The Department of Geography at the University of Québec at Montréal (UQAM) utilized advanced geospatial technologies to assess the feasibility of measuring tree heights and estimating biomass with remarkable precision using satellite imagery. Through the innovative utilization of high-resolution satellite imagery from the WorldView-3 satellite, the research project successfully demonstrated the ability to measure individual tree heights and estimate biomass with unprecedented accuracy from space. This pioneering methodology, enabled by sophisticated photogrammetric algorithms and spatial analysis techniques, had significant implications for environmental monitoring, climate change research, and sustainable forest management. By leveraging geospatial technologies, the project offered a cost-effective and scalable solution for assessing forest ecosystems' health and resilience, providing valuable insights into global carbon dynamics and ecosystem services.
