Great Lakes Depth Maps

thingiverse

These are 1:25,000 scale depth maps in reverse of the Great Lakes (Minus Superior as the dataset is lacking) made from publicly available data accessed via https://www.ngdc.noaa.gov/mgg/greatlakes/. I utilized my own python script to convert csv data into stl format and then refined the files in Blender and Meshlab for accurate scaling. By depth maps in reverse, I mean that the model's height is proportional to the lake's depth at that point. It's as if the depth profile was reflected across the surface of the lake. (I'm aware Cura offers a mirroring option available if anyone wants to print an actual depth profile for these models; just mirror across the flat base.) There may be some small features that won't print well on standalone lake models but could be better represented by the models with bases. I've successfully printed the Lake Michigan model with the base out of nylon (This left many strings). I suspect PLA might be a more suitable material for printing with.
