Plugin to compute nDSM from point clouds and compute maximal height per polygon (buildings, trees...).
LiDARHeightExtractor produces a high-quality nDSM from LiDAR point clouds and extracts per-polygon height metrics to support building analysis, canopy and forest assessment, and urban planning workflows. The plugin uses PDAL to rasterize point clouds (TIN-based), optionally filters points for DEM/DTM generation using user-provided expressions, computes nDSM = DEM − DTM with GDAL/NumPy, and writes the maximum nDSM value into a new lidar_height field on a copy of your polygon layer. Output is exported using QGIS core APIs and automatically loaded into the project; processing is logged for reproducibility and debugging.
LiDARHeightExtractor v1.0.2 - computes nDSM and adds 'lidar_height' (max per polygon). Depends on PDAL (pdal_wrench). See docs for installation instructions.
