I have used QGIS and NRW Tim Online to generate my lidar files. The lidar data works well, but there are some artifacts in the terrain after importing lidar. I attached a screenshot of the artifacts. Is this caused by the data or did i make a mistake?
I think it's something with the conversion process in qgis/gdal. Did you follow the one from the masterclass or the earlier one from the forums? The masterclass version works better for me. In the dataset with these issues I resorted to just flattening the terrain where the spikes are.
