An insane amount of detail that you appreciate close up. Photogammetry falls apart close up.
With laser, you are talking about sub millimeter accuracy. The improvement in detail is huge.

Is the scan something you can access and explore online or is it proprietary? I was hoping there was an interactive model but I could only find short video clips.
Is the source data equally appreciably large?
Yes. IIRC, the laser scanner guy on my project estimated half a petabyte for the Titanic. It is a big ship, and doing scans in 2 dimensions at 1 knot is going to take a number of hours. It is my hope that eventually, after studies are completed and get permission by the Greek government, we start putting the entire 3D point cloud online. I'm trying to get a sample one on the NGO website.
EDIT: I've hired EIVA to do the last bit of engineering and testing as laser scanners in the past have been stationary or mounted to submarines. Voyis was the first to mount to an ROV (the VideoRay Mission Specialist Defender). Now we are doing the same with the Newton Labs PL3200UW-LW.
To get quality/sharp/accurate data, you need a stable platform. The Defender isn't very big (I'm 205, 5'10" for reference).
The IMU (inertial measurement unit - what detects the change in movement) has to be precise (the one we are using goes for $60K) and the laser must move in a smooth motion.
This is where the EIVA software comes in. You program the area, depth, and speed and you "press go." A computer will determine adjustments faster and smoother than a human.
The EIVA guys think weve got something good here, but it takes some more engineering work. Not a lot of time though.
Anyone can visit the titanic for 25 pound sterling. Bringing multi millionaire tourists to visit the wreck is just an obscene display of wealth and nothing else.

Experience the true legend of RMS Titanic, in the city where it all began. The Titanic Experience is unmissable and unforgettable, just like Titanic herself.

While I would never pay that amount of money nor assume the risk of diving to see the Titanic in person, no museum is going to be as impactful.Anyone can visit the titanic for 25 pound sterling.

That's like saying going to the zoo is the same as going on safari in Africa. Or looking at pictures of a solar eclipse is the same as seeing one in person.
Not. Even. Close. I don't harbor any resentment towards those who successfully paid their way to visit the Titanic. I think looking at it from even a small porthole would be an incredible experience.
Having had the chance to fly high enough to see the curve of the earth (military aircraft past FL500) and also flying in the far north seeing the aurora borealis effect in full strength, this is a very accurate statement. No screen how good can compare to having seen those with my own eyes.

Videos of "Titan submersible implosion" and "screams" flood social media
Despite footage claiming to include audio from the recent tragedy, the Navy has not released audio recordings of an implosion or sounds of underwater "banging."
