Hi everyone,

What's the best way to figure out which maps use which layers or which apps use which maps?

Thanks!

I haven't used it, but allegedly you can do this in ArcGIS Knowledge (https://pro.arcgis.com/en/pro-app/latest/help/data/knowledge/get-started-with-arcgis-knowledge.htm). At the ESRI Midwest UC this year they mentioned that Knowledge can be used this way multiple times...

Thanks for sharing Stephen! I've looked and don't see an example of how to use it with AGOL. Documentation seems to only refer to Enterprise. When I try creating a new investigation, the option is actually grayed out, probably because my active portal is AGOL and not Enterprise. Did they say that it works with AGOL too? I've never used ArcGIS Knowledge, so it also very well could be user error.

Hmmm, good point. When I've seen ESRI talk about ArcGIS Knowledge they didn't get into the weeds too much, so I'm not sure. However, doing the same documentation dig you did it does seem to be Enterprise-only. Sorry.

For AGOL content I think one could write a Notebook script that listed all items, and then listed each data item that an item uses (I used the word "item" in that sentence a lot...). Basically, the Python API might be capable of creating a report sort of like this:

MyWebMap
- Data item 1
- Data item 2
- Data item 3

MyOtherWebMap
- Data item 1
- Data item 4
- Data item 3
- Data item 5

Then you could use pivot tables to list all the web maps that use, for example "Data item 1"

That might be possible?

Thanks Stephen! I'll look into the Python API. I haven't used that one before, so this will be a good experience.

I've had to piece together something in past since the dependencies_to/from are only Enterprise specific.

I started with this script from Esri forums and then just made some tweaks based on what I need:
