London Underground – The Journey of Life

This interactive web map explores life expectancy discrepancies between London Underground Stations. The output is a startling reminder of the importance of ‘place’ to people’s lives. It displays sharp contrasts between life expectancy on a small spatial scale. For example, Ladbroke Grove and Latimer Road on the Hammersmith and City line are separated by one stop (800 metres) but the average life expectancy is seven years higher in Ladbroke Grove.

My intention in designing this map was to create a memorable impression of the spatial inequalities along the routes travelled by Londoners each day. Within ArcGIS online, I uploaded a dataset which contained the average life expectancy from health clinics in London (total of 1436 health clinics) and created a spatial join to connect them to their closest underground station (total of 312 stations). The station then displays the average life expectancy (male and female combined).

Distributed GIS

What are Distributed Geographical Information Systems (GIS)? Distributed GIS are systems that do not have all the components in the same physical location. – Here a diagram complying with the old saying, “A picture is worth a thousand words”.
