Postcode CV33 Issue #11
Description
The polygon is not closing it properly. I used turf library to get the difference of the area. This is the new polygon if someone needs it

Could you please fix it on Wikipedia so the source is correct.
Let me know and I'll run a new import.
https://github.com/missinglink/uk-postcode-polygons?tab=readme-ov-file#can-i-submit-a-pull-request
missinglink commentedon Oct 17, 2024
It's possible been fixed already? I didn't check
ro2wida commentedon Oct 17, 2024
Yes but I don't know where is the Wikipedia source, could you send me the link?
Also, I've noticed another issues with LE10, LE15 & NN14. And some NN polygons have extra coordinates.
I have the polygons already, so I can uploaded to the wiki too.
This repo I pulled yesterday so I don't think is fixed already.
missinglink commentedon Oct 17, 2024
It's literally just this one script:
https://github.com/missinglink/uk-postcode-polygons/blob/master/update.sh
The wikipedia page is:
https://en.wikipedia.org/w/index.php?title=List_of_postcode_districts_in_the_United_Kingdom&printable=yes
missinglink commentedon Oct 17, 2024
I just ran the script and there was only one change, which was unrelated:
#12
missinglink commentedon Oct 17, 2024
Agh, took me a second to find it, I think this is the page you'll need to edit:
https://en.wikipedia.org/w/index.php?title=Template:Attached_KML/CV_postcode_area
missinglink commentedon Oct 17, 2024
I've update the README with more info about editing Wikipedia:
https://github.com/missinglink/uk-postcode-polygons?tab=readme-ov-file#can-i-submit-a-pull-request
Let me know how you get on, it seems a bit tricky because wikipedia uses KML 🤷♂️
missinglink commentedon Nov 18, 2024
Hi @ro2wida, what should we do with this issue?
If wikipedia was updated I can update the data in this repo?
If it was too hard to do, I could help fix the wikipedia data?
hazem-alhazem commentedon Jun 2, 2025
I think this is relevant to my case, SW11 does not match with google's SW11 polygon, and as a result, adjacent polygons are not as well. How can we start fixing this?
missinglink commentedon Jun 2, 2025
Hi @hazem-alhazem, since this project is just a scraper for the wikipedia page which reformats to geojson, we need to edit this page directly to fix the polygon:
https://en.wikipedia.org/w/index.php?title=Template:Attached_KML/CV_postcode_area
almightyju commentedon Nov 26, 2025
@missinglink Can you run an update from wikipedia again? someone has update CV, LE and NN and they are all working for me now after updating locally
missinglink commentedon Nov 27, 2025
I updated it today.
