Cartographicum Thandeum

I'm debating whether it's worth adapting the old Boothroyd base map for the new UK parliamentary boundaries or not. On the one hand there are much better base maps now, but I do like the idea of perpetuating comparable election maps.
 
A random ASB idea I had, which seems obvious now but I don't recall being done before - Pournelle's CoDominion but in the classical era:

Someone with better graphics skills than me can probably do something with an eagle and dragon (or some more specifically Han symbol).
 
It's been FOURTEEN YEARS since we got some new national constituency boundaries in the UK (longer if you're Scottish) and the last time things changed, I was still using basemaps other people had made. This time, I've decided to make my own - albeit it is derived from the one on Wiki, but the one on Wiki is also WRONG and I've had to make numerous painstaking corrections. This has been an exercise in frustration as there are multiple versions of the boundaries floating around (including different versions from the Boundary Commission, not always making it clear what are final and what are original boundaries) and I eventually resorted to treating the Guardian's interactive map as the gospel truth, seeing as it's the most recently updated. Incidentally, it's a very good map, it's almost as good as the one the BBC website used in Flash for the 2005 general election, against which literally every subsequent BBC attempt is objectively laughably inferior.

In addition to fixing the actual factual errors, my version improves on the Wiki one by using a philosophy of easy recolouring - single-pixel boundaries (which also look more aesthetically pleasing), simplified coastline and the elimination of all but the largest islands. Although I definitely racheted my threshold up and down inconsistently as I made my way around the coast. I also got rid of the more egregious city insets, many of which didn't even magnify the area in question significantly. I was going to cull even more of them (some are obviously necessary like London) but I reluctantly decided I might as well keep the rest. That Channel Coast one (which had a much stupider name in the original) is probably borderline unneeded, as is Derby & Nottingham, but sod it, that one can stay as it has Erewash as the centre and all psephological maps need to highlight @Alex Richards' contributions in some way. And I'm not risking offending anyone in Belfast.

Yes I've just reassigned the UKIP colour to Reform UK even though they don't use that, shut up, I am not trying to manage with two slightly different blue scales, I am not letting this turn into our version Japan's infinite shades of green. It's not as if they'll win any seats anyway.

So anyway, here it is, the final* blank map until I find an error. I intend to populate this with the notional results shortly.

Great work. And the original one is an .svg which means the detatched areas are probably all single shapefiles for easy colouring. Not that that helps anyone using a raster program rather than a vector one.

EDIT: Though thinking about it, does it fit if you swap the locations of Belfast and the Notts-Derby insets on that map, because there's just someting bugging me about how Belfast is sitting off the east coast of the country rather than being near Norn.

Yeah, nothing will ever convince me to use vectors - that goes back to my days in the mid-90s trying to find editable map gifs that weren't so low resolution they didn't show Newfoundland as an island.

That makes sense about swapping those insets, I did find that an odd choice.
 
Discussion point: rather than trying to continue my 1922-2020 US House election series by further extending those series, I'd like to instead add post-2020 updates to a new series that starts only a few decades back, but incorporates presidential results by House district alongside the actual House results for each state.

I was debating how far back to go for this - 2000? 1980? I've just found a good source which has the presidential results going back to 1952, but that's farther back than I was thinking. It'd be nice to try to capture the presidential transition running ahead of the House one and people split-ticketing, which I think realistically needs to go back to at least 1990 if not the 1960s. What's your opinion, map thread watchers?
 
To my mind, 1972 has always felt like a good point for showing that transition. The Southern Strategy becomes increasingly obvious at the Presidential level from there forward, but it doesn't really trickle down to the House level until the Gingrich wave of 1994, and it doesn't really complete itself until the mid-2000's (minus a very slight reversion in 2006 and 2008).

Thanks, that's a good point.

I know me so I'm probably going to talk myself into doing it 1952 onwards anyway...

Aren’t a majority of county-level officials in the Deep South still Democrats?
 
Here's a prototype of those House vs presidential by CD maps I mentioned, covering Alabama 1952-1990 (as it's alphabetically first and also has some of the starkest difference between those two in this period of upheaval).

I'm also going to add a colour scheme with a different colour for each district number (and keep that consistent across all states) to help demystify the redistricting maps so they're not just grey with green numbers.

In addition, the final version will not have the lime green lines which are only there for scaffolding purposes.

Any other thoughts on this model?

I do like using the presidential results by CD to compare. The district maps are a bit awkwardly placed, but it's not like you could place them less awkwardly.
Not without creating another line and wasting a lot of space, yeah. The main reason I did it this way (other than avoiding the previous system I used where the map for the year where redistricting happens just has numbers on so there's no clean version) was precisely because otherwise you'd end up wasting space for non-presidential years. But year it does mean sometimes the district maps aren't in the most logical place in terms of time placement.
 
I'm thinking I might also add a small circle (not a state outline) in the corner of the presidential by CD maps just to show the statewide vote as a reminder. I was thinking I couldn't do that without having one for the House vote as well and those are tedious to sum up, but on reflection there's no reason why I can't just show it for the presidential vote. Certainly some of the results above (e.g. 1980) don't make it obvious to the eye whether, in that case, Carter or Reagan actually won Alabama's electoral votes (it was Reagan, but by a margin of just 1.3%).
