Bringing pedestrian maps to Crystal Palace

By on 15th July 2014

I’m leading a Transition Town project to bring Legible London to Crystal Palace. You’ll have noticed these signs around central London, conspicuously absent across most of the rest of the capital: At the local Transition Town AGM, somebody suggested we

Densifying London (part two)

By on 18th January 2014

Following yesterday’s post on making London more dense, Tim Lund suggested I do a slightly more sophisticated analysis. Planners in London use a metric called the Public Transport Accessibility Level, or ‘PTAL’, which does pretty much what you’d expect. Rules

Making parts of London more dense

By on 17th January 2014

How do we build more homes in London? The Mayor’s latest exercise assessing needs suggests we need up to 690,000 over the next ten years, but a parallel exercise looking for land only came up with sites for 420,000 homes.

By on 8th November 2012

The OpenStreetMap GB project aims to measure and improve the quality of OSM data in Great Britain, cleaning it up to get rid of silly little data errors, and to make this cleaned up version available in formats that local

Analysing Southwark’s natural geography

By on 2nd November 2012

Following my map of London’s green and blue infrastructure, I have been working on some analysis of the land uses. I was inspired and encouraged to try this by Liliana’s interesting work called “imagining all of Southwark“. Lili and Ari

By on 26th October 2012

I’ve been playing around with open data from OpenStreetMap and Natural England to make a pretty map of “green and blue infrastructure” in London. Here’s the result: You can download a PDF version suitable for printing here:┬ánatural_london. I’m pretty happy
