= CycleStreets Photomap - cycle infrastructure examples from around the world".
"The CycleStreets Photomap is a user-generated resource containing over 56,000 images of bicycle-related infrastructure from around the world, for the purposes of cycling advocacy.
The Photomap is part of a platform being built by CycleStreets which includes a cycle journey planner (using OpenStreetMap), opt-in GPS tracking, collision data viewing, and more."
All locations are fully-categorised, and contain metadata such as type, good/bad, location, captions, keywords (tags), time & date: http://www.cyclestreets.net/photos/categories/
An API for third-party use is available: http://www.cyclestreets.net/api/v2/
It can also be used as the basis for tools for cycle infrastructure audit, e.g. http://www.urbancycleparking.org.uk/ which uses the same data interface (API).
