately evaluate wood supply and forest growth across large remote areas affected by fires and logging.
Project
Construct digital maps using deep learning approach with the uses of remote sensing (Landsat, Sentinel, LiDAR) data.
Project
This study aims to develop a predictive tool for black spruce post-fire regeneration using stand disturbance history, and climate/site conditions. First, we want to developed a theoretical model that combined spatial variables (stand/site/climate conditions) commonly used by forest managers in eastern Canada, a fire severity index (“differenced normalized burn ratio”, or dNBR) and variables collected by in situ sampling (residual organic matter, tree age, twig severity index). Second, we will developed a spatially explicit model to predict post-fire regeneration using only spatial variables readily available in existing datasets. Our model will allow to incorporate climatic scenarios and will permit to evaluate post-fire resilience and productivity of boreal forest in a context of global change.
