I'd recommend trying out Experience Builder.

You could join https://pro.arcgis.com/en/pro-app/latest/tool-reference/data-management/add-join.htm the buffers to the tabulate intersection table by matching field. If you need to have your data clipped to each buffer for some reason, then Intersect https://pro.arcgis.com/en/pro-app/latest/tool-reference/analysis/intersect.htm might do this for you without merging the geometries.

To achieve this by your initial method, I would first convert your polygons to points (centroid points) but use the https://pro.arcgis.com/en/pro-app/latest/tool-reference/data-management/feature-to-point.htm tool to ensure the 'inside' option creates them within the polygon. You'd then have output points with the same attribution as your census polygons - then use the points as input into the spatial join, replacing the previous polygon inputs. A completely different approach would be to use Tabulate Intersection https://pro.arcgis.com/en/pro-app/latest/tool-reference/analysis/tabulate-intersection.htm to find the percentage overlap of each census polygon for each county. You'd then join the output table to the census table to get the population attribute for each census area. Create a new field and Field Calculate the percentage overlap * population. The final step would be to summarize the table https://pro.arcgis.com/en/pro-app/latest/tool-reference/analysis/summary-statistics.htm by matching case field (County) and SUM statistic. The assumption in this analysis however is that population is evenly distributed across the census polygons, although it may be a more nuanced approach overall (open to discussion I'm sure).

I would say so, but best to get a second opinion as I get confused regularly by some quirks.

Are these hosted feature services or Feature/Map services? In AGOL, is your site in a collaboration with your internal Portal or is your ArcGIS server public facing and the services added to AGOL? This is important to understanding what is going on. Screenshots would help as I'm not understanding how it is AGOL.

That should be the case yes. It would be worth checking the MXD data sources (MXD that was copied with the service to ArcGIS Server) as the MXD publishing location is not necessarily where the data is referenced from. You can also interrogate the JSON manifest which lists the data source workspaces for the service. I can't remember if this is available through the server manager GUI or you need a script. I have a few scripts to do this I think. Also worth checking through your registered folders and databases in the Server Manager Data Stores tab for possible data locations. Was there any service related data in the ArcGIS Server folder?

On publishing, the data can either be referenced (registered data so0urce in the ArcGIS Server data store tab in server manager) or copied to the server (this is different from a hosted feature). https://enterprise.arcgis.com/en/server/10.3/publish-services/linux/copying-data-to-the-server-automatically-when-publishing.htm#:~:text=To%20help%20make%20your%20data,and%20accessing%20its%20source%20dataset. long story short, in one of the ArcGIS Servers the service was published to, you will likely find the data and a copy of the publishing MXD in a location something like this - <drive>:\arcgisserver\directories\arcgissystem\arcgisinput\<service_name>

Glad it worked out. Can you mark answer as correct if so please.

What does it say when you go to the change owner page? I don't believe the owner is configured in the settings, there's a separate option on the right hand side pane of the group 'change owner'. If not, perhaps there's a SAML and non-SAML account issue with ownership?

It's already a set, and sort() produces a list from the set.

Line 17 doesn't make much sense. the error is probably coming from your search cursor. Are you sure county_name exists in the data rather than being some result of a join on layer object? Are you also sure county_name is the field name rather than an alias?

‎03-14-2023

@Mahdi_Ch I think it would be useful if you explained in the code comments the logic of writing to a set, would be a good thing to understand for beginners.

Please format your code for readability, it's also lost its indentation. https://community.esri.com/t5/python-blog/code-formatting-the-community-version/ba-p/1007633 Do you know what line it's erroring on? that would save a lot of debugging time. Perhaps comment out each section and run it sequentially uncommenting lines to see where the error is. ##what is trail data? Looks like a workspace/folder but you're using it as a clip input? trail_data = r"C:\PythonPro\Trail" arcpy.Clip_analysis(trail_data, county_data, clip_output, where_clause)

Raster Calculator https://pro.arcgis.com/en/pro-app/latest/tool-reference/spatial-analyst/raster-calculator.htm "your raster" * rateConstantValue then creates a new output raster with the cell values multiplied by your constant

Can you screenshot the attribute tables and data type of each table.
