Alive and Dead Trees on Aerial Imagery and nDSM

This dataset includes manually delineated tree crowns, distinguishing between alive and dead trees in the Harz Mountains, for individual tree detection over three distinct years: 2009, 2016, and 2022. It features aerial imagery (RGBI), normalized Digital Surface Models (nDSM) at a 20 cm ground sampling distance (GSD), and corresponding annotations. The dataset is organized into training and testing sets.
