Produced slightly more colourful example maps showing both ends of the distribution for absolute and relative difference in the distribtion of Twitter postings in Leeds
For details on the paper/presentation and my involvement at GISRUK please see my GISRUK 2012 Notes:
The following shows differences between afternoon and evening (red shows more in afternoon, blue more in the evening, grey is similar, white outside the study region, black are major roads)
Absolute difference flitered by reletaive difference
This work is based on data provided through EDINA UKBORDERS with the support of the ESRC and JISC and uses boundary material which is copyright of the Crown.
These images are also partly derived from data pulled from Twitter using the API that they provide.
