As I start to move towards testing the Location Referencing tab of the Ribbon in ArcGIS Pro 3.0.0, I'm noticing that if I mouse-over a button and Press F1 for more help, the page it goes to is often/invariably from ArcGIS Pipeline Referencing instead of from ArcGIS Roads and Highways and I am using the latter. Sometimes I switch a page like Extend a route—ArcGIS Pro | Documentation (which has a Pipeline Referencing URL) for one like Extend a route—ArcGIS Pro | Documentation (which has a Roads and Highways URL) by replacing "location-referencing-pipelines" in the URL with "roads-highways". Do I need to always go to the trouble of doing that or are all such pairs of pages identical?   ... View more

At 160319: Error stopping an edit session with save edits—ArcGIS Pro | Documentation help is requested from anyone encountering that error. While investigating LRS Line Networks I have stumbled across a procedure that leads to that error every time it is run a second time within an ArcGIS Pro 3.0.0 session. The code is as below and the way I am running it is as a Python Script tool with no parameters.    If the tool is run once it works.  If it is then run again it gives: arcgisscripting.ExecuteError: ERROR 160319: Error stopping an edit session with save edits Error stopping an edit session with save edits [TestLRSNetwork] Failed to execute (AppendRoutes).   #

I'm starting to have success creating and loading an LRS dataset and network into a file geodatabase using ArcGIS Pro 3.0.0, and I have included fields in my LRS Network to support Lines, thus making it into an LRS Line Network. Does the LRS Line Network unlock any particular functionality beyond that available for an LRS Network? I've reviewed Lines—ArcGIS Pro | Documentation and have come away with the impression that the advantage of including Line fields is that the Location Referencing tools (editing and geoprocessing) will keep them in sync with the Centerlines and routes in the LRS Network that are built upon them but that just happens in the background.  I'm assuming that to display them I just treat them as a normal polyline field and use line symbology based on that. I haven't looked at equations and stationing yet and gather that until I start to use events with my LRS Network they will have no role to play.   ... View more

I'm new to Roads & Highways but have used ArcInfo Workstation Dynamic Segmentation and ArcMap Linear Referencing for intermittent intensive periods, often separated by years, over many years.  This week I've been using ArcGIS Pro 2.9.3 to successfully create a route feature class in a file geodatabase from a line feature class with a Route_ID, From_meas and To_meas fields, and then to display hatches and labels along the routes at various intervals. I was then given access to a Location Referencing license and expected to start editing my routes using tools on the Location Referencing tab of the ribbon.  It was then that I came to realize that Location Referencing is much more than a new name for Linear Referencing (and Dynamic Segmentation), and that I would need to create an LRS dataset before I could even see  the Location Referencing tab of the ribbon.  I used the Create LRS geoprocessing tool from the Location Referencing Toolbox to create an empty LRS dataset, and can now see the Location Referencing tab of the ribbon.  However, I've not been able to use that to even digitize a simple test route so I'm turning my attention to whether I can use either a route feature class in a file geodatabase created from a line feature class with a Route_ID, From_meas and To_meas fields, or the line feature class itself to create an LRS dataset. Is there any documentation or help available here that could guide me through the steps to do that? I think these bits of information about my situation may be relevant: data is in a file geodatabase no need for events along the routes at this stage line feature class is in a geographic coordinate system and the from and to measures are in meters - to create a route feature class I projected them to a projected coordinate system, created the routes and then projected back. no calibration points are available no redline feature class is needed at this stage I have no prior experience of Roads & Highways in ArcMap and my data does not come from that - it is simply a line feature class with fields suitable for building routes In an attempt to work my way through where I'm stuck I developed some ArcPy code to illustrate it and posted that as Creating LRS dataset from line feature class with route IDs, from and to measures using ArcGIS Pro - Geographic Information Systems Stack Exchange.  However, that effort has so far been unsuccessful. - Graeme   ...

Is it possible to configure an experience using Experience Builder that enables its users to be able to turn off the basemap (not just switch to another basemap)? I was hoping to find an option to do this on the Layers and/or Basemap widgets but I cannot find one. The reason I was looking for this is to try and increase performance when panning the map in an experience. ... View more

The Map widget of Experience Builder currently seems to lack functionality to turn on a dynamic graticule (lat/long) and/or measured grid (easting/northing). The Functionality Matrix for Web AppBuilder and Experi... - Esri Community mentions in Functionality Matrix for ExB and WAB _March 2022.docx that the addition of "Grid Overlay" functionality has a status of TBD.  I am assuming that this is the Graticule and Measured Grid functionality that I am looking for.  It also mentions that "Gridded Reference Graphic" functionality is Planned with No timeline (as yet).  I am assuming that this is Reference Grid functionality, which is related to but not the Graticule and Measured Grid functionality that is the subject of this Idea. ...
