I worked with the raster cells issued from Iber (flow depth distribution every 10 s, cell size 5 m), some OSM layers, and sentinel-2(L1C) data. Much of the work was done with GRASS, a pinch of sqlite, some bash scripted operations on the huge series of images, and big chunks of blender to produce a realistic view.
