Fly-through movies

These movies were created in Fledermaus with a 2 m grid, 3x vertical exaggeration and a Sun azimuth of 240 degrees. They simulate a fly-through of areas of the sea floor of the mouth of San Francisco Bay.

FILE SIZE WARNING: File sizes are quite large, and will take several minutes to hours to download (depending on your internet connection).

17 MB: Fly_Through1.mpg: This movie flies you from Alcatraz and under the Golden Gate, and over the sand waves and down to Ocean Beach.
11 MB: Fly_Through2.mpg: This movie zooms out from the center of the large sand wave field into space.
17 MB: Fly_Through3.mpg: This movie flies toward the mouth of San Francisco Bay and then takes a tour of the coastline between Baker Beach and Ocean Beach.
11 MB: Fly_Through4.mpg: This movie zooms out from a dense sand wave field on the San Francisco Bar then flies into and zooms in on the giant sand wave field.
15 MB: Fly_Through5.mpg: This move flies toward the Golden Gate then circles around the inlet mouth and takes a tour of Ocean Beach.
