Affichage de différentes Basemaps (par ex. places)

DanielDormont

Bonjour,

J'essaie le nouveau service Places, et plus précisément d'afficher les informations des places sur ma basemap. https://jsapi.maps.arcgis.com/home/item.html?id=177e576ca3c94d5890dc3c790b29c1be J'ai trouvé cet item qui contient exactement les données que je recherche. J'étais enthousiaste de découvrir que vectorBasemapLayer de Leaflet permet de passer un ID d'item, alors j'ai essayé cela : https://codepen.io/dandormont-the-decoder/pen/eYQXOyr

Et il semble se charger, mais rien ne s'affiche et il y a des erreurs comme "duplicate layer id \"Religion place/Other Religion\", previously used at line undefined
at Object.Tr [as emitValidationErrors"

Comment puis-je charger une couche comme celle-ci en utilisant esri-leaflet ?

Merci, Dan

the map style https://jsapi.maps.arcgis.com/home/item.html?id=177e576ca3c94d5890dc3c790b29c1be is currently in beta release for evaluation only, and not considered ready to production use. Maybe the issues will get resolved once it is in production.

That's fair. I was more just trying to understand how map styles are loaded by the different clients and why this fails in this particular way

Well, I found a workaround but I wouldn't quite call it a solution. Some googling suggested that the "unimplemented type 3" error comes when mapbox/maplibre downloads a PBF that is incorrectly gzipped. So I looked into all the PBFs that were being fetched, and while there were no gzip issues, there was this curiousity:

https://basemaps-api.arcgis.com/arcgis/rest/services/World_Basemap_v2/VectorTileServer/resources/fonts/Arial%20Bold,Arial%20Unicode%20MS%20Bold/0-255.pbf?token=MY_API_KEY

which returns a JSON error "Requested font resource not available" which is obviously not a valid PBF. I'm not sure what that means but when I went back to the vector editor, I indeed found many references to "Arial Unicode MS Bold". By deleting all of these, and creating another copy of my style layer, I was finally able to get the map to load.

But I'm a little confused. Why doesn't that fontstack load? And why doesn't the Map Viewer / ArcGIS Javascript have the same problem?

DanielDormont

Hm. I partly answered my own question by creating a copy of that style and editing it in the Vector Tile Style Editor. I went into the JSON and manually removed the duplicates. https://dawx3gjaixmoyunx.maps.arcgis.com/home/item.html?id=69b1cd50b88945f6aaa2ba2b29f3640d

If I use that item ID instead, the map does start to display but I have a newer and more mysterious error: "Unimplemented type: 3""
