Hi Kevin - Off the topic from the original posting but in reference to your process to programmatically derive a Statelog-based LRM, once you transition to the ArcGIS Pro release of Roads and Highways you could conceptually model your Statelog as a "derived network" from a line network where your routes are based on your Countylog. This would automate the process of maintaining two LRMs and would also allow you to support events that span multiple Countylog routes. Here are a few resources for you to look at: Line Networks Network Configuration Deriving Event Measures -amit@esri

Re: Rce Initial extent · ‎11-05-2021

Hello Eddy - I see you have reached out to technical support per Nathan's suggestion and you've definitely been connected to the right folks. I've seen the case and have a couple of suggestions in the meantime: 1) Please validate that the spatial references between your dev and test web services are exactly the same. Also validate whether any of the layers in your gist45 web services are empty. The spatial indexes on empty feature classes can impact initial web service loading extent into web maps. 2) As a general practice, we tend to advise customers to leverage portal web map authoring whenever possible for the Event Editor as there is immediate and fine grain control of the configuration experience that cannot be easily emulated with local webmap json. If you have access to the operational ArcGIS Enterprise portal hosting R&H content, can you please try to add each layer in your local webmap to a portal webmap and see if the same issue is being presented in Portal? Here's the resource doc: https://enterprise.arcgis.com/en/roads-highways/latest/event-editor/authoring-a-web-map-for-event-editor.htm You can follow the section entitled "Using a web map on Portal for ArcGIS". -amit@esri

Re: Spur route start calibration · ‎11-02-2021

Hello Colin I've been following this thread and would like to provide some additional context. I understand you have main traversals (sometimes called trunk or inventory lines) which act conceptually as a measuring stick for certain other associated routes (in your case the partially divided opposite side routes) where you wish to derive the start measure as the measure of the main line where the two routes intersect. I'm assuming you then want to impart the end measure as the start measure plus the geometric length for the associated routes' centerlines. We do have various rail and surface transportation customers who manage their calibration method in this way. I want to emphasize that Roads and Highways does support custom calibration and non-zero starting calibration for routes. However, the software does not specifically have configurable rules to apply calibration edits when the main line is edited. At time zero implementation, you absolutely could set up your LRS network with this type of custom calibration but then it would be up to the operational users to edit the calibration points of every intersecting associated route affected by any main line edit activity. In ArcGIS Pro, you could minimize the amount of downstream derivative route calibration edits you need to complete by introducing a line network model which could act more like a control section LRM. Additionally, assuming you modeled some type of flag to deterministically associate non-mainline routes to a parent route you could also programmatically apply calibration update edits to those routes in ArcGIS Pro. For details on this capability (calibration point editing) please refer to the Enterprise Location Referencing (ArcGIS Pro) API: https://developers.arcgis.com/rest/services-reference/enterprise/apply-edits.htm -amit@esri

Re: Compress Geodatabase · ‎08-30-2021

Here’s a plan to get you going. This pattern should be implemented on a very regular basis to optimize editing performance in the LRS. Identify connected users Prevent the geodatabase from accepting new connections Stop AGS services and disconnect users Validate (and clear) orphaned connections if any (check sde.process_information) Reconcile lockroot version (if applicable) and post changes to Default (If this was completed before the process then you can skip) Compress the geodatabase (Connect as SDE) Allow the geodatabase to begin accepting new connections Start AGS services Rebuild indexes on system tables (Connect as SDE, Uncheck Rebuild Delta Tables Only) Update statistics on system tables (Connect as SDE, check System Tables and check all the Analyze options) Rebuild indexes (Connect as data owner, Uncheck Rebuild Delta Tables Only) Update statistics (Connect as data owner, check all the Analyze options) In case you are interested in GDB automation, you could reference the following: http://desktop.arcgis.com/en/arcmap/latest/manage-data/geodatabases/using-python-scripting-to-batch-reconcile-and-post-versions.htm A handy tool my esri colleague wrote: https://community.esri.com/docs/DOC-9914-compress-geodatabase-tool -amit@esri Esri Transportation LRS Team

Re: Event Editor Asset ID Guid · ‎08-02-2021

What you are seeing is the expected behavior in older versions of our software. This has been changed within ArcGIS Pro and newer versions of Enterprise (Event Editor) so that the Event IDs created in Event Editor align with the format created by the Desktop software. Once the you transition to Pro for your Roads and Highways Desktop application the Event ID format will be in alignment. With respect to the usage of our Event ID field for synchronizing assets in your infrastructure asset management system, I would recommend against using it. Event IDs are not unique across time. When an event is time sliced, the same Event IDs are used for multiple records, thus, a single Event ID can refer to multiple objects in the LRS network. You can implement GDB Global IDs to provide unique asset identifiers. Global IDs are unique for each object across time, making them ideal to use as the Asset ID in this context. -Amit@esri Esri LRS Transportation Team

Hi Kevin - Yes @CliveReece is correct with respect to the field precision/scale versus LRS M tolerance settings. I would also second his suggestion to look more closely at the underlying centerline geometry causing the Calculate Route Concurrency (CRC) geoprocessing tool to return very short overlap sections. The first thing I would suggest is interrogating the geometry of those short segments by dynamically segmenting (Make Route Event Layer) the output of the CRC GP against your network. You'll likely need to zoom to scales at 1:1 are larger to see the issue. Common occurrences of this issue can be seen at shallow angle gores between main lines and ramps, digitization overshoots as well as in cases where concurrent routes were loaded but those routes did not exhibit a complete vertex-vertex match. In all cases, running the LRS Centerline De-Duplication tool causes the centerlines originally used to load routes to collapse into a single short centerline segments since they are within the XY tolerance. Once this happens, the centerline sequence table is also updated so you'll need to trace through the centerline sequence and centerlines to resolve the issues. Here are some examples (Scale: 1:1): Ramp gore point within XY tolerance: Routes loaded vertex mismatch on concurrency -If you need assistance advise contacting technical support or your Advantage Program TA and they can connect you either with an analyst or one of us. -Amit Enterprise LRS Transportation Team

Hello Elizabeth, It sounds like you've chosen to author your Event Editor webmap using a local file on the web server where the app is deployed. May I ask what version of Roads and Highways you are using? It also sounds like you have portal running so I might also ask whether there is any specific business reason to use the local webmap as opposed to simply authoring your webmaps on portal? Outside of those questions, the LRS service you are using for webmap configuration usually defaults to the zoom scale the MXD you published from was set to. You might want to check on that MXD. Additionally, do you have any feature layers in your map without a spatial extent set? Sometime empty event layers can cause this if you set the initial extent to the full map extent: You've likely already found our resource document for this topic but I'm adding it to this thread just in case. Authoring Webmaps for Event Editor Incidentally, extent (among other things) in Event Editor can also be controlled via URL parameters. https://enterprise.arcgis.com/en/portal/latest/use/use-url-parameters.htm And finally, our resource document on smart launching Event Editor through URL parameters: https://enterprise.arcgis.com/en/roads-highways/latest/event-editor/smart-launching-event-editor-through-url-parameters.htm Hope that gives you a good starting point to resolve your extent issue. -amit@esri Esri Transportation LRS Team

Hello When you create an LRS there are several domains added to the geodatabase specific to Location Referencing (dActivityType, dLRSNetworks, dReferentMethod). If you are using a database user other than the user that originally created those domains you'll need to either remove the domains or create the LRS when connected with the originating user. Our Create LRS GP tool should have notified you of this requirement: Thank you, -Amit Esri LRS Transportation Team

Assuming you have authorized your ArcGIS Enterprise 10.8.1 licensing (GIS Server) with Location Referencing Solutions and you are leveraging ArcGIS Pro to publish your LRS services then there is no separate installer for the LRS Services for ArcGIS Server. If you are planning to model event data in your enterprise LRS and wish to leverage our ArcGIS Event Editor web application for production event management then you can download the stand-alone installer from My Esri. -amit@esri Esri Transportation LRS Team

Hello Patrick Aside from Ayan's recommendation regarding the ability to view Event Behavior properties for each LRS event in the Location Referencing properties there is another trick which is closer to an "Easy Button"; for now lets call it an "Easy-ish button"... From the ArcGIS Pro Analysis tab, open a ModelBuilder session. Drag into the canvas each (or all) of the events you would like to view the event behaviors for. From ArcToolbox Location Referencing Tools-->Configuration-->LRS Event drag in the Modify Event Behavior Rules GP tool for each event you want to report on. Connect each event feature class to each GP tool: From the ModelBuilder tab, click on the Report tool Since the Event Behavior Rules are parameters of the Modify Event Behavior Rules GP tool you can filter the view to see all the rules: What's more, you can also export the report to XML and then use other tools (like MS Excel) to parse the XML into a standard report of your choosing: One of the nice things about this approach is that it also sets you up for a model to bulk update event behavior through either ModelBuilder or Python! Hope that helps - -amit@esri Esri Transportation LRS Team

Hello Aaron - Can you validate that the dLrsNetworks domain has the correct network coded values representing your multiple LRMs. Can you validate that you do not in fact have RouteIds with hyphens in both networks. Is the hyphen in your Route Id part of a multi-field Route Id configuration? Lastly, can you please right click on the Blob and show the XML data. -amit@esri Esri Transportation LRS Team

Hello Ana - May I suggest having a look at the Location Referencing Tools Calculate Route Concurrencies GP. This tool will output the concurrent sections and measures for concurrent routes. As an example: Route 1 and Route 2 are concurrent but their measures increase in opposite directions. The output of CRC indicates this by flipping the From and To Measures. However, Route 3 and Route 4 run the same direction for their concurrency and so the measures are the same. I believe in your question you are looking for the concurrencies like what I've highlighted in the image. Once you've identified those sections, I suggest running Make Route Event Layer GP from the Linear Referencing tools to visualize the exact positions of these concurrent sections so you can then use the Roads and Highways Reverse Route tool to "flip" one of your concurrent routes. Hope that gives you some initial "direction" to your issue 🙂 -amit@esri Esri LRS Transportation Team

Hi Colin - for the purposes of characterizing new point or line events using referent offset location methods the referent point feature layer must be in the same map service as route/network layer. -amit

Hi Colin - Whether you use default or a surrogate for your Conflict Prevention Lockroot version the choice is mainly based on your geodatabase operational governance model. This topic is discussed here: Enabling conflict prevention in the LRS—ArcMap | Documentation I will mention that once an organization is ready to make the transition to Roads and Highways for ArcGIS Pro the geodatabase versioning strategy become less ambiguous. Roads and Highways Pro relies on a completely service oriented editing paradigm and will require the enterprise geodatabase to leverage Branch versioning. Branch versioning has a simplified version hierarchy allowing only one level of named versions to be created from the default version. Therefore, if Conflict Prevention is enabled the Lockroot version must be default. You can read more information regarding how to prepare your data for editing in Roads and Highways Pro by reviewing this resource document: Share as web layers—ArcGIS Pro | Documentation Keep up the good work! -amit@esri Esri LRS Transportation Team
