Network Analysis Layer

Description

The network layer resource represents a single network layer in a network analysis service published by ArcGIS Server. It provides basic information about the network layer, such as its name, type, and network classes. Additionally, depending on the layer type, it provides different pieces of information, as detailed in the examples.

Updates at 10.4

The network layer resource now includes defaultTravelMode to identify the id of the default travel mode. Both the network layer resource and network attributes now include trafficSupport to show the level of traffic data the service supports. Attribute parameter values also have parameterType to help assist in converting parameter values to the correct type.

Updates at 10.3

The network layer resource now includes supportedTravelModes to show the travel modes configured on the network dataset used by the service.

Updates at 10.1

The network layer resource now includes hasZ and hasM properties to indicate if it is z- or m-aware.
