UK outline map and Met Office Datapoint
I’ve been busy pottering on code as a mindless intermission during house repairs, can only do so much at a time. Argue with a piece of wood or with a computer screen? 🙂
This is a bitmap copy of a map of the UK with markers showing the location of Met Office weather sites with hourly data published via their Datapoint service. Data is under OGL (Open Government Licence) which allows usage. Unfinished work, references are not yet included.
The real file is part of a large PDF (vector format) containing plots for all those stations during a 24 hour period.

Some time ago I research and discovered a free usage source of country outlines and therefore usable for publication purposes. The database is from the whole world, in this case an extraction of a subset.

Once you know how it is trivally easy given moderate computer literacy to create a plot, costs time only.
I could produce plots for other regions if it is useful and I am inclined or I could tell you how to do it (I’m known for patience, we all start knowing nothing, enabling people is good). Broadly, get and install the database. Run the data extraction. Modify the result using a competent text editor, creating instruction data for a plot program. Is just move to this x,y. draw a line to this x,y and again. In this case I have used a permissively licence but little known program called GLE, which plots via Ghostcript, so those two have to be installed. A short GLE control script does the rest.

BSD licence, GUI you don’t need GPL
They recommend the vernerable
Ghostscript, Ghostview and GSview
Adding those markers is a whole different game. Actually the GLE script is produced by a program written in Lua..
If you don’t know Lua, err, best forget it. Is actually subtly very important. Technically superb. Is used commercially inside other works, getting ubiquitous akin to SQLITE.

Essentially MIT licence
Brazilian uni. open source closed development.
I’ll leave it at that.
