Survey123 Mobile App Truncating Number Fields?

KevinThompson — Tue, 23 Apr 2019 18:14:12 GMT

Hello All,

I have been experiencing an issue when bringing in the coordinates from Collector into Survey123. Within the feature service the data is stored correctly. When I try and display the coordinates within a note or a decimal within survey123 the coordinates are truncated within the mobile app on a mobile device compared to viewing it on the mobile app installed on the computer. Any cause for this or a work around?

I have tried storing it as a string and performing calculations with the number

Thanks!!

Hi Kevin,

It sounds as though the problem is with the url that Collector is creating on the device is rounded to 2 decimal places. Can you confirm in Collector for those 2 fields in the pop-up that you see all the decimals? If not this coudl be the cause of the problem. Modify the pop-up in the webmap to include all the decimals, not just rounded to 2 places.

If you look at the url in your first screenshot above on Windows, the lat and lon variables have all the decimals, so this is what is passed into Survey123 and it shows correctly. My guess is that if you could see the url on the device that Collector generates, it is rounded in the url already from Collector.

Phil.

Good Morning Phil,

Thank you for taking the time to help me with this. I have checked the Webmap and the pop config was truncating the numbers! I assume I have reached another limitation as I can only have a maximum of 8 digits through the attribute config? As you can see below the coordinates have more than 8 decimal places

Hi Phil,

I am having this issue with any form while using a phone. On our web app survey form accessed via computer, it brings all 7 decimal points. We have configured all our pop-ups and ensured the tables and original feature layer has all the decimal points. Has anyone figured out how to keep the phone URL from truncating decimals. It's causing our points to be inaccurate.

Thanks!

Marisa

Hi Marisa,

Can you provide more information about the workflow? Are you using Collector or another app to launch the URL? Are you using the field app or web app to open the survey?

Can you provide what versions of the apps you are using, what devices and OS versions, and also the survey and URL link would be helpful?

Phil.

Hi Phil,

Right now Marisa and I are pulling our coordinates from a hosted feature layer. In our web map, the popup from the established point contains a link to the survey (both the web app version and the mobile app) and carries over the name, address, and coordinates. When the survey is opened up on a computer, the coordinates carry over fully... all 6 decimals. When the survey is opened on a phone, android and iphone, only 3 decimals carry over in both the web app and the mobile app. The pop ups are also configured to allow up to 8 decimals but that doesn't seem to help.

Hi Katie,

What application are you opening the link on the phone with?

Hi James,

We created a web map using AGOL with a feature service that had pop-ups where the user could select either the web survey or the app survey to prepopulate fields in a new feature service. When using the phone both link options shorten the coordinates to 3 decimal places regardless of it is the web form or the app. On a computer the web form correctly brings all decimal places without shortening coordinates.

Hi Marisa,

If you are using the ArcGIS Online Map Viewer on the phone, could you copy the hyperlink and paste it into a text document? If so, does the link have expected values for lat/lon or truncated values?

Hi Marisa,

Thanks for trying that out - it looks like the truncation is happening in the mobile version of the web page. We'll try to replicate and file an issue with the appropriate team.

Pretty sure I had the same issue a few minutes ago, until i realized that the Custom URL works differently when initiating from the Web Map vs Collector.

In the web map it appears that the Custom URL does not honor the Source Layer Custom Pop-up values. But when pushing the URL from Collector the Custom Pop-up settings truncate the X/Y value to the decimal settings from the Source Feature class.

By changing the SOURCE layer Custom Pop-up on the web map which defaults decimals to 2 decimal places to 8 decimal places. The Custom URL being pushed from collector now pushes the right # of values in the URL to survey123.

I went about setting the DESTINATION feature class CUSTOM pop-up to 8 decimal places, but honestly that layer is not being written too until the Survey is submitted. Still needs to set the Custom pop-up in both Source and Destination feature classes to 8 decimals to display and push data correctly on the mobile data.

Bonus fun fact if your USING ArcGIS Explorer to push a custom URL, the values with coded domains actually PUSH the LABEL and not the CODE. Meaning if you had integer fields

1 = Cast Iron

The URL Will push the word "Cast Iron" from Explorer

While in Collector it will push the proper coded domain 1.

So the CUSTOM URL function differently on each platform, Web and Mobile Apps. So just FYI.

All:

I have been experiencing the same issues described in this thread: trying to create an attribute expression that calculates lat/long coordinates from a hosted feature layer, then integrate Field Maps with Survey123 to open a form and have the geopoint plot the submitted survey on top of the feature using the result of the attribute expression using a custom URL via the custom URL popup (&center=).

I have been using the below formula, which is called out in a multitude of other posts on the community page and it was correctly calculating the coordinates in ArcGIS Online Web Viewer Classic, but then when we tested this functionality in the field, the point was not mapping:

var originShift = 2.0 * PI * 6378137.0 / 2.0;

var lon = (Geometry($feature).x / originShift) * 180.0;
var lat = (Geometry($feature).y / originShift) * 180.0;

lat = 180.0 / PI * (2.0 * Atan( Exp( lat * PI / 180.0)) - PI / 2.0);
return [lat, lon];

I found that this formula results in an Array data type, with associated brackets. These brackets do not show up in ArcGIS Online, but when you view the popup in Field Maps, you can see the brackets. So because of this, i tested further and in the original function, i removed the brackets in the return line, which worked but was not perfect. It was not perfect because the coordinate results ended up being truncated to 2 decimals, and even though the submitted form was executing, the point was being plotted hundred of feet away.

After 10 hours of testing and researching these threads (which by the way, all of the contributions are EXPONENTIALLY HELPFUL AND I AM SO GRATEFUL OF YOUR KNOWLEDGE) i was able to find the CORRECT SOLUTION:

1.) Create an attribute expression for latitude:

var lat;
var originShift = 2.0 * PI * 6378137.0 / 2.0;

lat = number(Geometry($feature).y / originShift) * 180.0;
lat = 180.0 / PI * (2.0 * Atan( Exp( lat * PI / 180.0)) - PI / 2.0);
return lat;

2.) Create an attribute expression for longitude:

var lon;
var originShift = 2.0 * PI * 6378137.0 / 2.0;

lon = number(Geometry($feature).x / originShift) * 180.0;
return lon;

3.) Because of the "number" identifier, In ArcGIS Online Web Map Viewer Classic go to Configure Popups, make sure your pop up display is custom, then the important step is to click Configure Attributes. Navigate to the newly created expressions and expand the decimal places to a minimum of 5.

4.) Lastly, in the custom URL make the "&center={expression/expr3},{expression/expr4} where expr 3 is Lat and expr 4 is Long.

I have been testing since i discovered this and it has been running smoothly. Happy Mapping!
