Use selected features as input to analysis tool

LarsElmkær_Chwastek

Hi all,

I have a question about using selected features in an analysis tool. I can't quite figure out how to make this work.

If I use the select tool to select let's say 10 houses from a building layer, I want to be able to take that building layer and use as an input to for instance the buffer tool..

But when I do that, it doesn't honor the selection.. it just takes all the features in the layer..

It would also be cool to be able to do the same with a GP/Web tool that you publish your self

Do anyone know a solution?

Yes, it will be available in upcoming 11.4

Sorry for late response. But this scenario is achievable now.
You can now select features in other widgets (map, table, list etc.), or select use Select widget. Then for the selections there is a data action called "Set as input of Analysis" which can pass the selections to analysis tools. Please check:

Hi @LarsElmkær_Chwastek

Unfortunately "selection" is not yet supported in current Analysis widget. But we are working on that!

I have achieved a rough workflow where my custom web tool relies on a selection of a feature to append to another feature.

Is a possible to use in an instance where 1. when a selection is made 2. the Analysis tool already understands there is a selection being made?

The alternative, is the user selects the features from the feature widget, then 'Set as Analysis input', then go to the analysis widget and set up the rest of the parameters.].

Wei_Ying

It is a known limitation if you use Select widget to pass as input as Select widget laze load the data.
A work around is add a Table widget to load all the attributes you need and use the same data action "Set as analysis input" from the table after you made selections

Yes we have found that some ways it works and some ways it does not. Super confusing to the user.

I have not made a breakdown of each of the different ways yet.

I got this working in AGOL, maybe my reply to OP above will help, I was stuck on this for a few days

Not sure if it was just updated, but I had this issue until I realized I needed to use the action button on the selection widget to set the selection as the input for the GP tool, NOT the select layer button on the GP tool in the analysis widget. Also, the input is received as a "RecordSet" object, (parameter should still be set to "featureSet"), I'm still working on parsing the RecordSet, my next try is to dump the JSON into a python dictionary to access the feature attributes, but like the comment below, I only get the first few attributes, so I guess I'll be collecting the OIDs to query from my hosted layer in a query.

Hello all

We use the solution here to send some selected features to gp service.

The gp service gets the features but it looks like it does not gets all the attributes of each feature, only 2-3 attributes are send as part of the feature set.

Is that a bug?

Thanks

Correct it is ignoring the selection which was a very weird thing to leave out. It has us at a standstill on converting now. Last I heard it was "coming soon" but I still do not see it working.

Hi Everyone, I am having a lot of trouble with this and am hoping someone can point me to a tutorial? I am trying to create a simple custom tool in AGOL that will take a selection from ExB. I am currently trying to process it as a FeatureSet. I am currently attempting to do it by selecting a default input parameter of type FeatureSet. When I add it to ExB and also add a select widget (with Set as Analysis input using "Analysis") it doesn't seem to change the "Count of Features" when I change the Selection. What should I be seeing? Is there a tutorial for either an established Analysis tool or a custom one?

Wei_Ying

That's weird. I cannot reproduce based on your description. I guess it might be tool specific or data specific.
I suggest you to contact Esri Support to provide us a repro case. Appreciated!

GFlonk

Yes it is, though my account has access to it. I think what would help here is a simple step by step doing only the necessary to verify that in experience builder; we can add a table with data, and send its selection to a webtool, then in the webtool verify we receive a selection (only by printing or something). If i have that i can verify that flow works and could be a possible solution for clients i have. I tried doing exactly this myself and ran into the error i mentioned earlier.

Wei_Ying

Hi @GFlonk , I guess the data you used as input is a private feature service hosted in some portal?

Wei_Ying

The selection processing is available in ArcGIS Online, and for Enterprise, it is available in 11.4.

GFlonk

Oh yeah I didn't specify; I tried this on ArcGIS Online.

dougbrowning

No the GP widget does not respect selections at all yet. Which is super weird to release it without that. No one runs a tool on an entire FC.

See farther up this post there is a hack posted.

I created a simple webtool today to test this functionality in Experience builder, and it doesn't seem to work in my case. I want to create a webtool that works with a sleection of records as input. For this I created a simple notebook with one parameter and published it as a webtool.

Then created a basic experience with just a table and the analysis widget. When i try to set the analysis tool input from the selection in the table I get this message:

When i look in the console we see this error:

Am i doing something wrong or am i encountering a bug?

dougbrowning

Just ran into this today. Really need it. thanks

LarsElmkær_Chwastek

Thank you for the update Wei Ying, have a great weekend 🙂

Wei_Ying

Yes, it will be available in upcoming 11.4

LarsElmkær_Chwastek

Hi Wei Ying,

Thank you for your response and no worries 🙂

Just to be 100% clear - the Set as input of Analysis option is not available on Enterprise yet? Not until 11.4 or??

LarsElmkær_Chwastek

Hi WeiYing,

Thank you for providing an answer and the update. Do you have any idea on when it could potentially be ready?

Thanks 🙂

Thanks for your answer Daniel, although not what I had hoped for 🙂

I have added the idea to the community: https://community.esri.com/t5/arcgis-experience-builder-ideas/use-selected-features-as-input-in-analysis-tools/idi-p/1397177/jump-to/first-unread-message

The "Select" options gets me a bit of the way at least with the buffer tool.

Thanks

Hi @LarsElmkær_Chwastek

At the moment I don't think that this functionality is possible, but I think that this would be an excellent to put into the Esri Ideas community.

I have tried to make the two widgets work together but I cannot find a way to link them either. There are options in the select widget to make a buffer using the spatial interaction, the yellow circle outlined is the buffer created. The settings on the right-hand side are for the select widget.
