(Canonical version of this post is on “Sports in Ireland & Britain” on Technomancy)
I created some software to generate heatmaps from OpenStreetMap, here’s what OSM’s sport tag looks like for t̶h̶e̶ ̶C̶e̶l̶t̶i̶c̶ ̶I̶s̶l̶e̶s̶ Ireland & Britain
When you have checked out the code from Sourcehut (or Github), then run make build-deps to install requirements.
Then download the data:
$ make data-ireland-and-britain
Look at the spread. Initially I ran it withouth steps=..., and tried different values until I got something that looked nice.
$ make heatmap_key key=sport steps=0%,1.5%,4%,10%,22%,35%
Unsurprisingly, this shows urban populated areas. On average Britain, even rural areas, have a higher score than rural Ireland. It’s hard to know if that’s because of less mapping in Ireland, or less sporting facilities, which might show a difference in cultures.
Let’s see what’s popular:
$ make list_values key=sport
$ head list_values_sport_bboxALL.txt
Not terribly surprising.
Make an overview of the top 10:
$ make montage_top_10_sport_bboxALL_stamped.png key=sport
Unsurprinsgly sport=gaelic_games is popular in Ireland, and sport=cricket is popular in Britain. The default steps of 0%,25%,50%,75% can be useful, but as you can see with sport=golf,=tennis,=soccer, it’s not always useful.
Cricket in Britain
$ make percent key=sport value=cricket steps=0,0.1,2,6,8,9
“Cricket?! In Yorkshire!”o
Gaelic Games in Ireland with the same colours shows much more gaelic games facilities mapped in Ireland compared to cricket facilities. Hon the parish!
$ make percent key=sport value=gaelic_games steps=0,0.1,2,6,8,9
$ make percent key=sport value=rugby_union steps=0,0.5,2,3.5,5,10
Munster Rugby showing well:
Rugby League, with the same scales. Clearly it’s not as popular in OSM as rugby union:
$ make percent key=sport value=rugby_league steps=0,0.5,2,3.5,5,10
In OSM, there seems to be a high number of golf clubs mapped around Inverness, Scotland:
$ make percent key=sport value=golf steps=0,2,5,10,20,30
The English West Midlands seems to be dominating the horsey set:
$ make percent key=sport value=equestrian steps=0,3,15,40,50
The software to generate this can be found on Sourcehut or Github. If you create any interesting heatmaps email me!, or leave a comment below.

The golf hotspot around Inverness seems to be because of three golf courses with every tee, fairway, green and bunker tagged with sport=golf - that’s 1/4 of all those tags in Scotland :) https://overpass-turbo.eu/s/Try

Very interesting, you can see the bias of coastal places for golf and the specificity of Ireland’s largest sporting activity.
