Using Unoccupied Aerial Systems and Structure-from-Motion to Measure Forest Canopy Cover and Individual Tree Height Metrics in Northern California Forests - 2025-03-24 - Research Publication - eBee X flights with a RedEdge-MX multispectral camera used 75% overlap at up to 122 metres, producing 8-centimetre imagery and SfM point clouds averaging 180 points per square metre. Across 44 plots, UAS canopy cover… - source: doi.org
Gully Extraction and Mapping in Kajoo-Gargaroo Watershed – Comparative Evaluation of DEM-Based and Image-Based Machine Learning Algorithm - 2023-01-13 - Research Publication - Thirty-four eBee X flight sorties collected Aeria X imagery at roughly 6-centimetre ground sampling distance with 80% forward and 60% side overlap. The imagery was processed into an orthophoto and terrain model, then used… - source: doi.org
Evaluating the Impacts of Flying Height and Forward Overlap on Tree Height Estimates Using Unmanned Aerial Systems - 2022-09-11 - Research Publication - Four forest sites were flown with an eBee X at 80, 100 and 120 metres and at 80%, 85%, 90% and 95% forward overlap, producing SfM point clouds for all parameter combinations. Top-of-canopy-height RMSE ranges from 1.75 to… - source: doi.org
