Search for features within a polygon boundary

ElizabethBrumfield — Mon, 09 Oct 2017 20:31:41 GMT

I am trying to build an app using the Information Lookup template. I have two layers - one is parcels and the other layer is larger polygons made up of groups of those parcels. I would like the user to be able to search for a larger polygon and then be able to click on each individual parcel and get info on each clicked feature as well as the larger polygon. I have tried the WAB, basic viewer template, and Information Lookup template but nothing will allow me to search on the larger polygon and then click on the smaller polygons to get their information. Does anyone have any ideas? Thanks in advance.

I suppose that on the data you could enable a relationshipclass between the larger polygon and the individual parcels, which would enable to click on a larger polygon and in the pop-up the relationship would enable access to the individual parcels.

Also if you enable a search on the layer with the larger polygons and it zooms in to the larger polygon, you could still click on the smaller ones.

Ok I'll try setting a relationship. But I did your option 2 - enabled a search on larger polygons and then trying to click on the smaller ones. In the Information Lookup template it only works if I set the smaller polygon to be a lookup layer, too - but then when user searches for a larger polygon they get the entire list of smaller ones.

Thanks, I'll try your first suggestion.

Can you share some screenshots of what is happening at this moment to get a better idea of what you have right now and what is not working for you?

I'm sorry I haven't responded, I've been out sick for the past week. Maybe looking at my app would be more helpful to you than a screenshot. Here's the url: Information Lookup . Just start typing something like "Abernathy" and choose the MSBU that auto fills. I want the app to zoom to the MSBU (the larger polygon), and then the user can click on a parcel and get information about that parcel. I swear I thought I had it working that way a few weeks ago but somehow I lost my thread and now it only shows MSBUs (larger parcels). Thank you in advance!

I guess it should be looking at the other (parcel) layer when you click on a parcel. Although each time it centers, only the information from the MSBU is returned. Can you share the configuration of the app?

Yes, when a user clicks on a parcel inside the MSBU polygon, their parcel data should appear. Here are the lookup layer and search tabs from my app. I have experimented with all different combinations of both. I either end up with showing all the parcels in a MSBU (too busy), or like I have it now - nothing showing.

How is the pop-up defined?

Re: Search for features within a polygon boundary

On the parcel layer, I have set the display to be "A List of Field Attributes" with the owner name and parcel number showing. On the MSBU layer I also have it set to be a list of attributes - with MSBU name, ID#, starting year, ending year, duration.

I will have to dive into the template and see what is being used, but I might be something with the order of your layers in the web map or the configuration of the pop up information.

OK, thank you! I'll take a closer look at my layer order and popup for now.

Ok, I've made some headway by setting the lookup layer to be MSBUs and MSBU parcels, then setting the search by layer to be MSBU Parcels, Then setting the search to be MSBUs. The only issue with that config is the first time the user searches on a MSBU, a parcel is also highlighted. (I think the one with the lowest ObjectID).

And what if you only let them search for MSBU? Or is it a necessity to search on parcel too?

Re: Search for features within a polygon boundary

ElizabethBrumfield — Mon, 23 Oct 2017 20:31:34 GMT

The way I was thinking the app would be, the user would type in the MSBU name - Our parcel numbers are so long and convoluted most people don't know their own number. I suppose they could use their address too so I should add the ESRI World Geocoder.

Re: Search for features within a polygon boundary

XanderBakker — Mon, 23 Oct 2017 23:05:35 GMT

Sounds logical. Find by MSBU name and than search visually on the map or search parcel directly by address. I still need to do some tests to see if I can reproduce the problem you have.

Thank you. So you are able to search on it the way I'm envisioning? In that case it must be something with my app configuration?

Hi Elizabeth Brumfield ,

Sorry for the delay, but as far as I understand, the Lookup Layers setting will define which layer information will be displayed. At this moment from the screenshots I notice that your MSBYParcels is switched off:

For instance in my case I have 2 layers defined:

... and when I search I get the information of both layers back:

Yes, I see that - but see how that give you the list of all the manzanas? I don't want to show the individual features until the user clicks on them. I think I've got it working now, though. Thank you for your help!
