Altered Maps XVIII: Continuing Curious Cartography

[Samson]

M2 tidal constituent. Red is most extreme (highest highs, lowest lows), with blues being least extreme. White cotidal lines converge in blue areas indicating little or no tide. Around these convergences, called amphidromic points, curved arrows show the direction of the tides, each indicating a synchronized 6-hour period. Tidal ranges generally increase with increasing distance from amphidromic points. Tide waves move around these points, generally counterclockwise in the N. Hemisphere and clockwise in the S. Hemisphere.

What are the units? Looks like cm (centimeters) but that doesn't seem to make sense. Very cool map.

Yeah that tracks, Derby Jetty in the northwest has to be extremely tall to stay above high tide

I think it is centimeters, with this being only one component of the total tide so 1.3 m average is the max.

Bay of Fundy Tides: The Highest Tides in the World!​

Twice everyday the bay fills and empties of a billion tonnes of water during each tide cycle—that’s more than the flow of all the world’s freshwater rivers combined.

How High are the Fundy Tides?​

[/URL]

The Bay of Fundy has the highest tides in the world, and those enormous tides alone make that the Bay of Fundy is one of the world’s greatest natural wonders.

The height of the tide difference ranges from 3.5 meters (11ft) along the southwest shore of Nova Scotia and steadily increases as the flood waters travel up the 280 km (174 miles) of shoreline to the head of the Bay where, in the Minas Basin, the height of the tide can reach an incredible 16 meters (53ft).

For a very standard "Byzantium" survives map, that's a high-quality one. Kali chronia, Kyriakos.

I routinely wonder why the Byzantium lovers are limit their imaginings to Anatolia. Perfectly good claims much further south. What sort of strategic power player doesn't salivate over Suez?

Most such maps are slight variations of the country's borders under Basil II

^^^ What lovely maps! Choosing my favorite is difficult.

 

[Arakhor]

Not terribly sensible maps, I see.

Map shared by what seems to be an ISIS-K account

I like how they very specifically want only Portugal from the Iberian peninsula. Also how the Caliphate just skirts its way past Nepal to get at Bangladesh

What kind of caliphate doesn't control Spain? 2/10

They're afraid of the Basques? Seems like a good idea to give 'em a wide berth whether you're the Ummayads or Carolingians.

Tourism didn’t include s—x? Interesting! And that one about migration, that is true.
