Python-Quick Graph
I’ve never really had cause to use Matplotlib before so over the weekend I took a quick look at it and how useful it actually is for creating quick graphs. I took the electricity connections dataset (used as a measure of new homes built, however rough) and created a simple line graph. Below is the…

Isochrones-Ireland and Australia
I was reading Topi Tjukanov’s fantastic post yesterday on how far you can drive in one hour from European capitals. This got me thinking, wouldn’t it be interesting to compare driving distance for somewhere in Ireland and somewhere in Australia. For Ireland I chose the geographic centre and for Australia I chose my fiancée’s home city of…

Ireland, A Country in Motion: Methodology
I promised late last year that I’d do a blog post explaining how I created the ‘Ireland in Motion’ commuting map. Well, this is that post! The first thing to say is, that until the ’16 census results came out it wasn’t possible (as a member of the public) to create this type of map…

Ireland-A Country in Motion: 1.96 Million Commutes
I was inspired by Alasdair Rae’s excellent work here, here and here to attempt something similar for Ireland. Below is the fruit of my labour over the last number of weeks. It shows 1.96 million individual commutes from every electoral division in Ireland. Commutes within a single electoral division are excluded. The data comes from the Irish Central…

Global Human Settlement Layer-Cork
During the course of the last week I was reading the MacKinnon report (otherwise known by its succinct title of ‘Report of the Expert Advisory Group on Local Government Arrangements in Cork’). This is the report that address whether the administrative boundaries of Cork City Council should be changed. The report recommends a large expansion…

Global Human Settlement Layer-Dublin
I’ve been taking a look recently at the Global Human Settlement Layer from the the European Commission. I’ve been working on a piece to do with the physical impact of the Celtic Tiger on Ireland, but in the meantime, I’ve put together a few fun GIFs using their built up data. This uses a combination…

QGIS-Generating an Isochrone
Normally with somebody asks me to undertake a quick bit of analysis it usually involves, ‘Can I see all of x features that are with 2000m of this location?’. The other day I got asked: ‘Can you give me a spreadsheet showing all locations of x within a 12 minute drive of this location?’. I…

Irish Census 2016
The CSO released the results and geometry for the small areas (the largest scale available) on the 20th of July 2017 (available here). I downloaded all the data and used FME 2017 (with my shiny new home use licence) to join the geometry and CSVs and write it to PostGIS which was then brought into…

Unpopulated Australia
I was looking at a map highlighted on Reddit the other day from the website mapsbynik. It showed the unpopulated areas of the United States. I was going to do a similar exercise for Ireland but when I examined the census data it quickly emerged that no ‘Small Area’ (the unit with the finest spatial…

Farthest McDonald’s-Ireland
In my last post I downloaded all the McDonald’s in Ireland using overpass-turbo. The problem I had when I exported these was that because GeoJSON is such a flexible format, I was getting both nodes and ways. These would have had to be imported into ArcMap separately and the centroids of the ways found and…
