Decision Support for Small Earth Dams using Web GIS

Posted: November 8th, 2014 | Tags: | No Comments »

A dissertation submitted in partial fulfilment of the requirements of the Masters Degree in Geographic Information Systems of the University of Leeds.


The benefits of creating small earth dams for retaining water, both surface and subsurface, are multiple. The reserved water can be used for domestic and agri- cultural applications. Natural ecosystems will benefit as a result of the improved hydrological conditions, often helping to halt or reverse desertification by slowing down the large water cycle and preventing water runoff in the rainy season. Im- proved water retention improves conditions in drought-affected ASAL regions and lifts the burden of water carrying from women, allowing more time for family and education.

I was at Luminate Festival in New Zealand in 2011 and was inspired to make this digital painting.

Mapping No Religion Ireland

Posted: March 2nd, 2013 | Tags: | No Comments »

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.
