Since 2009 we have worked with the Ramblers to create a national web-based system for crowd-sourcing and managing high-quality walking routes. The process of developing and checking routes is enjoyed by the volunteer users, and has already built a library of several thousand walking routes. Quality control is ensured by a multi-stage workflow, within which all submitted data is double-checked and authorised before release.

These walks are then published through the main Ramblers web site, with user-friendly route cards and downloadable GPX files, allowing ratings and feedback from walkers.

A web service API also allows the data to be incorporated into other web sites on demand.
