World Map with bathymetry

thingiverse

This is a topographical map featuring included bathymetry, underwater landscape details. I obtained the data from NASA's Visible Earth website: https://visibleearth.nasa.gov/view.php?id=73963 and https://visibleearth.nasa.gov/view.php?id=73934. To visualize this information, I reduced the number of points to 2%, then used openScad to superimpose them on top of each other. The resulting design features a dramatic underwater terrain. difference(){ scale([0.6, 0.6, 0.1]) surface(file = "gebco_08_rev_bath_2.png", center = true); color("blue", 1.0) cube(size =[300, 300, 3], center=true); } translate([0, 0, 9.5]) difference(){ scale([0.6, 0.6, 0.1]) surface(file = "gebco_08_rev_elev_2.png", center = true); color("blue", 1.0) cube(size =[300, 300, .3], center=true); }
