An international cycling map created from OSM data is available, provided by Andy Allan. The map rendering is still being improved, the data are updated every few days. It shows National Cycle Network cycle routes, other regional and local routes, and other cycling-specific features, such as:
  • dedicated cycle tracks and lanes
  • bicycle parking
  • contours and hill colouring
  • bike shops
  • proposed bike routes (or numbering protocols), contrasted with the Lonvia map, below, which does not show proposed routes, but actual routes only

Lonvia's Cycling Map by Sarah Hoffman is an overlay which shows marked cycle routes around the world. Updated daily, it renders actual routes without the state=proposed tag. Therefore no proposed routes (or numbering protocols) are displayed.

The National Byway is a signed, de facto leisure cycling route in the United Kingdom, mostly along quiet lanes and avoiding cities. It is currently 'under development': the route is scheduled[huh?] to open in summer 2010. At present (April 2011), there is no Internet mapping of the National Byway available, only an (as yet incomplete) set of paper maps. This is therefore a great opportunity for OpenStreetMap to provide such a map.

Tagging

The ways which make up the National Byway should be tagged using relations. Do not tag the ways directly.

There is one or more route relation for each region of the National Byway, and a separate relation for each signed loop. The size of each relation is currently restricted by what can reasonably be worked with - initially the National Byway was created a a single relation for the UK, but that soon became too large to manage.

Each route relation should be tagged as:

Tag Comment
type=route
route=bicycle
network=rcn
ref=NB Will display as a route label on the CycleMap.
name=National Byway (region) Include the name of the National Byway [region].
operator=National Byway

Relation role

The National Byway is keen on loops and circular rides, and in many instances these are signed in one direction only, generally anti-clockwise to reduce the number of right turns in the loop. It's difficult to follow signs backwards, so it is important for cyclists that the one-way sections of the National Byway are tagged correctly. Where the National Byway is signed in one direction only, the ways in the relation should be assigned a role of forward or backward as described in Relation:route#Members. The direction is rendered on the OpenCycleMap at zoom level 14 and greater.

Other optional tags are listed at Cycle routes#Relations.

Historical note

An earlier proposal was to tag the National Byway as network=national_byway, in conjunction with specific rendering in the OpenCycleMap, which was never implemented. The current tagging as a set of regional cycle routes network=rcn is now preferred: see [1] et seq. for the rationale.

Progress

One can see the 'outline map' at the National Byway website: [2].

Loops

To tag National Byway loops, create a new relation with the tags as above, and use the name of the loop, e.g. name=National Byway (Oakham Loop); consult this page on the National Byway site for a list of loops. Remember that loops are usually signed in one direction only.

Loops that have already been fully/partially mapped are as follows:
