How to configure alternate ArcGIS Online background maps

Hi @ferdinandbogman​ 

Unfortunately, I'm not certain you will be able to use the custom background maps within FME 2020.

However, it appears that the map services are offered as a web map tile service (WMTS). Our development team is currently actively working on adding support for WMTS and plans on exposing it as a Background Maps format. Once support has been added, then it may be possible to use the background maps at the link you have provided.

I will update this post once support for the WMTS has been added in the Data Inspector.

Hello Debbi,

Thanks for your reply. To make things clear, I am not looking for a possibility to use WMTS. The services I want to use are perhaps also offered in that format. So it might be an alternative, once it is available.

But their primary format is the ArcGIS (cached) map service, just like the ArcGIS.com services.

So my question narrows down to finding a way to use an alternate URL which behaves just like the standard ArcGIS.com URL. That includes not having to authenticate.

Hi @ferdinandbogman​ , 

The ArcGIS Online background maps that are used in FME Data Inspector are primarily Web Map

Steps to create ArcGIS Online Background maps 

• From the services that you mentioned click on Donkergrijze_Canvas_Referentie https://services.arcgisonline.nl/arcgis/rest/services/Basiskaarten/Donkergrijze_Canvas_Referentie/MapServer
• On this page, notice that there is URL similar to below http://www.arcgis.com/home/item.html?id=25b5f901bd8d418481a18f87ce9b1358
• Copy the id part(25b5f901bd8d418481a18f87ce9b1358)
• Now go to FME Data Inspector --> Manage Background Maps --> Select ArcGIS Online Maps 
• In the Map dialog, add the following 

foo (25b5f901bd8d418481a18f87ce9b1358)

Screenshot below  NOTE:

I notice that you feature service is using EPSG:28992 which may not work

Our ArcGIS Online background map shares code with the other Python-based background map formats. They all assume a system that has min/max zoom levels and XYZ integers that uniquely identify a single map tile and they’re all Spherical Mercator (AKA Web Mercator).

foo (25b5f901bd8d418481a18f87ce9b1358)

Thank you rahulsharma,

The procedure you describe worked, after I discovered that I forgot to place the brackets around the item id ;-).

But, as you warned me, the coordinate system is messing things up. The services are only available in EPSG 28992 since they are meant for underlaying dutch data. So even in Spherical Mercator I can't properly use it to view my data.

Neither are they served as WMTS, so I seem to be on a dead end street here.

Thanks for spending time on this, I will consider suggesting this as an idea: the ability to use other coordinate systems with ArcGIS Online layers. 

Regards,

Ferdinand
