Extract Data by Intersection

deleted-user-iwYtitJHBIyn — Tue, 28 Feb 2017 00:15:20 GMT

Hello,

I have two distinct layers; one containing polygons representing HOA boundary limits and another featuring our City Parcels. Is there a widget (or method for that matter) that I can use to obtain all Parcels intersecting a selected HOA in ArcGIS Online? I know I can use the select tool but I was hoping to utilize something very similar to the Intersect function in ArcGIS Desktop.

Many thanks in advance.

Jeff

Jeff,

The eSearch widget allows for this but you would have to use WAB Dev. edition.

That would be fine Robert.

Do you have a link to this widget?

Thanks.

We are running WAB 2.2. Is there an Enhanced Search Widget for that version?

Jeff,

I would try 2.3 and if it does not work then I can provide the 2.2 version.

Hi Robert,

I am in the process of configuring the Enhanced Search Widget and ran into some difficulty.

I am at the Add a Search Layer phase.

For the Search URL I am assuming the information necessary for this field should correspond to the "right click map service/Service Properties/Mapping/REST URL that is listed. Unfortunately, it does not seem to like that path and supplies the following error message - "Search URL Field Required, Included Fields is Empty"

Am I correct in my assumption of where to obtain the correct path?

Thanks.

Jeff

Jeff,

The url need to contain a full url that even specifies the layer inside the map service:

http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Louisville/LOJIC_LandRecords_Louisville/MapServer/2

(notice the /2 at the end of the url).

Brace yourself for "stupid" questions Robert...please bare with me.

Is the "2" in your URL corresponding to the order of the layer in the legend list?

Jeff,

The layer ID is a zero base ID of the layer order in the map service. So 2 would be the third layer (the IDs include groups as well as actual layers).

Perfect. That worked! Thank you, Robert.

Hi Robert,

I have configured a search expression to search by HOA Name using Unique. That way users can select the name from the drop down within the application. There are 161 locations.

When I open the application the HOA Name search is already attempting to Retrieve Unique values but it just keeps cycling and cycling and never populates the drop down with the table values.

What am I doing wrong?

Jeff,

How many thousands of records do you have in the layer?

Re: Extract Data by Intersection

deleted-user-iwYtitJHBIyn — Wed, 08 Mar 2017 20:10:45 GMT

Robert,

Only 161 records in the attribute table.

Jeff,

Can you check the browsers console and see if there are any errors listed there?

Yes. Please see the following:

Jeff,

Unfortunately that is not helpful. If you do not select unique value can you get the widget to complete a query successfully?

Re: Extract Data by Intersection

deleted-user-iwYtitJHBIyn — Wed, 08 Mar 2017 23:52:44 GMT

Robert,

Yes. If I change it to "Ask for Values" it completes the query successfully.

For Unique...I have just the Unique button enabled, nothing for "Ask for Values", nothing enabled for "Value is required to be entered to enable search", and the SQL statement reads "HOA_Name = ''

It was cycling before...now it doesn't search at all.

I'm mystified.

Robert,

I should actually add that the individual HOA Names are not showing up in the drop down. It's completely blank. Almost like the query doesn't understand where to get the data for "Unique".
