DESCRIPTION:Repeat lidar and photogrammetry reveal how geohazards reshape t
 errain\, but raster differencing may confuse noise with real change. In th
 is hands-on workshop\, emergency managers and analysts build robust\, unce
 rtainty-aware change detection workflows in GRASS using Hurricane Helene d
 ata.
