Elevation Attribute Population in Field

CarsonG — Wed, 27 Jan 2021 13:56:35 GMT

Is there a way in field maps to have an attribute for elevation populate automatically after a point has been collected?

I would like the elevation attribute to populate when a feature is newly collected or updated.

When I published the data as a service for use in the field, the data had a vertical coordinate system.

When I try to calculate the Z value in ArcGIS Online using Arcade Calculator using Geometry($feature).z, no results are returned.

If I export the data collected from the field to a GDB, the data has a Z value and can be populated using the calculate geometry tool in ArcMap. The data however no longer has a vertical coordinate system assigned to it.

Hi @CarsonG

With regards to the arcade values for Geometry($feature).z not displaying through ArcGIS Online, are you working with the normal Map Viewer or the Map Viewer Beta?

Although you can generate the arcade expression to display Z values from the feature geometry through the current Map Viewer, you need to use the Map Viewer Beta to actually see the values generated from it.

On a different note, out of curiosity, what GNSS receiver are you working with in the field to capture the features in Field Maps?

Thank you

I am using the current Map Viewer. I will check out the the Viewer Beta.

We are using Trimble TDC600's with a Trimble Catalyst DA1 Antenna.

Thanks!

Hi @CarsonG

Are you also using Trimble Mobile Manager on the TDC600 for the Catalyst receiver to configure the RTK corrections?

If so, when in the GNSS configuration section, did you specify the GNSS output and define a Geoid?

Thank you

CarsonG — Fri, 29 Jan 2021 21:56:33 GMT

Yes, I am using Trimble Mobile Manager. The frame is currently ITRF2014 and Geoid is currently EGM96(Global). This will likely be changing to Frame WGS84 and GEOID18(Conus) for further testing.

Thank you for that information.

When changing the Geoid model to Geoid18 through TMM, I believe the resulting elevations are based off the NAVD88 vertical coordinate system and will be in units of meters.

I have a few more questions:

What is the desired vertical coordinate system defined on the feature service? Is it different from NAVD88 (meters)?
For the configuration of the Trimble Catalyst receiver with Trimble Mobile Manager on the TDC600, just for clarification, you configured the mock location provider on the Android device itself. Is that correct?

Thank you

NAVD88 is what I want as that is the vertical coordinate system from the initial GDB and Features.

Yes, the mock location has been configured and enabled through the developer settings.

Hi @CarsonG

Thank you for that information. Once you've switched to using the Geoid18 model and have captured features in Field Maps, please let me know if the resulting elevations are what's expected.

Also if you're able to view the Z values per the arcade expression through the Map Viewer Beta.

Thank you

-Kevin

Hi @CarsonG

I just wanted to follow-up to see if you've been able to test with the Geoid18 model and if the resulting elevations are expected?

Thank you

Hello Kevin,

I have been working in the field this week and did not want to adjust our current settings. I’ll be able to test next week and will follow up with you as soon as I can. I will test the beta viewer tonight however to determine if the elevation is populating using arcade.

Thanks!

Hi Kevin,

I tried going the route you previously discussed and using arcade to calculate the Z value in the current map viewer. I then switched over to the map viewer beta, the values are blank. Additionally, values that I had in the field before have also been turned to blanks.

Hi @CarsonG

Would you be able to share a copy of your map with me to test out on my end? If so, please share the map/services with a group and invite the ArcGISFieldMaps users into it.

Thank you

-Kevin

Re: Elevation Attribute Population in Field

CarsonG — Tue, 09 Feb 2021 22:15:10 GMT

I will have to create a test set of data to do so. Once I have, I will let you know and share to the the group specified.

Hello Kevin,
I finally have some time to do the testing I wanted to do. I sent an invite to the user specified above. The group is called Elevation Field Maps Testing.

I am going to collect some test points in order to test the Arcade elevation calculation with the Trimble Mobile Manager GNSS output frame set to WGS84 and GEOID set to Geoid18. Additionally, I have created another Location Profile in Field Maps for this testing as follows;

GNSS coordinate System
GCS WGS 1984
4326

Map coordinate system
WGS 1984 Web Mercator Auxiliary Sphere
3857

Thanks!

Hello @KevinBurke

To give an update, I created a web map in which all data is in the same Coordinate System.

WGS 84 UTM Zone 17 N

Trimble Mobile Manager is set to;
Output Frame = WGS1984(current)
GEOID = Geoid18
Field Maps Location Profile is set to;
GCS WGS 1984
4326
Map Coordinate System is set to;
WGS 1984 UTM Zone 17N
32617

After collecting some test points in the field, I attempted to run Arcade and calculate the Z value for the Elevation attribute field. No results were produced. I then opened the map in the Beta Viewer and tried to see if the Z values were displaying. They were not. I know the correct Z value is being collected because when I open the data in ArcPro, I can calculate the Elevation field and produce the correct Z value.

This is not the solution I need, as it would still be beneficial if x, y, and z fields could be calculated on the fly inside Field Maps.

Thank you for the information @CarsonG

Just for clarification, the map includes a point layer that is Z-enabled, however when you attempt to use arcade to calculate the z value into a field using something like geometry($feature).z, nothing is populated. Is that correct?

In ArcGIS Pro, are you using Calculate Geometry to display the Z value?

Would you be able to share that map with me with some test data?

Thank you

-Kevin

Re: Elevation Attribute Population in Field

CarsonG — Tue, 02 Mar 2021 22:46:10 GMT

Yes, the point layer is Z enabled. When I used Arcade to calculate values into the elevation field, nothing is populated. In Pro I used the Calculate Geometry to display a Z value.

I sent an invite to a group called ElevationFieldMapsTesting to the user "ArcGISFieldMaps" you specified previously.

PlutoGIS, I'm having similar issues. Are you still checking this account and if so can I pick your brain?
