Forests play a central role in the management of Earth’s climate. Airborne laser scanning (ALS) technologies facilitate monitoring large and impassable areas can be used to monitor 3D structure forests. While ALS-based forest measures have been studied depth, change detection forests is still subject little attention literature due challenges introduced by comparing point cloud pairs. In this s...
