The Environment Protection Agency also provide GIS data openly including one called Geometric River Network, which seems more along the lines of what the map maker has used.Which will let you do something like this

Just to add to this, the EPA one uses data originally taken from OSi data as well. In the download there is a field called ORDER_ or similar. The higher the number, the more prominent the river. So the Shannon main channel is Order 7, and drainage ditches and streams are Order 1. So just style using this field to display the main channels more prominently.

Also, another tip, if you style using the HA (Hydrometric Area) field, you will see the Nore, Barrow, Suir for example, display individually colored as well, rather than being grouped together.

Norway's the only one not an island.

Are those islands at the very North considered Norwegian?

Svalbard

They're not considered Norwegian, they are part of Norway.

They have a lot of research facilities on them.

https://en.wikipedia.org/wiki/Svalbard Svalbard archipelago is Norwegian territory, but other countries have certain rights.

https://en.wikipedia.org/wiki/Jan_Mayen Jan Mayen has a different status.

on that river basin map, geographically, how do we explain those tiny short rivers along the coast on that map, are they accurate? they arent tributaries of another river as far as the map indicates. or is it that the image shows all rivers of a particular size and so these have appeared on their own but actually have smaller connections that down show up because of their size? sorry, probably thinking too deep about this but it has me wondering!

You can set a minimum catchment area. Set it low enough, and you will pull out the localised rivers near the coast from the digital terrain map, in addition to the main rivers which connect up pretty much everything else across the inlands.

I would guess he has used the SRTM dataset (available on USGS earth explorer). Might have a go a recreating it at the weekend.

I suppose we can now start measuring Amazon destruction in Death Stars' rather than Wales'.

What are the two things next to the Death Star, with the yellow arrow pointing at them.

They're other ships. You see it in the video.

That map showing the sunken land parts of NW Europe is very cool. Makes you wonder was there settlements along the shorelines there, settlements inland a bit that were ultimately drowned into the sea. That's where most settlements set up, along the shorelines. Is this where the ancient folk stories of floods and cities lost underwater come from?

You should check out the former sprawling town of Dunwich which has withered away over the last 700 years:

A prehistoric "Atlantis" in the North Sea may have been abandoned after being hit by a 5m tsunami 8,200 years ago.
The Storegga slide involved the collapse of some 3,000 cubic km of sediment.

As we were talking about the catchments map, I came across this of watersheds in the USA. Not sure if it’s been posted already

Tell me how

Anyone familiar with the New England region of the US will know that there is no shortage of names which are more familiar to many Irish people because of their place in either the UK or indeed Ireland.

Two of these names in particular made me laugh when I first heard about them.
One is named London Derry, and the other Derry in the state of New Hampshire. (See bottom right hand corner of the map) And they are separated by the Interstate I93 passing between them

Originally Derry was part of Londonderry until it was incorporated as it's own town in 1827. I wonder what the conversation was like when selecting the name of the new town and was there much or any resistance from the Londonderry residents towards the new name.

I have spoken to people living in the towns now and they had no awareness of the significance of the town names back in Ireland (where many ascendants of the town originated from). I kinda hoped they'd have a Springfield - Shelbyville or Pawnee - Eagleton type of relationship between them.

Evolving social network of Officer Raymond Piwnicki.

From a 2018 article mapping complaints against cops

About 1,300 out of 30,000 of Chicago’s cops fall into clusters of linked police officers

Because complaints can list multiple officers at once, it’s possible to determine that more than one cop was present at the scene at the same time.
...
The illustration above visualizes such a social network. Dots represent officers, linked by lines of complaints. Most officers register few complaints and sit on the outside of the network. But a small portion of officers at the center of network behave differently than those on the outside.

Seeing the two towns side by side still brings a smile to my Face.
Thanks for the research you did, I never looked up the towns history’s.

Selenium sulphide - Selsun - shampoo is what keeps my dermatitis at bay. The feckers have stopped making it! I'm eking out the last of two bottles the chemist ordered in from Spain at enormous expense.
