Network Dataset properties

Summary

The Describe function returns the following properties for Network Datasets. Dataset Properties are also supported.

A Network Dataset returns a dataType of "NetworkDataset".

A network dataset is used to model transportation networks.

Properties

Property	Explanation	Data Type
networkType (Read Only)	The type of workspace containing the network dataset. This property returns the following keywords: Geodatabase Shapefile SDC	String
supportsTurns (Read Only)	Indicates if the network dataset supports turns.	Boolean
isBuildable (Read Only)	Indicates if the network dataset can be built. SDC-based network datasets cannot be built as they are read-only.	Boolean
catalogPath (Read Only)	The path of the network dataset.	String
attributes (Read Only)	Returns a Python list of Network Attribute objects.	Object
edgeSources (Read Only)	Returns a Python list of Edge Source objects.	Object
junctionSources (Read Only)	Returns a Python list of Junction Source objects.	Object
turnSources (Read Only)	Returns a Python list of Turn Source objects.	Object
systemJunctionSource (Read Only)	Returns a System Junction Source object defined for the network dataset. This property is not available with SDC-based network datasets as they do not system junction sources.	Object
supportsDirections (Read Only)	Indicates if the network dataset supports generating directions.	Boolean
directions (Read Only)	Returns a Network Directions object defined for the network dataset. This object can be used to get directions information at the network dataset level. The directions property is available only if the supportsDirections property returns true.	Object
sources (Read Only)	Returns a Python list of Network Source objects. This property returns all the sources for the network dataset. If you want to get a list of particular source type, for example, only the edge sources, use the edgeSources property.	Object
elevationModel (Read Only)	The network elevation model used to refine the connectivity of the network dataset. This property returns the following keywords: None Elevation Fields Z Coordinate Values	String
timeZoneAttributeName (Read Only)	The name of the time zone attribute. If the network dataset does not support time zones, this property returns an empty string.	String
timeZoneTableName (Read Only)	The name of the time-zone table that stores the list of time-zones used by the network dataset.	String
supportsHistoricalTrafficData (Read Only)	Indicates if the network dataset supports the use of historical traffic information.	Boolean
historicalTrafficData (Read Only)	Returns a Historical Traffic Data object defined for the network dataset. This object can be used to get historical traffic information such as the historical traffic tables used by the network dataset. This property is availabe only if the supportsHistoricalTrafficData property returns true.	Object
