If this is interesting to you, you should definitely check out the Bay Model (<a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;U.S._Army_Corps_of_Engineers_Bay_Model" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;U.S._Army_Corps_of_Engineers_B...</a>). Its a scale model of the SF Bay and the Delta in Sausalito that was built by the Army Corps of Engineers. Its admission free!

Wow. USGS has a store with this poster: <a href="https:&#x2F;&#x2F;store.usgs.gov&#x2F;b2c_usgs&#x2F;catalog&#x2F;setCurrentItem&#x2F;(isQuery=yes&amp;xcm=r3standardpitrex_prd&amp;query=*golden+gate+under*&amp;layout=6_1_61_58&amp;uiarea=2&amp;ctype=areaDetails&amp;next=seeItem&amp;carea=%24ROOT&amp;citem=00000001550000000030)&#x2F;.do" rel="nofollow">https:&#x2F;&#x2F;store.usgs.gov&#x2F;b2c_usgs&#x2F;catalog&#x2F;setCurrentItem&#x2F;(isQu...</a><p>In case that brutal link doesn&#x27;t work: go to <a href="https:&#x2F;&#x2F;store.usgs.gov&#x2F;" rel="nofollow">https:&#x2F;&#x2F;store.usgs.gov&#x2F;</a> and search for &quot;Under the Golden Gate Bridge&quot;.<p>The poster is basically 1M^2 so is a decent size.<p>EDIT: Not 1M^3, but 1M^2. We&#x27;ll have to wait for the 1M^3 version...

&gt;<i>The water depths have a 4x vertical exaggeration while the land areas have a 2x vertical exaggeration.</i><p>Can someone clarify what this means?

So, there is a rock jutting up just inside the bay from the gate, right out of the tidal channel to what looks like 40-60 feet. That is PERFECT for king salmon fishing I&#x27;m betting. Usually I go outside the gate, but right there as the tide comes in? Probably filled with fish.<p>Only problem is it is right in the sea lanes!

Gorgeous. Anyone have any tips on printing this in high quality?

I have found some more information in 2010. <a href="http:&#x2F;&#x2F;ww2.kqed.org&#x2F;quest&#x2F;2010&#x2F;10&#x2F;14&#x2F;sand-waves-and-the-golden-gate&#x2F;" rel="nofollow">http:&#x2F;&#x2F;ww2.kqed.org&#x2F;quest&#x2F;2010&#x2F;10&#x2F;14&#x2F;sand-waves-and-the-gold...</a>

It says &#x27;meter scale&#x27;. I would think accounting for tidal heights with gps and other sensors, silt drift while scanning, they would be getting &#x27;half-meter&#x27; minimum. I am not a geophysical studen...just thought they would get better resolution.

Anyone knows what 3D visualization software may have been used to generated these views?

well i guess the idea i had for creating wall to retain elevating water out of the bay is never going to work now.<p>RIP inland bay area real estate when the water levels raise. :(
