It’s so much fun and actually has lots of practical applications for map-minded folks like us. Also, if you use GEBCO data, be sure to cite it. Sneaky! Extra credit: use this wave pattern in your glass walls.Ģ2:22 Dropping in some manual labels to annotate the depth markers and three pools of Challenger Deep.Ģ7:00 Sneaking in some silly little sparkle graphics to make it look like glistening airbrushed art from the 80s!Ģ8:00 Shoot, now it’s time for a title. Like a block diagram, really.ġ2:25 Drawing a surface and giving it an image fill of waves. And hillshade! Which is merged into the bathymetry with the “overlay” blend mode!Ĥ:22 Creating depth references with polygon map notes, and applying a custom (negative) elevation offset to each instance.Ĩ:50 Time for a layout! Get the perspective the way you like it because once we start drawing graphics we are locked in.ĩ:31 Manually drawing dirt curtains along the edge of the scene, to hack a geological cube.

I chose 5x.ģ:34 Giving this bathymetry a nice blue gradient. If you are curious about how to make a not-bathymetric version of one of these, have a look here.Ġ:00 Standard fare intro, with my face mercifully covered for much of it.Ġ:19 Unabashed The Sound of Music reference introducing GEBCO bathymetric data, and how to download an extract.ġ:50 Adding bathymetry image to a local scene AND as its elevation surface.Ģ:55 Vertical exaggeration to taste. If you are curious about how long it would take to freefall this distance, or what the pressure might do to you, then have a look at this StoryMap. It is a 5x vertically-exaggerated cube extract of the deepest part of the ocean floor.
