Farthest from a GAA Pitch – Ireland
Ryan McGuinness has created a great website called GAA Pitch Finder with an accompanying dataset. His blog is fantastic and goes through geographic facts such as the highest elevation of pitches and each county’s GAA pitch with the largest nearest neighbour distance. The one fact I wanted to know was, what’s the farthest you can […]
Elevation Movie (2024)
I was watching the movie Elevation (2024) last night on Amazon Prime. It was a decent movie with a great premise; the aliens/monsters couldn’t attack any humans that were above 8,000ft (2438.4m). I thought that would make a really interesting map so I downloaded the 60 Arc-Second bedrock elevation of the ETOPO 2022 […]
Median Distance Between Built Up Areas – Ireland
I was rereading this article (warning: paywall) in The Economist from 2023 that states: In 1960 the median distance between African cities was 84.3km; in 1990 it was 55.7km. By 2015 this had fallen to 27.3km. This got me ruminating on what it is for Ireland? I haven’t done it historically, just for the latest […]
Black Bear Habitat and Place Names
This is a map I made to assuage my curiosity regarding the relationship between bear habitat and place names containing ‘bear’. I used the habitat of the black bear as it’s by far the most prevalent bear species in North America.
Most Remote Building in Ireland
Introduction I read a few excellent blog posts over the last number of years regarding how to calculate remoteness of buildings from each other. The two that stand out for me are Topi Tjukanov’s Searching for Isolation with GIS and Simon Wrigley’s Finding the most remote buildings in Britain which offer excellent methodologies on how to find […]
North or South of the River
This post is in response to a chat I had a few days ago with someone who was wondering whether there are more people north or south of the river in Perth. To answer this I’ve taken the ABS’ definition of Greater Perth (being the Greater Capital City Statistical Area [GCCSA]). The overall population of the […]

A quick map that shows the location of the Titanic wreck site with graticules included:
Driving from Perth to Sydney
I’ve driven from Perth to Sydney and back so I was curious as to what the route would look like overlaid on Europe so here it is. If you went the same distance west from Dublin you’d get to a small town in Labrador and Newfoundland called North River (population 579 in 2021).
Megacities of the World
I was recently reading the wiki page for megacities and I decided to try out the new curved callouts in QGIS by creating the below map.
Ireland’s Population by Altitude
I read Alasdair Rae’s very interesting post where he created a graph of Great Britain’s population by altitude. Using WorldPop data and the EU DEM I used QGIS, Seaborn and Inkscape to create the following graph for Ireland. I must do a bit of digging to see whether the 400 – 500 metre slight bump […]
