Da nuvola di punti a DTM in QGIS

Creating a DEM from a point cloud using QGIS. This is the topic of this video. And if the cloud points you're processing refer to the terrain, then you can create a DTM (Digital Terrain Model) and contour lines. Once upon a time, all the tools in the "LAStools" suite for QGIS were available and free. Now things have changed a bit: some are still available, but most of the tools are licensed. But QGIS has some built-in tools that allow you to process point clouds (even just a little). My advice is to work with lightweight data, subsampled point clouds, within QGIS, because it's definitely not the best software for managing heavy, dense 3D data. Here, I work with both a LAS file and points organized in a text file. This video is part of the "QGIS in Action" project, conducted in close collaboration with @GterGeomatica. I host the project and try to showcase their extensive QGIS expertise, which they generously share.
