The Deciduous Tree Crown Segmentation Challenge

Deciduous tree crown segmentation is widely recognized as a particularly challenging task. While various approaches for conifer crown delineation have proven successful, their transferability to deciduous forest stands remains limited. Accurate crown segmentation constitutes a critical prerequisite for assessing the vitality of individual deciduous trees based on spectral or structural metrics. In particular, in dense deciduous stands characterized by...

Leaf-Off Flight Campaign in Park3D in`26

In march 2026, we began acquiring leaf-off data over all SPSG park areas in Potsdam as part of the Park3D project. This effort was primarily motivated by the improved potential for precise tree crown segmentation under leaf-off conditions. A key challenge in deciduous tree crown segmentation is that it is often not possible to directly verify whether a segmented crown...

FSU Jena wins the SPSG Park3D Project! Updated

First L2 LiDAR data capture over Park Sanssouci – (2025-07-20) Priority was on detailed and dense vegetation point clouds. The L2 was used in 120m AGL with 240khz capture rate and 5-returns activated and 70% track overlap at 8m/s speed. We generated a 2.4billion point cloud description. The following animation is from a downsampled version of only 500 mio points....
