There are a few tricks that allow you to shave off characters from OSM urls.
First, xyz.osm.org
generally forwards to xyz.openstreetmap.org
. This works for pretty much every first-party OSM resource.
Second, some OSM services have additional means to shorten URLs. For example:
- The map has shortlinks.
- This community forum allows you to omit topic titles and such from the URL. So this thread could be linked as community.osm.org/t/8748.
- Some Wiki pages with long titles have user-created redirects. And you can omit the
/wiki
part of the URL for all wiki pages. (I wish MediaWiki allowed making those shorter URLs the default.)
So your example of
https://tinyurl.com/psavpbv4
could be
https://wiki.osm.org/JOSM/Guide
Just 3 extra characters (32 instead of 29) and it gives the user an idea what the link is about without having to open all 3 of them first.
And of course, if you want to shave off characters from a printed URL, omitting the https://
would be an obvious next step.
A good start would be to make links like my example above more easy to discover. This could be a good addition to the wiki sidebar alongside the existing “Permalink” feature.
