[MVT] Cadastral Web Map Webmercator support?

[davidoesch]

IF opened https://mf-geoadmin3.int.bgdi.ch/mvt/index.html?topic=ech&lang=de&bgLayer=ch.swisstopo.swissimage&layers=ch.kantone.cadastralwebmap-farbe&lon=8.28411&lat=47.06703&zoom=17

-> does the WMS geoshop support the mighty webmercator? because we have the same issue here in 3D on prod https://s.geo.admin.ch/7e86023b3e

If geoshop wms needs an update please assign the ticket back to me so I can have a check with @beat-github and @ibele

geoshop does not support web mercator

<Layer>
<Title>GeoShop</Title>
<SRS>EPSG:4326</SRS>
<SRS>EPSG:2056</SRS>
<SRS>EPSG:21781</SRS>

But we only make requests in epsg:2056 (via cascading wms in wms-bgdi). It seems to be an issue in the tiled wms requests in mf-geoadmin / ol? @oterral any idea?

@ltclm Maybe try a non-null gutter in TOD

[ltclm]

there's no tod involved here. this is one of the tiled wms requests, done by mf-geoadmin: https://wms-bgdi-cdn-3.int.bgdi.ch/?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&FORMAT=image%2Fpng&TRANSPARENT=true&LAYERS=ch.kantone.cadastralwebmap-farbe&LANG=de&WIDTH=512&HEIGHT=512&CRS=EPSG%3A3857&STYLES=&BBOX=920301.8205448911%2C5952610.014745714%2C920607.5686580318%2C5952915.762858855

[procrastinatio]

OK, in the layersConfig. It looks like it's one of the few WMS layers without gutter param

Ping @procrastinatio

[ltclm]

i think any further work is out of scope for now, see @gjn comment: https://github.com/geoadmin/mf-geoadmin3/issues/4588#issuecomment-441601239

I would NOT start tangling with WMS configuration, proxywms configuration, etc. now.

[davidoesch]

So we set this on hold. No ETA for webmercator support for cadastral web map. We re analyse the situation after GL swisstopo decided if we use officially webmercator

[procrastinatio]

We also have to move AV-WMS into our infrastructure.

[davidoesch]

update: https://s.geo.admin.ch/8d67873ef2 ist still the case

[pakb]

on the new viewer, so it might be a bug in the code

Hey Patrick

Die ELZ Zürich möchte CadastralWebMap in Webmercator nutzen: es fehlt hier aber die Unterstützung im WMS des geoshops Kannst du das prüfen? Danke

[Ibelep]

WebMercator wird unterstützt im WMS des Geoshops.

Alternativ kann der WMS direkt bezogen werden: https://www.cadastre.ch/de/services/service/wms/cwm/data.html

[davidoesch]

Da der Endkunde einen WMTS in EPSG:3857 benötigt (offline caching von tiles) @Ibelep : wir müssen diese Anforderungen intern angehen. Bis dato haben wir keinen WMTS in EPSG:3857 zur Verfügung-- muss erstellt werden. Dazu muss dies via internes planning aufgenommen werden

[Lionardo]

Is there any update to this issue? The layer is still shifted on google maps WMTS in EPSG:3857
