Hi Community!
We are trying to append routes to a LRS in ArcGIS Pro (3.2) by using the Append Routes Geoprocessing tool. Prior to appending, we have a set of centerlines with known routeids, but this is a many to 1 relation between centerlines and routes. In other words, each route contains at least 1, but often multiple centerlines.
If we append the centerlines directly to the centerline feature class within the LRS container, we are able to use 'Create Route' process (Location Referencing tab -> Routes group). Here it is possible to select one or more centerlines and define a RouteName.
The result of this process is a LRS Network Feature Class with 1 new route, a Centerline Sequence tabel with 56 new rows with 56 unique centerlineIds referring to the same RouteId.
But since we have to add routes for country level areas - we are talking about over 100.000 routes - we would like to create routes in an automated way. I know it is possible to use the Append Routes tool, but this tool expects unique RouteId values. This means that we have to dissolve the centerlines on the routeId field before appending the routes, but this adds a new centerline for each route instead of reusing the individual centerlines from the centerline feature class.
Are we missing something here, or is it simply not possible with the current tools to add routes with multiple centerlines in an automated way (with the standard tools from the location referencing toolbox)?
