How do I extract attachments from an ArcGIS online feature service?

Hi @liskett162​ ,

To read attachments from an ArcGIS Online Feature Service, there is a reader feature type parameter "Include Attachments" which you set to "yes" (by default this setting is set to No):

And then you will want to expose the arcgisonline_attachment{} format attributes:

The arcgisonline_attachment{}.data attribute holds the raster data which you could then use the RasterReplacer to recreate the image.

Hope this helps!

Hi @andreaatsafe​ ,

I don't seem to find the include attachments parameter for the ArcGIS Online Feature Service using a feature reader.

Any ideas?

PD.- I am using FME 2022.2.4 Build 22792

I have not checked this in 2022, but in 2021 this option only exists in the classic reader, not in the FeatureReader.

Correct @nielsgerrits​. I just put in a case for the Include Attachment parameter to be visible in the FeatureReader. On the flip side, for Portal, the classic reader does not have Resolve Domains parameter that is visible in the FeatureReader.

UX & parameters for the FeatureReader is complex but there must be some certain amount of parity on the important ones.
