Join features (spatial, intersect) analysis is missing huge patches of intersecting land areas?

lfern — Thu, 19 Jan 2023 17:35:46 GMT

On Arcgis online, I am trying to see overlap between two polygon layers using spatially join features (intersect). Why would a few large polygons from one layer that do intersect with my second layer be missing? This is an indication that others may be too...

Also-- I tried to extract the data table for the layer with more polygons (~16k features) so I could compare the number with the output of the join, but the csv output only has 802 rows?

What is going on here? Why are the AGOL analyses not working for me?

When you run analysis in AGOL, there's a box checked by default to run the analysis only for the current visible extent. Can you confirm if this box is checked or not? If it was, try running it again without the box checked.

Yes- I made sure that it was not for the current visible extent (and the polygon output layer were from the entire map-gaps were interior)...

I tried using the Overlay tool- and the outcome was 56 features (when 16k were in the original layer). See pic:

hi @lfern is this a feature layer you can share publicly? If so, we can try it out if you share the URL and parameters that you're using. If not, are you able to call support and they can help troubleshoot for you?

Thanks Sarah- I don't think I can share the layer. I'll try calling support though and will post an answer if we figure it out.
