> Assuming a boat ("Looper") begins in Chicago, either take the Chicago River and Chicago Sanitary and Ship Canal, or the Cal-Sag Channel to the Des Plaines River. The waterway passes Joliet and soon becomes the Illinois River. The Illinois River travels west, through several locks, then southward, through Peoria. At Grafton, Illinois, the Illinois River joins the Mississippi River.

Of course you could start in the some Great Lake or the Erie Canal or anywhere else on the east coast.

I'm thinking that this can be a good pattern for photography portfolio sites. Voice over from photographer talking about his inspiration, walking through key memories, while letting the user browser around.

This is still wonderful.

There's a very nice effect where if you zoom in, time slows.

I have no affiliation with that site, I just enjoy it.

In a TSS, you have to drive on the right, and if you're crossing one, your heading (not your track) must be as close to 90 degrees, to minimize your exposure time. When you're sailing this can be a big pain. The anti-collision rules are altered in a TSS.

Without the the location, of course Singapore wouldn't have been able to be so important. But the location isn't everything --- Singapore manages to outperform Port Klang and Tanjung Pelepas despite the similar geographic advantages of the Malaysian ports due to much better execution.

For the fish — plenty of trawlers in the Southern Ocean.

Thailand is still dreaming of building a canal to create an alternative option.

It's not earth-shattering, but it generally makes the news ;-)

This seems unusual if you're used to ADSB tracking sites, since the line of sight goes much further due to elevation. There's also more receivers feeding them.

Very little of anything actually goes on in Greenland. It has a population of less than 57,000 and a GDP of less than $5B. The US maintains significant military presence, including airbases, missile launch and intercept capabilities, and ensures the US controls the North Atlantic, instead of Russia.

TIL the Rhine–Main–Danube Canal. Thanks

(My take would have been be to allow high sulphur fuel out on the high seas, where there's very few humans around (or flora and fauna in general). )

I don't think it's really down to super-tight security as such, rather that there's no reason to release the data publically.

Ships and airplanes broadcast data because it's useful for collision avoidance and tracking. The international maritime and aerospace system is far too complicated and large that you could ever build a private network of every ship or plane operator sharing encrypted data, or that one company could set up receivers for the tracking data worldwide. A closed system wouldn't work.

Rail is both physically and legally a finite closed space. The network operator knows definitively where every train in their network is because they have sensors in the tracks. The network is responsible for preventing collisions, not the individual trains. They have contracts with every company which operates on their tracks and if these need their internal data they can get it. So there's simply no good reason why trains should be publically broadcasting their information, or why network operators would want to expose all their internal data.

And against the no positives there are negative sides - apart from a couple of famous cases I've not heard of it in Europe, but stealing from cargo trains seems to be big business in the US: https://www.latimes.com/california/story/2022-11-17/los-ange...

In the UK the open tracking data also brought complaints from freight companies who feared competitors would use it to analyse their movements, figure out which traffic flows were the most profitable and use it for commercial advantage.
