The University of Openness (previous entry) has a new project to make copyright-free street maps of London; the page explains the details and MO, but it looks like it’ll involve an awful lot of GPS tracing and GIS data processing from diverse sources and by divers hands. It must be said that, like many open-source projects, they’re essentially reinventing the wheel in order to make it free/freely available — and doing it harder. Via Here Be Dragons.
