Cannot Poll a Map service layer

Question

good day

I am trying to poll features from the National Weather Service map service at this URL

NWS_Forecasts_Guidance_Warnings/wpc_qpf (MapServer)

The feature layer is published as a Map Service. I've tried two things with no success:

- Add the layer to a AGOL

the layer gets recognized and published as Feature Layer and works in a Map Viewer

but when I a try to create a "Poll and ArcGIS Server Service", albeit the Service Name gets listed, once selected the Layer field doesn't list the specific layer endpoint

- Create a Data Store pointing directly to the Map Server Rest endpoint, but the behavior is the same. I can list the Service Name but not the layer id

I'd like to understand if a Map Server service (and not a Feature Server service) can be polled in this way and if not, what is an alternative workaround to poll features from the REST service.

thanks in advance

thanks Stefan!

I've tried again and can now poll the service, it takes a (long) while to update the data store catalog but eventually I can select the services.

The first time I tried ita gave me a weird error on a name field, but today at a second attempt I've been able to poll features from the service,

thank you for taking the time to test it,

kind regards

Hi Massimo Dragan‌,

I've just tested to poll features from the service (Layer: QPF 24 Hour Day 1) and it works fine.

All I did was adding the Server (https://idpgis.ncep.noaa.gov/arcgis) to the Datastore:

I am able to select the layer and the polling looks fine for me, without looking deeper into the incoming data.

Just try again

Best,

Stefan
