Introduction<\/h1>\n

In our previous articles, we discussed how to use ArcGIS Pro and the Gas and Pipeline Referencing Utility Network Foundation<\/a> to create, manage, and validate subnetworks. If you haven’t read the previous articles yet, I strongly recommend you go back and read part one<\/a> and part two<\/a> as they introduce key concepts and techniques you’ll need to know to understand this article. You can find all these articles, and more, in the ArcGIS Utility Network for Gas and Pipeline reading list<\/a>.<\/p>\n

In addition to managing errors reported by the application, we can use several other techniques that leverage the ArcGIS Utility Network and ArcGIS Pro capabilities as part of our data quality assurance program. These techniques allow us to find features that indicate there are data quality issues in an area that require a user to review. Every utility has its own set of business rules and quality assurance checks that they perform, and hopefully, you can incorporate the techniques discussed in this blog into your processes going forward. The following diagram provides an example of customers’ basic quality assurance process to log, review, and resolve issues.<\/p>\n"},{"acf_fc_layout":"image","image":{"ID":1740912,"id":1740912,"title":"Quality assurance process","filename":"Quality-assurance-process.png","filesize":16241,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/10\/Quality-assurance-process.png","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/utility-network\/electric-gas\/gas-quality-assurance\/quality-assurance-process-2","alt":"","author":"304562","description":"","caption":"Quality assurance process","name":"quality-assurance-process-2","status":"inherit","uploaded_to":1740872,"date":"2022-10-21 14:50:43","modified":"2022-10-21 14:50:49","menu_order":0,"mime_type":"image\/png","type":"image","subtype":"png","icon":"https:\/\/www.esri.com\/arcgis-blog\/wp-includes\/images\/media\/default.png","width":624,"height":191,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/10\/Quality-assurance-process-213x191.png","thumbnail-width":213,"thumbnail-height":191,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/10\/Quality-assurance-process.png","medium-width":464,"medium-height":142,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/10\/Quality-assurance-process.png","medium_large-width":624,"medium_large-height":191,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/10\/Quality-assurance-process.png","large-width":624,"large-height":191,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/10\/Quality-assurance-process.png","1536x1536-width":624,"1536x1536-height":191,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/10\/Quality-assurance-process.png","2048x2048-width":624,"2048x2048-height":191,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/10\/Quality-assurance-process.png","card_image-width":624,"card_image-height":191,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/10\/Quality-assurance-process.png","wide_image-width":624,"wide_image-height":191}},"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"

Many of these quality assurance checks require that subnetwork names are populated. If you read our previous blog<\/a>, you will remember that this field is populated when you run the update subnetwork tool. Because of this requirement, an important part of the quality assurance workflow is to run validate topology and update subnetwork to ensure all your subnetworks are error free before you begin!<\/p>\n"},{"acf_fc_layout":"content","content":"

Unknown Pressure Zone Subnetwork<\/h2>\n

In the gas model, every feature that belongs to a pressure zone should also belong to a system. Common exceptions to this rule can include lines between system controllers and pressure zone controllers, cathodic protection features, or features that are not in service.<\/p>\n

A common approach for identifying this issue is to validate the data using a tool like ArcGIS Data Reviewer or to have a layer in your map that highlights the features using definition queries. The Gas and Pipeline Utility Network Foundation solution<\/a> has an example map called the Gas and Pipeline Data Audit<\/em> map that includes several of layers that can be used to assist in quality assurance. To audit the pressure zone subnetworks you can create a copy of the \u201cUnknown System Subnetwork\u201d layers from the Gas and Pipeline Data Audit<\/em> map and modify its definition query to verify the PressureSubnetworkName field instead of the SystemSubnetworkName.

Verify correctness<\/h3>\n

The first thing to investigate when looking at a feature that doesn\u2019t currently have a pressure zone is whether or not it should belong to a pressure zone. Remember that every in-service asset in a pipe network is pressurized and therefore should be associated to a pressure subnetwork. But … what about those assets which are not in-service?<\/p>\n

A common example of a scenario where features should not belong to a pressure system is when proposed or abandoned features haven\u2019t had their lifecycle status updated in the GIS and still appear in-service. If your company uses a job or work order polygon to track work this can make it easier to identify these situations, as this they will allow you to access the work sketches associated with the area.<\/p>\n"},{"acf_fc_layout":"content","content":"

Identify path to controller<\/h3>\n

If you\u2019ve found features in an area that don\u2019t participate in a pressure zone, but you believe they should, the first thing you need to determine is how they should be connected. In the example below we can see an area of our network that is not connected to the rest of the system.<\/p>\n"},{"acf_fc_layout":"image","image":{"ID":1740932,"id":1740932,"title":"No Pressure Zone","filename":"No-Pressure-Zone.png","filesize":18259,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/10\/No-Pressure-Zone.png","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/utility-network\/electric-gas\/gas-quality-assurance\/no-pressure-zone","alt":"","author":"304562","description":"","caption":"No Pressure Zone","name":"no-pressure-zone","status":"inherit","uploaded_to":1740872,"date":"2022-10-21 14:52:45","modified":"2022-10-21 14:52:54","menu_order":0,"mime_type":"image\/png","type":"image","subtype":"png","icon":"https:\/\/www.esri.com\/arcgis-blog\/wp-includes\/images\/media\/default.png","width":513,"height":602,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/10\/No-Pressure-Zone-213x200.png","thumbnail-width":213,"thumbnail-height":200,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/10\/No-Pressure-Zone.png","medium-width":222,"medium-height":261,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/10\/No-Pressure-Zone.png","medium_large-width":513,"medium_large-height":602,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/10\/No-Pressure-Zone.png","large-width":513,"large-height":602,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/10\/No-Pressure-Zone.png","1536x1536-width":513,"1536x1536-height":602,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/10\/No-Pressure-Zone.png","2048x2048-width":513,"2048x2048-height":602,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/10\/No-Pressure-Zone-396x465.png","card_image-width":396,"card_image-height":465,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/10\/No-Pressure-Zone.png","wide_image-width":513,"wide_image-height":602}},"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"

We expect every in-service feature in our pipeline network to participate in either the gas or cathodic protection system. The utility network was originally designed to require this; however, this constraint was relaxed due to the need of many customers to incrementally loading their data.<\/p>\n

You can use the shortest path<\/a> trace to identify the path between each system controller. You can configure the shortest path trace by using the shape length as your network attribute and by setting the condition barriers for the trace to match those of your system tier. If you are unsure what the condition barriers are for your network you can find this information in the Tier section of the Network Properties page on the utility network layer in your map.

Conclusion<\/h1>\n

Now that you\u2019ve stepped through the examples in this blog you should be familiar with the quality assurance techniques you can use to find and features that don\u2019t belong to a subnetwork, or belong to too many subnetworks, along with several approaches for correcting these issues.<\/p>\n

I hope you find these techniques useful to keep your data clean so you can get the most out of your gas and pipeline GIS data! If you\u2019ve read the previous two blogs in this series, you are now fully prepared to start creating and managing your gas and pipeline data in a utility network using subnetworks! You can find links to the other gas and pipeline blogs below and I recommend you download and start getting familiar with the Gas and Pipeline Referencing Utility Network Foundation<\/a> from the ArcGIS Solutions<\/a> team.<\/p>\n
