Description

License:

The ArcGIS Location Referencing license is required to use this resource.

Linear referencing services provide access to the data, metadata, and behaviors of a linear referencing system (LRS) in a geodatabase. The root linear referencing resource contains lists of the LRS related layers and LRS workspaces in your published map.

Note:

REST operations that involve network editing are only supported in services with the linear referencing and version management (branch versioning) capability enabled.
