Tree heights 2018 (CHM from Lidar)

Relative vegetation height calculated from LIDAR data and DTM **Purpose**: The dataset is primarily used to determine the tree volume of the city of Zurich and for the crown covering. The height of vegetation was determined by subtracting the altitude of the terrain model (DTM) (product from the LIDAR data) from the height of the LIDAR (Light Detection and Ranging, LAS code 5:) data. Vegetation &3m) determined. A grid with 50 cm triggering was created and the highest vegetation height per cell was used. The LIDAR data from 2018 had many small gaps. Interpolated gaps & 2 m² were interpolated.
