Propiedades del dataset de red
Resumen
La función Describir devuelve las siguientes propiedades para los Datasets de red. Las Propiedades del dataset también son compatibles.
Un dataset de red devuelve un tipo de datos de "NetworkDataset".
El dataset de red se utiliza para crear modelos de las redes de transporte.
Propiedades
Propiedad | Explicación | Tipo de datos |
networkType (Sólo lectura) |
The type of workspace containing the network dataset. This property returns the following keywords:
| String |
supportsTurns (Sólo lectura) |
Indicates if the network dataset supports turns. | Boolean |
isBuildable (Sólo lectura) |
Indicates if the network dataset can be built. SDC-based network datasets cannot be built as they are read-only. | Boolean |
catalogPath (Sólo lectura) |
The path of the network dataset. | String |
attributes (Sólo lectura) |
Returns a Python list of Network Attribute objects. | Object |
edgeSources (Sólo lectura) |
Returns a Python list of Edge Source objects. | Object |
junctionSources (Sólo lectura) |
Returns a Python list of Junction Source objects. | Object |
turnSources (Sólo lectura) |
Returns a Python list of Turn Source objects. | Object |
systemJunctionSource (Sólo lectura) |
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 (Sólo lectura) | Indicates if the network dataset supports generating directions. | Boolean |
directions (Sólo lectura) |
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 (Sólo lectura) |
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 (Sólo lectura) | The network elevation model used to refine the connectivity of the network dataset. This property returns the following keywords:
| String |
timeZoneAttributeName (Sólo lectura) | The name of the time zone attribute. If the network dataset does not support time zones, this property returns an empty string. | String |
timeZoneTableName (Sólo lectura) | The name of the time-zone table that stores the list of time-zones used by the network dataset. | String |
supportsHistoricalTrafficData (Sólo lectura) | Indicates if the network dataset supports the use of historical traffic information. | Boolean |
historicalTrafficData (Sólo lectura) | 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 |
