Hi @flob38 !
I cannot access https://forum.camptocamp.org/t/bascule-des-geoservices/324653 (I suppose the page is private?)

[flob38]

Should be ok now, I added you to the dev group on the forum :)

Seems to have been mostly done here: 143e68d

Just wondering about :

c2c_ui/src/components/yeti/map-layers/WinterRouteLayer.vue

Line 38 in 3e3f07f

url: 'https://wxs.ign.fr/an7nvfzojv5wa96dsga5nk8w/geoportail/v/wms',

I guess it should be url: 'https://data.geopf.fr/private/wms-v/ows?apikey=blabla' (with blabla the keyname according to https://geoservices.ign.fr/documentation/services/utilisation-sig/tutoriel-qgis/gpf-wms-wmts-donneesnonlibres)
cf doc here https://geoservices.ign.fr/bascule-vers-la-geoplateforme "Correspondances des URL par géoservice".

@florentcadot I agree we should try to migrate TRACERANDOHIVERNALE, but I think it's not available yet.
when when I compare the "capabilities" of the old (1), new private (2) and new public (3) urls:

(1) https://wxs.ign.fr/an7nvfzojv5wa96dsga5nk8w/geoportail/v/wms?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetCapabilities
(2) https://data.geopf.fr/private/wms-v/ows?apikey=ign_scan_ws&service=wms&version=1.3.0&request=GetCapabilities
(3) https://data.geopf.fr/wms-v/ows?service=wms&version=1.3.0&request=GetCapabilities

only the first one mentions this layer:

14201:        <Name>TRACERANDOHIVERNALE</Name>
14202:        <Title>TRACERANDOHIVERNALE</Title>
14203-        <Abstract>Layer-Group type layer: TRACERANDOHIVERNALE</Abstract>

If I take a layer that is declared in (2), it works. example:

curl 'https://data.geopf.fr/private/wms-v/ows?apikey=ign_scan_ws&REQUEST=GetMap&SERVICE=WMS&VERSION=1.3.0&FORMAT=image%2Fpng&STYLES=&TRANSPARENT=true&LAYERS=ADMINEXPRESS_2023-12-19&WIDTH=256&HEIGHT=256&CRS=EPSG%3A3857&BBOX=682429.7885300554%2C5576845.58368646%2C684875.7734351811%2C5579291.568591585' \ -H 'user-agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36' \ --output ign-ADMINEXPRESS_2023-12-19-sample-tile.png

If I just replace ADMINEXPRESS_2023-12-19 with TRACERANDOHIVERNALE I get instead:
<h1>Error 403</h1> <p>Unauthorized access to the offering TRACERANDOHIVERNALE</p>

which is actually a generic error for any random name!

→ so I think it's just not migrated yet. (hard to be sure as geoportail itself still uses the old URLs...)

I asked IGN and they confirmed "not yet"

La publication de cette couche est bien prévue, vous pouvez consulter depuis la page Bascule, la Liste des ressources de services Géoplateforme

La couche TRACERANDOHIVERNALE est indiquée comme non diffusée pour le moment. Elle le sera avant l'arrêt de l'infrastructure du Géoportail.

Okay ! Thank you very much for all those details @eddy-geek, it's very clear 😄
So it makes sense to keep this issue opened until TRACERANDOHIVERNALE is published!
