ArcGIS Pipeline Referencing supports three types of networks: linear referencing system (LRS) networks, LRS line networks, and LRS derived networks.
Red LRS
Una red LRS es un conjunto de rutas medidas en un método de referenciación lineal (LRM) específico.
Ejemplo
Redes de cuentakilómetros y redes de condados.
Red de línea LRS
Una red de línea LRS es una agrupación lógica de rutas a una línea en la que la medición puede aumentar o disminuir de forma monotónica. Este tipo de red admite eventos que abarcan rutas y también admite ecuaciones.
Ejemplo
Una clase de entidad de Red de estacionamiento de ingeniería contiene los campos requeridos que se van a modelar como una red de línea. 
| ID de ruta | Nombre de la ruta | Orden de línea | Id. de línea | Nombre de línea |
|---|---|---|---|---|
| {1838BE01-0BC9-4C58-9829-0F1D77717DCB} | Ruta 1 | 100 | {C043CAF0-2BF7-4598-8AC8-B382647AD490} | Línea A |
| {26710A05-C499-42C1-BB73-D3A8D402B109} | Ruta 2 | 200 | {C043CAF0-2BF7-4598-8AC8-B382647AD490} | Línea A |
| {5582FB08-84E3-49D4-8781-1D3EF7B4F2E2} | Ruta 3 | 300 | {C043CAF0-2BF7-4598-8AC8-B382647AD490} | Línea A |
Red derivada de LRS
Una red derivada es una red generada a partir de una red de línea. En una red derivada, las rutas que pertenecen a la misma línea se fusionan para crear una ruta con una medición inicial de cero.
Ejemplo
Al utilizar una clase de entidad de Red de estacionamiento de ingeniería como red principal, las rutas de red continuas se pueden derivar. Una red derivada es un conjunto de rutas donde las mediciones son continuas, un tramo de una tubería sin ramificaciones. Estas mediciones se pueden utilizar para la generación de informes de longitud y el análisis de segmentación dinámica.
Why are different types of LRS networks needed?
Pipeline Referencing supports multiple linear referencing in a single geodatabase. Business units in an organization may need to report measures in many different LRMs. For example, engineering and construction may need to collect, maintain, and report events in engineering measures (also known as engineering stations), whereas other business entities need to report measures based on the continuous length of the pipe.
Location Referencing currently does not have a limit for the number of networks that you can create in a linear referencing system (LRS). However, the type of LRS Networks you need depends on your organization’s business process. Consider the following business case:
In a pipeline organization, there are three business units that collect, manage, and maintain pipeline assets. These three business units are surveying, engineering and construction, and regulatory and compliance.
The surveying group is in charge of collecting inline inspection (ILI) data, whereas the engineering and construction group is responsible for new construction, realignments, and work order management. The regulatory and compliance group is tasked with submitting and generating reports for the Pipeline and Hazardous Materials Safety Administration (PHMSA) and other government entities.
In this case, three types of LRS networks are needed to sustain each of the three business units.
- LRS Network—ILI runs can be loaded in this type of network using the Append Events tool and will maintain continuous, uninterrupted measures for ILI data based on odometer readings.
- LRS line network—Data such as anomalies can be extracted from ILI data using the Translate Event Measures tool and transformed into an LRS line network. You can then use anomaly events to report measures based on engineering measures for the work order management or operations group.
- LRS derived network—This type of network can be used for mileage or PHMSA reporting. Note that events can't be registered to this type of network.
When are different types of LRS networks required?
Every organization's business processes are different. If your business process only requires one type of network, you do not have to configure multiple LRS Networks. For example, if your business process requires continuous measures to be maintained and reported, then you can configure your LRS to only support a non-line LRS Network. Similarly, if your business process collects and maintains data with equation points or other engineering stationing, you can configure an LRS line network to maintain the data as it is collected and an LRS derived network for continuous measure reporting. In this scenario, you can also configure events to store derived measures.
Nota:
The LRS derived network is generated from the LRS line network. If you don't configure an LRS line network, the LRS derived network can't be configured.
