[OSM-talk-be] Request to change the cycle highway network tag

[Pieter Vander Vennet]

Hello everyone,

Minh NGuyen had the following remark on the wiki
<https://wiki.openstreetmap.org/wiki/Talk:Tag:cycle_network%3Dcycle_highway>
about the current tagging scheme of the cycle highways.

Anyone any thought on it?


    Incompatible with cycle_network

This tag is incompatible with the predominant usage of cycle_network
<https://wiki.openstreetmap.org/wiki/Key:cycle_network>=*. This key was
originally intended to identify a specific network with uniform
signage – a renderer was supposed to be able to choose a shield based on
a combination of cycle_network
<https://wiki.openstreetmap.org/wiki/Key:cycle_network>=* and ref
<https://wiki.openstreetmap.org/wiki/Key:ref>=*. But it appears that
cycle highways are signposted and numbered differently in each country,
so there's no such cycle network as "cycle highway":

    Belgium

    Germany

    Netherlands

A renderer would have to perform a spatial query to reliably display the
correct shield for each of these routes, somewhat undermining the push
to have renderers use route relations instead of ref
<https://wiki.openstreetmap.org/wiki/Key:ref>=* tags on ways.

We already made this mistake once by repurposing the network
<https://wiki.openstreetmap.org/wiki/Key:network>=lcn/rcn/ncn tags for
routes outside the United Kingdom, leading to the otherwise redundant
key cycle_network
<https://wiki.openstreetmap.org/wiki/Key:cycle_network>=* as a
workaround. Let's avoid making this mistake again by deprecating
cycle_network
<https://wiki.openstreetmap.org/wiki/Key:cycle_network>=cycle_highway
<https://wiki.openstreetmap.org/wiki/Tag:cycle_network%3Dcycle_highway>
in favor of country-prefixed values like cycle_network
<https://wiki.openstreetmap.org/wiki/Key:cycle_network>=NL:cycle_highway
<https://wiki.openstreetmap.org/w/index.php?title=Tag:cycle_network%3DNL:cycle_highway&action=edit&redlink=1>,
or by choosing a different key altogether like cycle_highway
<https://wiki.openstreetmap.org/w/index.php?title=Key:cycle_highway&action=edit&redlink=1>=yes.
