Monitoring geometric properties of an existing forest road using airborne Lidar data
vertical profile cross section horizontal profiles total station roadbed
2018/3/6
Accurate information about geometric properties of a forest road is essential for the sustainable forestry and transportation
safety. In this study the ability of airborne Lidar in detecting vertical...
Impact of plot size and model selection on forest biomass estimation using airborne LiDAR: A case study of pine plantations in southern Spain
airborne laser scanning forest inventory regression survey design genetic selection methods
2017/4/6
We explored the usefulness of LiDAR for modelling and mapping the stand biomass of two conifer species in southern Spain. We used three different plot sizes and two statistical approaches (i.e. stepwi...
A COMPARISON OF OBJECT-BASED AND PIXEL-BASED APPROACHES TO ESTIMATE LIDAR-MEASURED FOREST CANOPY HEIGHT USING QUICKBIRD IMAGERY
Canopy height Geographic object-based image analysis
2015/11/16
Canopy surface height (CSH) is a significant forest biophysical parameter to estimate above-ground biomass and carbon content.
High- spatial resolution optical remotely sensed data have shown promis...
