In the old and now dead webpage there were some educational assets, one called “Informational Graphic” with information about how the sandbox works, does anyone have that file to share?
An informational graphic for the Shaping Watersheds Augmented Reality Sandbox. The graphic includes information about topographic maps, watersheds, and how to use the sandbox.
The Wayback Machine says the filename for the “Shaping Watersheds Augmented Reality Sandbox” publication was “Shaping-Watersheds-AR-Sandbox-Facilitation-Guide.pdf”. Searching for that filename gives a few likely results. Is this the guide you’re looking for?
