Orthographic Overlays

Full Screen

Using an orthographic projection to overlay the Mare Island Strait and San Pablo Bay (drawn in magenta) with various water bodies around the world (drawn in cyan). The two maps are drawn with the “multiply” blend mode, so overlapping water areas become blue.

Best viewed in a full browser window (click the “Open” text) so you can scroll down and see more overlays.

Also note that it might take a long time to load.
