Může PowerBI zobrazit na mapě data z ArcGIS REST endpointu?

Question

V tomto případě se snažím _ne_ používat ArcGIS pro PowerBI, protože mám uživatele, kteří jsou pouze Viewers, a ArcGIS Maps pro PowerBI podivně vyžaduje, aby uživatelé měli roli Creator, i když chtějí jen zobrazovat služby. <\/P> Takže mě zajímá, jak \/ jestli je možné poskytnout uživateli REST endpoint pro bodovou, polygonovou nebo liniovou službu (např. https:\/\/mygis.domain.com\/arcgis\/rest\/services\/demopolygon\/MapServer\/0\/query<\/A>), a připojit to k mapě v PowerBI (nástroj bing map). <\/P>Jsem zde v PowerBI úplný nováček, takže pokud existuje nějaká dokumentace nebo krok za krokem návod, bylo by to skvělé. <\/P> Pokud to není možné, proč pak uživatel potřebuje roli Creator, aby mohl pouze view<\/EM> vrstvy?!?!<\/P>

Hi @Jay_Gregory  - I am working on the same thing. We don't even care about the map component, just using the underlying data. This article is really good at stepping you through the process - https://resource.esriuk.com/blog/how-to-use-arcgis-with-power-bi/

Though I have come across several issues so far including date/time formatting, how to pass credentials for secured data, and having to publish services that allow for over 2000 records to be queried at once. If you have found a better way please let me know!

Yes it is basically pulling in the JSON result of your REST query.

In the PBI query Editor, put something like the following for the source and followed with some data transformation steps:

=Json.Document(Web.Contents("ArcGIS Rest Query here"))

The ESRIJSON part will be a little tricky to deal with, but it's doable.

To avoid the license issue for the viewers, your content needs to be shared with everyone in AGOL or Enterprise.

Even if users do use Maps for Power BI (with Creator license), they need to a) display some data (drag lat / long fields from power bi to get any map to show) b) still no way to pull in an arbitrary REST endpoint.  It would need to be added as an item in Portal or Online for a PowerBI user to be able to see in it Maps for PowerBI.
