Hi, We have custom LocationDataSource implementations in our app, in addition to using the NmeaLocationData source for connecting various devices for external high accuracy GPS on iOS.  These devices will also provide an app which is used to connect to an RTK server for corrections. I am trying to understand how one applies a datum shift in these cases. What I am trying to do in our custom LocationDataSource is basically project my Wgs84 point still using Wgs84 but applying a GeographicTransformation, prior to sending the point to UpdateLocation var sr = SpatialReferences.Wgs84; MapPoint mp = new MapPoint(longitude, latitude, sr); var geoStep = new GeographicTransformationStep(108363); GeographicTransformation geoTransform = new GeographicTransformation(geoStep); mp = (MapPoint)GeometryEngine.Project(mp, sr, geoTransform);   With the NmeaLocationDataSource I do not know how you would necessary apply the datum shift, until you saved the point. The problem is we don't seem to be coincident when comparing to Field Maps using the same datum shift.  So I am trying to understand if there is a different way this could be done.   The offset is consistent, about 3 feet.   We really need the two apps to be the same because a group within the company uses Field Maps and they may come to locate the assets at a later date ...

I find the documentation a bit confusing on this topic. Is it possible to implement an HA Enterprise deployment using only Web Adapter and not a 3rd party load balancer?  If so where is documentation for this  @JonathanQuinn  Personally, I do not see how Web Adapter is setup in front of two Portal machines. ...

We are wanting to change some offline WebMaps to use SubtypeFeatureLayer.  A main driver behind this is that it allows us to edit domains in AGOL.  It also is a better general fit with the Utility Network configuration. A big issue making this much more complex is that when you retrieve the LegendInfo objects from SubtypeSublayer these do not have a Name associated to them.  There is no way to identify what a LegendInfo is.  This seems to me to be a bit of a bug, as there is no way to identify what a LegendInfo is unless you somehow know what SubtypeSublayer it was created from.  But it makes it impossible to use the code which already assumed the LegendInfo would have an associated Name (matching the Subtype). Making this issue even more difficult is that LegendInfo is a sealed class.  So it is not even possible to make a subclass and assign a Name that way. This has made, what seemed to me should be a trivial operation into a really complex refactoring because there is no way to pass along the IReadOnly<LegendInfo> collection as the previous code did. This is using Runtime 100.15 ... View more

We have an application that places a Tee and an attached service line (in gas) in a UN.  That part seems to work as expected.  The problem is trying to validate the topology afterwards. This seems like a pretty simple task simply call ValidateNetworkTopology Method  According to documentation this should not be wrapped in an edit operation.  Unfortunately this does not seem to work.  If I try this way, to first expand the envelope public ValidationResult ValidateTopology(UtilityNetwork utilityNetwork, Geometry serviceGeometry) { //expand the area used for validation Envelope envelope = serviceGeometry.Extent.Expand(1.05, 1.05, true); ValidationResult result = utilityNetwork.ValidateNetworkTopology(envelope); } The following exception is received ArcGIS.Core.Data.GeodatabaseEnterpriseException: The specified coordinate exceeds the valid coordinate range. ---> System.Runtime.InteropServices.COMException: Exception from HRESULT: 0x80041590 at ArcGIS.Core.Internal.IUtilityNetworkIOP.UtilityNetwork_ValidateNetworkTopology(IntPtr utilityNetworkHandle, IntPtr extentHandle, Boolean useAsynchronousService, DateTime& timeStamp, Boolean& hasErrors, Int32& dirtyAreasCount, Boolean& isFullUpdate) at ArcGIS.Core.Data.UtilityNetwork.UtilityNetwork.ValidateNetworkTopologyInternal(Geometry extent, InvocationTarget invocationTarget) --- End of inner exception stack trace --- If instead of using the slightly expanded envelope, the service line geometry is sent the method simply times out.  No exception is received Seems pretty straight forward, not sure what is incorrect  Thanks   ...

We use a data model with a strong emphasis on subtype based domains.  For those familiar with the Utility Network know this approach is used a great deal. When these layers are published to AGOL the definitions of the subtype based domains are loaded to the service and the service definition reflects these.  The problem is, the UI in AGOL does not support editing or viewing these subtype based domains. My question...does anyone know of a way to modify these domains.  About the only thing I can think of would be to write a tool that does this with the REST API, which is no small undertaking Thanks ...
