I think the wisest approach is client-side rendering of OSM data, which would allow for map display for any resolution/density, and even allow customization according to user's interest. An example can be found on opensciencemap.org <http://opensciencemap.org/map/#&scale=11&rot=1&tilt=0&lat=45.758&lon=4.894> .
Any idea if the OSM website is intended to switch to client-side rendering like Google Maps did a few years back ? 2015-01-28 22:40 GMT+01:00 Michael Meier <[email protected]>: > On 01/28/2015 01:32 AM, Paul Norman wrote: > > It would be up to the system administrators and OWG to decide if they > > wanted to deploy retina tiles.
