Anzeige verschiedener Basiskarten (z. B. places)

DanielDormont

Hallo,

Ich probiere gerade den neuen Places-Dienst aus und versuche speziell, Ortsinformationen auf meiner Basiskarte anzuzeigen. https://jsapi.maps.arcgis.com/home/item.html?id=177e576ca3c94d5890dc3c790b29c1be Ich habe diesen Eintrag gefunden, der genau die Daten enthält, die ich suche. Ich war begeistert zu entdecken, dass Leaflets vectorBasemapLayer das Übergeben einer Item-ID erlaubt, also habe ich das ausprobiert: https://codepen.io/dandormont-the-decoder/pen/eYQXOyr

Und es scheint zu laden, aber es wird nichts angezeigt und es gibt Fehler wie "duplicate layer id \"Religion place/Other Religion\", previously used at line undefined
at Object.Tr [as emitValidationErrors"

Wie kann ich eine solche Ebene mit esri-leaflet laden?

Danke, 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""
