Welcome to EarthHack

Hi! I’m David Anthony McNamara, a software developer with special interest in environmental and social issues.

I believe creative use of geospatial information technology can help solve some of the planet’s most pressing issues. I love finding imaginative ways to visualise and explore data.

Have a look around and please get in contact if you think we could work together.

Mapping No Religion Ireland

This map shows the percentage of people per electorial division that classified themselves “No Religion” in the 2011 Census in the Republic of Ireland.

Perhaps predictably, the cities can be seen to be generally non-religious. However, it’s interesting to note that outside the cities, some areas in particular have clusters of non-religious divisions. These areas seem to correspond with those traditionally associated with people seeking an “alternative lifestyle”, e.g. West Cork and County Clare.

This map was compiled from census 2011 data. I used GDAL to reproject, simplify and convert the Census ED Boundary shapefiles to GeoJSON. I uploaded the GeoJSON and the SAPS data to CartoDB and merged the tables. After that, CartoDB made it a pleasure to style the map and info windows.
