Geomorphometry Coffee Talk on YouTube: “Geomorphometry with GRASS” by Corey White.

DEM fusion tools, terrain uncertainty modeling, and overland flow simulation. Also a good look at how GRASS plugs into reproducible terrain workflows via Python and Jupyter, plus the open addon ecosystem for sharing methods.

[I used to shore dive in the Straits Of Juan de Fucca, Washington State side, and Crescent Lake - so I chose that area as a CoNED example to explore; good memories, including of the 18 Wheeler Burger with pie & coffee in Joyce, WA on drizzly days]
