Exercise: 3D Change Analysis at an Active Rock Glacier using Multitemporal Point Clouds

Solution using CloudCompare

Change analysis via DEM differencing

Tip: In the video we use pdal but in the new version of QGIS you can also rasterize point clouds directly.

At the end you can visualize the DEM in OGIS, which should look something like this:

Visualization of vertical change

Change analysis via DEM differencing: Vertical change between 2020 and 2021. The basemap is provided by the Web Map Service of Tyrol (https://gis.tirol.gv.at/arcgis/services/Service_Public/orthofoto/MapServer/WMSServer).
