I have two polygon layers in ArcGIS Online (for organizations) stored as Feature Layers; one is population block, another is the AOI polygon. They are overlapping and I want to find out what portion of the population is "located" within the AOI polygon.

enter image description here

I used to do that in ArcGIS Desktop by creating a Feature Layer with Use Ratio Policy option with Make Feature Layer GP tool and then running Intersect GP tool (which will respect the field ratio settings). An easy thing.

I cannot find a way to do this in ArcGIS Online though. Overlay with Intersect method doesn't split the attribute value; Summarize Within doesn't clip the area and of course no value splitting either. Which tool/workflow should I use?


I don't have a specific example, just a couple of suggestions- couldn't you do this with 'summarize within':


...more specifically documented here, and although I haven't tested, it seems you could make use of 'percentShape' after specifying 'groupbyfield' (not sure if you already tried that):


Otherwise, as a workaround, download to a temp gdb and proceed as you've already specified with a feature layer ratio.

  • Got it working with Summarize within. I should have missed some option when running the tool earlier. Now it works splitting the attribute. – Alex Tereshenkov Jun 2 '15 at 15:22
