Beta version of the enhanced Water Utility Isolation Trace 

To the ArcGIS users that have implemented the Water Utility Isolation Trace, thanks for your feedback!  We know that your organizations love the Isolation Trace and we need to simplify the process of using your data with the Trace and make the Trace run faster. 

Well…. Voilà! 

Available now is a new Beta version of an enhanced Water Utility Isolation Trace that is both easier for you to configure with your data and also returns results faster. 

When you dive into the Beta you’ll notice some big differences between the Beta and the currently released version. 

The Beta is not set up to run out of the box with an Esri specified schema.  Now you use the Generate Isolation Trace Toolbox script to specify your geometric network and all the required parameters for the process.  


A variable number of snapping layers, trace disabling layers, and trace result layers are also defined here.



This information is used to create a new Python toolbox with the Isolation Trace script, which replaces the model in the current version. 



All you need to do now is run the Isolation Trace script and publish the results to ArcGIS Server.  We have learned a lot and below are the best practices for publishing this script. 

1:  Start with a brand new Map Document.  Add just the water mains layer to the map. 

2:  Open the Isolation Trace script and add a Flag on a water main. 

3:  Once the script completes, remove the water mains from the map, so only the trace results remain in the table of contents. 

4:  If you want to reference the geodatabase that you specified in the Generate Tool script, add that parent folder of that geodatabase, or the connection to the geodatabase to the ArcGIS Server Data Store settings. 

5:  Open the geoprocessing Results windows and share as a Geoprocessing Service. 

6:  Change the name of the inputs and outputs, as these are what is used by the widget. 

7:  Configure the widget. 

Now we need your help. Try the Beta Enhanced Water Utility Isolation Trace today and let us know what you think! Pending feedback, we anticipate releasing the Enhanced Water Utility Isolation Trace in Q1 2017.
