Using a third party web service feature - how to clip to my local polygon boundary

Question

Hi all,

I'm using a national point data web service form a third party and I am only interested in the data for my local area in the web map, to which I have a small area polygon.

I wanted to ask is there a way to use arcade or something like this to just be able to perform something like a definition query on the layer, so the data that shows up only within my polygon boundary will be shown? I cant/don't want to edit/delete the additional data that is redundant for my purposes.

Many thanks!

Hi @LukeAllen2 ,

As far as I can tell that is not currently possible using Arcade.

Thanks Xander, in regards to the first suggestion, would arcade actually be able to hide/not show the points outside the study area? Thats what I am interested in, just being about to only show the points from the third party service that fall within my area of study (which would be my own polygon)

Hi @LukeAllen2 ,

I don't think it is possible to filter an external service using Arcade. Your options in this case are pretty limited with Arcade. You can show information in a pop-up that only applies to your study area (if the Arcade expression has access to the study area geometry), if that is what you are after.

As an alternative to the option provided by @Anonymous User , you could use a Notebook (ArcGIS API for Python, https://developers.arcgis.com/python/ ) and schedule the notebook to update a hosted service with a defined frequency.
