I have recently tinkering with lidar point cloud storage in Manifold Future and from what I have seen so far want to congratulate Manifold engineering on the incredible achievement that is the Radian Map format.

Out of idle curiosity, I have imported ever larger lidar pointclouds into MAP storage with a view to assessing whether Radian technology offers a potential solution to our ongoing problem we have with lidar storage, discovery and analysis.

Encouraged by my findings, I now have our organization's entire point cloud dataset and all las attribution stored as a single table containing some 1.72 billion points. Once imported, I have been absolutely astonished by the performance opening the map file which as shown in the screen grab below is ~0.4 of a second! Considering that following this blink of an eye, all of the data is available in a parallel data structure and ready to go with Radian's parallel analytics, this represents a huge achievement and opens up a host of possibilities.

How many records is 1.72 billion? I had no real comprehension, but at the height an individual record shows in attached the screen grab, if I were to scroll through the entire table, I'd be at it a while as it would be 6820 kilometers long!

Sorry, I meant 8620km long even more astonishing

So, 1.35 times the radius of the Earth.

Everything really is a table.

Yes but did the first table come from nothing or did it have no beginning

...since the beginning of everything is traditionally the word, the first table came from SQL.

(And now I see what was up with the desires to have bottomless tables.)

It seems logic (SQL) comes must come from illogic (the beginning), so I suppose illogical requests will continue
