Mapping London is a new blog by James Cheshire and Oliver O’Brien, whose work we’ve seen before. Here’s how James announced it on his own blog: “Oliver O’Brien and I have decided to team up to launch the mappinglondon.co.uk blog for people who like to see maps of London without the techie blurb/ code you often see here. This is timely as there are some fantastic London mapping events in the pipeline (stay tuned) that I know will spread the good word about the geography and cartography of this great city.”
