Dr Duncan Smith, a Research Fellow here in CASA and author of our latest blog - Urban Geographics has produced an interesting visualisation of London's Urban form:

The data comes from the Valuation Office and the Greater London Authority. For more info and a write up of the background to the viz, take a look at http://www.geographics.blogs.casa.ucl.ac.uk
