Laserscanning and Multi-Spectral Imaging from UAV for Evaluating the Condition of Vegetation
Classifying forests with satellite images and airborne images combined with data from laserscanning is nothing new. Due to the fast development in unmanned aircrafts in the last years, there are new opportunities for evaluating the condition of vegetation. Surveying flights are much cheaper with UAVs and can be repeated more often than with satellites. The low cruising altitude of UAVs enables to take images with very high resolution and laserscans with high point density. This fact offers the possibility to work on a single tree base. The separation of conifers and deciduous trees will be more accurate and the recognition of standing deadwood will be more precise. These and more opportunities will be shown in this presentation.
