Arcade Expression for Geometry in ArcGIS Online Popup

MaryEllen_Perko

Hi. In ArcGIS Online using the web map Attribute Expressions builder, I'm trying to pull feature xy coordinates to show in a popup. In the builder, my code successfully tests with a value; but the value in the popup and layer table is empty. I'm using a map service if that matters.

So, is this code supposed to work? Or am I doing something wrong?

Thanks.

Hi/Hola Braulio Galvez ,

At this moment, only if you have a formula that allows to calculate the coordinates that you want, this is possible. As shown in the examples I shared above: https://community.esri.com/thread/199141-arcade-expression-for-geometry-in-arcgis-online-popup#comment-823702

Hopefully, in the near future there will be support for a transformation engine, or what I have heard, being able to make web requests in Arcade to do this transformation using a REST call and interpret the result. This last feature is something that is on the roadmap, but I don not know the ETA.

Hi Xander Bakker‌, Is possible do the transformation of LatLong to UTM coordinates? Or There is any code in arcade that show coordinates in UTM directly?

Best regards.

Braulio.

Reverse geocoding is not available through Arcade.

i am trying to say i want to include the address of a point in a pop up using arcade(something like reverse geocode to get the address of a point as it is displayed in google map)!! i have a point layer which is editable by the user. When user adds a point i want address be displayed in the popup along with other attribute.

XanderBakker

Yes, you can. You can access the coordinate properties of a geometry and include those in the pop-up using Arcade. See example below:

<SPAN class="keyword token">var</SPAN> geom <SPAN class="operator token">=</SPAN> <SPAN class="token function">Geometry</SPAN><SPAN class="punctuation token">(</SPAN>$feature<SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">;</SPAN>
<SPAN class="keyword token">return</SPAN> <SPAN class="string token">"("</SPAN> <SPAN class="operator token">+</SPAN> <SPAN class="token function">Round</SPAN><SPAN class="punctuation token">(</SPAN>geom<SPAN class="punctuation token">.</SPAN>x<SPAN class="punctuation token">,</SPAN> <SPAN class="number token">3</SPAN><SPAN class="punctuation token">)</SPAN> <SPAN class="operator token">+</SPAN> <SPAN class="string token">", "</SPAN> <SPAN class="operator token">+</SPAN> <SPAN class="token function">Round</SPAN><SPAN class="punctuation token">(</SPAN>geom<SPAN class="punctuation token">.</SPAN>y<SPAN class="punctuation token">,</SPAN> <SPAN class="number token">3</SPAN><SPAN class="punctuation token">)</SPAN> <SPAN class="operator token">+</SPAN> <SPAN class="string token">")"</SPAN><SPAN class="punctuation token">;</SPAN><SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

Is there a way to display the location of a point in pop up using the arcade or any other way to add location in pop up along with other attributes that i get from arcade expression??

XanderBakker

In case you need the coordinates in WGS 1984, I have a couple of posts that show an example of how you can convert Web Mercator coords to WGS 1984. This might be useful in case you need to create a hyperlink to Streetview or Waze or send the coordinates to prefill a Survey123 form.

Examples (in Spanish) can be found here:

How can i get de X and Y point from my feature in the coordenate system from the rest url?

I need to create a custom expression to put it on the popup window with this info.

the Geoametry function retorns only in web mercator.

XanderBakker

For multipoint geometry you may want to try this:

<SPAN class="keyword token">return</SPAN> <SPAN class="token function">Round</SPAN><SPAN class="punctuation token">(</SPAN><SPAN class="token function">Geometry</SPAN><SPAN class="punctuation token">(</SPAN>$feature<SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">.</SPAN>points<SPAN class="punctuation token">[</SPAN><SPAN class="number token">0</SPAN><SPAN class="punctuation token">]</SPAN><SPAN class="punctuation token">.</SPAN>X<SPAN class="punctuation token">,</SPAN> <SPAN class="number token">2</SPAN><SPAN class="punctuation token">)</SPAN>‍<SPAN class="line-numbers-rows"><SPAN>‍</SPAN></SPAN>

and:

<SPAN class="keyword token">return</SPAN> <SPAN class="token function">Round</SPAN><SPAN class="punctuation token">(</SPAN><SPAN class="token function">Geometry</SPAN><SPAN class="punctuation token">(</SPAN>$feature<SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">.</SPAN>points<SPAN class="punctuation token">[</SPAN><SPAN class="number token">0</SPAN><SPAN class="punctuation token">]</SPAN><SPAN class="punctuation token">.</SPAN>Y<SPAN class="punctuation token">,</SPAN> <SPAN class="number token">2</SPAN><SPAN class="punctuation token">)</SPAN>‍<SPAN class="line-numbers-rows"><SPAN>‍</SPAN></SPAN>

... since it is a collection of points although each multipoint only has a single point (as far as I could see from a query on your REST service)

Thanks everyone for the help so far. I do see the code works with map services. The field in the table won't always populate (for me anyway) so I didn't catch that it worked in the popup.

I think the problem is with the map service I started with. I haven't figure out why, yet, but it appears that the "point" feature-type layer loaded via the map service is really a "multipoint" layer/feature class. For some reason the point-related arcade expression code works with the layer in the expression builder, but perhaps not outside of the builder. I'm looking more closely at our map service and the map viewer.

If anyone would like to take a closer look, here's the map service: NCDOT_STIP (MapServer)

Thanks again. I really appreciate the help.

I also tried this using this map service: Hurricanes (MapServer)

It worked as well.

XanderBakker

I used a hosted feature service.

MaryEllen_Perko

Thanks for the help so far. Are you using map services or feature layers/services?

Thanks.

kenbuja

This function seems to work properly.

Text(Geometry($feature).x);

and returns this in the popup

Have you checked the popup configuration to see if it's displaying the custom expression?

XanderBakker

Not sure what might be going wrong in your case. I just configured something similar and it works.

I entered the pop-up settings and added two expressions:

and the result is displayed:
