Direct and automatic measurements of stem curve and volume using a high-resolution airborne laser scanning system

Science of Remote Sensing, 2022
Today, high-quality reference tree measurements, including the position, diameter, height and volume, are cumbersome and slow to carry out, but highly needed for forest inventories based on airborne laser scanning. Mobile laser scanning technologies hold

Large scale mapping of forest attributes using heterogeneous sets of airborne laser scanning and National Forest Inventory data

Forest Ecosystems, 2021
Background The Norwegian forest resource map (SR16) maps forest attributes by combining national forest inventory (NFI), airborne laser scanning (ALS) and other remotely sensed data. While the ALS data were acquired over a time interval of 10 years using
