Keep the new UK polygon data?

Thu, 17 Mar 2016 12:36:47 +0000

This week we have updated polygon data for the United Kingdom. This included updating data for Scotland which had old and very broken data before, and for Wales.

It also ended up with some changes for England. We have used the data from OpenStreetMap as we normally do. For all other countries we use the data defined as administrative borders. Their data is described here, http://wiki.openstreetmap.org/wiki/Tag:boundary%3Dadministrative.

The OSM data can be viewed online here, https://osm.wno-edv-service.de/boundaries/

We know many argue for using ceremonial borders for UK. Our tools doesn't allow that today and it would be quite a lot of work. Our old data didn't use them either, so there is no difference for this case. All other countries use the administrative borders, so it's a way more consistent with the rest of the world.

Considering we are using Metropolitan and non-metropolitan, the data we have now should be as correct as OSM has it. The future changes should then be minor, and only change if OSM changes their data (not live, it's still a manual task).

The question is, should we keep this data, or use the old data? Remember, using the old data will ruin the data of Scotland again.

We also just fixed a bug with the maps in Profile stats. If they rendered weirdly for you, hold down shift or ctrl while refreshing the page and it should fix itself.

Feel free to leave a comment about your thoughts.
