Cycle routing reflecting real cyclists’ desire-lines needs good quality data. Earlier this year the UK's Department for Transport made available cycling data for England collected from surveying they had undertaken over a few years. This has been converted to an OpenStreetMap-compatible format to enable OSM community volunteers to merge in the data. The geometry has been 'snapped' to OSM geometries with intelligent matching of paths, and the metadata has been converted to using the OSM tagging system. We funded the creation of a merging tool which enables mappers to merge the data. Martin will talk about some of the project’s challenges and opportunities involved and will ask what scope there is for future 'manual merging' projects.
