A public service called “cartes.gouv.fr” was created in France. As I understand it, this will lead to the disappearance of “geoportail.gouv.fr”.
Every map producer is free to submit their DB to it.It would be good if an OSM working group took charge of this.The contact email for this public service is “ cartes.gouv@ign.fr”.
Philippe, je te suggère de plutôt contact la communauté OSM France sur https://forum.openstreetmap.fr
oups, oui, corrigé
geoportail.gouv.fr has already an OSM layer.
That’s right. My alert is to ensure continuity.
The question can be phrased as follows: what is the current OSM database support mechanism for geoportail.gouv.fr, and will it be continued in cartes.gouv.fr ?
If this mechanism is managed by the OSM community, then migration needs to be considered.
If this mechanism is managed by the IGN (French Geographic Institute), then proactive action is required.
After some research, here are two links that describe the process of submitting cartographic data to cartes.gouv.fr.
which one of working groups?
why OSM Working Group should work on supporting french government website? Are they having no plans to include this dataset on their own? Can it be send only by an official representative?
Is there documentation in English (it is French government website so probably not)?
likely contacting fairly active local French community will be better - they will do better at navigating French government website and judging how this should be acted on and whether anything needs to be done

I have no idea.

This French government website is intended to host any geographical maps, not just those from the French geographical institute (IGN).
I am a hiker and, to prepare my hikes, I stack different layers. OSM is always one of them. I use geoportail.gouv.fr for this, which is due to disappear (I think).
Are they having no plans to include this dataset on their own?
I contacted “cartes.gouv@ign.fr,” who told me that they (IGN) would not initiate anything, that it was up to OSM to act.
Can it be send only by an official representative?
Anyone can submit a map for which they hold the rights.

no !

I’m not sure about that.
IGN’s géoportail is currently offering the OpenStreetMap France base layer as an option, mostly for international maps as IGN is covering only France.
They simply setup a proxy to our tile server, not hosting anything on their side and there is not copy of OSM database or tiles.
OSM-FR is not managing it on the géoportail itself, this is done by IGN.
I can check what is planned at IGN to keep offering this base layer on cartes.gouv.fr (I’m working part time at IGN, on Panoramax).
Currently the only OSM based layer is Plan avec OpenStreeMap with data outside France only, with a classical IGN rendering. You can move to Strasbourg (France) and move close to Kehl (Germany) put this layer over Plan IGN, making the layers visible/invisible: Cartes.gouv, clipping doesn’t seem to be a well known concept at IGN ;-).
I’ve seen that. It is a completely different approach compared to having an existing OSM raster basemap. Both are useful.
