ArcGIS Collector auto-populate long/lat, length, acres

BobWheeler

Trying to figure out how to configure features so that Collector will auto-populate columns such as Longitude/Latitude (points) and Acres for polygons. I need end users to be able to pull this information back up without my having to post-populate these columns.

Bob, this doesn't solve your problem but I had a similar issue which might shed light on your question. I have a workflow where I would like the shape area to be autopopulated in either Collector or ArcGIS Online. I posted a question to the ArcGIS Online threads and received a response that it was not possible without custom development, the off the shelf tools do not currently allow for it. It would be great if it is possible and I will pay attention to this thread in case someone has another suggestion. Good luck!

Hello Ben - it appears as you stated - this cannot be accomplished out of the box but is on esri's radar. doesn't sound like it is in the 10.3 release of collector though so again back to the waiting game. Will have to see if posted out on esri ideas site and promote or add.

It's been a couple of years now since this was first posted. Has anyone found a way to do this yet? I am also very interested in auto-populating lat/long fields when I drop a point in Collector. Alternatively, can anyone suggest resources for where to start if I were to do this with some custom development? Ultimately I want to populate the lat/long in Collector so that I can pass these attributes to Survey123.

This will work if you're using an external gps receiver like a trimble R1, but I still haven't found a way to auto-populate a lat/long field using collector automatically using only a cellphone GPS on android or iOS: GitHub - Esri/collector-tools: A set of python scripts and geoprocessing tools to automate common tasks and workflows in…

BobWheeler

here is something we implemented - created

Attribute Field Alias Field Name Field Type

ESRIGNSS_LATITUDE Latitude Double

ESRIGNSS_LONGITUDE Longitude Double

These will auto-populate with the Latitude/Longitude when using Collector.

This worked like a charm! Love this!

I am wondering though, how does this work? It works awesome and extremely happy with the results but I don't understand how it automatically calculates. Clearly, some background work being done. But how? I would appreciate some clarification

Kylie

Hi Siona -- Collector automatically records some metadata for GPS, and those are among the ones that are recorded. You can learn more about this here: Prepare for high-accuracy data collection—Collector for ArcGIS | ArcGIS

Be aware that lat/long will only be captured if you use GPS to collect the location of your feature. If you drop a pin, they'll be left blank.

Some time has past since this original post and the solution by Bob Wheeler worked great! But now I am trying to use the same workflow to auto populate Lat & Long in Collector for ArcGIS instead of, what is now called, Collector Classic. My issue is that I cant get the Lat & Long fields to auto populate anymore by using the solution from Bob Wheeler in the new version of Collector. Bob Wheeler have you run into this same issue? Kylie Donia do you know if the new version of Collector has some other means of autopopulation?

Thanks in advance!

Hi Siona -- Are you using the new Collector on iOS or Android?

Anonymous User

I am using the new Collector on iOS. But eventually I would like the process to work on both iOS and Android. Thanks!

Kylie

This is working in Collector on iOS today (and coming to Android in a later beta release). I just tried it by making a point layer with the ESRIGNSS_LATITUDE and ESRIGNSS_LONGITUDE fields, and when I used the GPS in Collector to add a point, it recorded Lat/Long into those fields. Siona Roberts‌ can you make sure you are using the GPS when you collect (and not panning the map and clicking "Update point")? If you are, please make sure the fields in your layer match the required names shown here.

Only works in Aurora builds but you can use Arcade to calc the lat long. I have also done distance in a 123 form. Have not done area yet.

I have the Auto-populate of Lats and Longs working, but it only populates in Decimal Degree, is there any way of showing the results in the fields in Degree, decimal minutes?

ILIAMARTASHVILI

It records only when working with GPS. Is it possible to record the coordinates without using GPS, for example when moving a point to another location on the map?

EmmaSchultz1

I agree with your ask. I have a team of drone pilots who either complete their flight location documentation with Field Maps before they arrive to the site OR at the site. The GPS solution obviously only works if they are already at the site location. The inability to auto calculate the Lat/Long from WGS84 basemaps when adding a point prevents our pilots from pre-planning the flight at the office. All must be done in the field.
