Quick Flood Analysis with QGIS
In this video, we'll use building footprints from OpenStreetMap, a DTM and a DSM to create 2D and 3D flood maps of a city. We'll start with preprocessing the data: interpolate voids in the DTM and extrude buildings, using the DSM and zonal statistics. Next, we'll prepare flood extent layers. Finally, we'll visualize the flood extent in 3D.
