Code-Point Open – Northern Ireland Addendum
In April 2010 Ordnance Survey released The Code-Point Open dataset under a licence compatible with the Creative Commons Attribution Licence. The dataset locates, by OSGB grid reference every postcode unit in England, Scotland and Wales. Northern Ireland is missing. You can read more about the limitations of the Code-Point Open dataset in my previous post
All is not lost though. The Northern Ireland Statistics and Research Agency (NISRA) provide the necessary data. As far as I can tell this is freely reusable under the terms of the Click-Use PSI Licence.
NISRA provide the data in MapInfo or ESRI Shapefile format. The coordinates are in Irish Grid Reference format. For ease of use I have re-exported the data as a single CSV file.
| Column | Length | Name |
|---|---|---|
| 1 | 7-8 | Postcode |
| 2 | 1 | Active |
| 3 | 6 | OSI Easting (X) |
| 4 | 6 | OSI Northing (Y) |

Hi, I’ve put together a walkthrough describing how I built a UK postcode -> lat/long mapping from the OS and NISRA data, which might be of interest:

I’m wondering whether you used the same tools to generate your data from the NISRA dataset?

Hi,
Sorry to post this here coz it’s irrelevant. But do you run the spread-shirt ‘crapola’ store? It re-directed me here when I tried to send email.
If so can you email me? I have a question.
Thanks

Hi Jamie, really like your work. If you get a moment, we would love to talk to you about a project we are working on for VisitBritain, which involves adapting streetview.
Just email me if you get a moment. Many thanks

@Kieran I didn’t go as far as you. I didn’t convert the OSI coordinates to WGS84 lat/lng pairs. Partly cause I’m lazy, partly… well no mostly cause It was late and I couldn’t be bothered
@Kate Yes I used to, but not anymore.
@Teddy Interesting…

Hi,
I’d like to link to this snippet of information, but I can’t find the original source of the NI postcode data you’ve used (the licence page is much more general). Could you include a reference to the original/official source of the data?
Thanks!

Sorry Dominic, I hadn’t noticed until now that I hadn’t linked to the source… but you’ve just done it for me
