Re: > where to put the attribution when multiple sources have been

the data presented.

On (or on top of) the rendered map, in the same font weight as any
other logo or other copyright notice, and preferably with a clickable
hyperlink to https://www.openstreetmap.org (only required if this is
also offered for other features on the map).

The (c)Openstreetmap should be included if any other attribution is
included. If there isn't room for (c)OSM, then there should not be any
other logo or copyright on the map either. In in this case a generic
"i" or "(c)" link could be included to another page - so the only
situation where Openstreetamp attribution should not be shown on the
map is where there is not room for any attribution or logo.

The currently policy seems to allow rendered maps to show the logo of
the map renderer and copyrights of other data sources on the map if
they make up the majority of the data shown, without showing the
Openstreetmap copyright notice or link. I think it's clear that
several contributors disagree with this exception, myself included.

project, nor will the copyright policy directly affect me, except when
I print out maps, I suppose)
