In the previous tutorial we've merged downloaded point cloud tiles into a Virtual Point Cloud (VPC) layer. In this tutorial we're going to filter the point cloud data to derive certain features. We'll apply a filter to the classification attribute to derive the elevation points of buildings. Then we'll use expressions to derive points above a certain height. Finally, we'll try to derive vegetation points, by using a filter with the return number.
After this tutorial, you're able to:
We're going to use one LAZ tile for this tutorial. You can use, for example, tile 65DN1_07.LAZ that covers most of the center of Middelburg.
