NetworkDatasetLayer

class arcgis.network.NetworkDatasetLayer(url, gis=None)

The network dataset layer resource represents a single network dataset layer in routing services published by ArcGIS Server. It provides basic information about the network dataset layer, such as its name, type, locate settings, travel modes, and other information as in the JSON syntax below. It also provides information about the network dataset, such as name build time, build state, network attributes and, network sources.

Note

This is only available for ArcGIS Enterprise 11.1+

locate(input_locations, travel_mode=None, locate_settings=None, barriers=None, polyline_barriers=None, polygon_barriers=None, return_barriers=False, return_polyline_barriers=False, return_polygon_barriers=False, output_source_field_names=None, out_sr=None, future=False)

When performing analysis using routing services, the inputs to an analysis rarely fall exactly on top of the edges or junctions of the network dataset the service is using. For example, you may be using a network dataset constructed from street centerline to power your routing services, and the input points you want to analyze are the centroids of parcels in your city. These parcel centroids do not fall on top of the street centerline; rather, they are offset some distance from the streets. To successfully perform a network analysis using your routing services, the routing services must identify the location on the network dataset where each analysis input lies. This network location, rather than the input’s original location, is used in the analysis. Typically, the longitude and latitude of the inputs are passed in and the routing services compute the location on the network during the solve operation. With the locate service, you can compute the locations on the network before calling the solve operation.

The locate service is performed on a network dataset layer resource. You can provide arguments to the locate service as query parameters defined in the parameters table below. The locate service can be used in scenarios such as the following:

• Reuse location fields during the solve operation - You have a set of regularly serviced customers. You can use the locate service to calculate location fields, and use the located inputs in the routing services. This helps to speed up routing services since the service doesn’t need to locate inputs again and you can reuse the locations in multiple places.

Note

The settings and barriers you use to locate inputs should match the eventual analysis settings when you perform routing service; otherwise, the routing services may still relocate because the locations are not valid for a different travel mode or with barriers.

• Compute serviceability - Before you perform a routing request, you can call locate to determine serviceability. For example, the mode of travel may only allow service inputs that are 500 meters off the streets. You can perform a locate service with 500 meters as the search tolerance and determine which inputs cannot be serviced before you perform a more advanced routing service.

• Use DistanceToNetworkInMeters to calculate service time - You can gain information from the locate service response to fine-tune your routing service settings. For example, if you want to know how far each input is off network to perform delivery analysis, and it takes time to go from the parked vehicle location to the delivery location, you can use the DistanceToNetworkInMeters field for each record in the response. Once you know how far away the actual location is from the network, you can use a speed factor to calculate a service time for each input based on its distance off the network.

• Query fields from the underlying source features -The locate service also supports returning additional field values from the source features where the inputs are located. For example, you can set different curb approaches on the inputs depending on the type of road on which they’re located. If the input is located on a major road, you can set it to right or left side of the vehicle, depending on the driving side of the country where it’s located. If the input is located on a local road, either side of curb approach will work since a vehicle can cross a local road for a delivery.

Parameter	Description
input_locations	Required FeatureSet, list of Point geometries, or a comma separated string. To see the fields that can be included in your Feature Set refer to the Locate Service doc.
travel_mode	Optional string. Travel modes provide override values that help you quickly and consistently model a vehicle or mode of transportation. The chosen travel mode must be pre-configured on the network dataset that the routing service references.
locate_settings	Optional dictionary containing additional input location settings. Use this parameter to specify settings that affect how inputs are located, such as the maximum search distance to use when locating the inputs on the network or the network sources being used for locating. To restrict locating on a portion of the source, you can specify a where clause for a source. The dictionary of parameters can be assigned to the ‘default’, or to the ‘overrides’ key which holds the dictionary of parameters for each override, types of override are ‘inputLocations’, ‘barriers’, ‘polylineBarriers’, ‘polygonBarriers’. Use the LocateSettings class to create the dictionary for each override or for the default. Note ‘default’ has to be present if you want to pass in any locate_settings to the service. In addition, locate settings for default have to be complete, meaning all properties need to be present. For each override, the keys do not have to be complete. Note for ‘polyline_barriers’ and ‘polygon_barriers’, tolerance and tolerance_units are not supported. # Usage Example: >>> from arcgis.network import LocateSettings >>> locate_settings = LocateSettings( tolerance=5000, tolerance_units=ToleranceUnits.meters, allow_auto_relocate=True, sources=[ {"name": "Routing_Streets"} ] ) >>> result = route_layer.solve( stops=stops, locate_settings={ "default": locate_settings.to_dict() } )

The Origin Destination Cost Matrix service helps you to create an origin-destination (OD) cost matrix from multiple origins to multiple destinations. An Origin Destination Cost Matrix is a table that contains the cost, such as the travel time or travel distance, from every origin to every destination. Additionally, it ranks the destinations that each origin connects to in ascending order based on the minimum cost required to travel from that origin to each destination. When generating an OD Cost Matrix, you can optionally specify the maximum number of destinations to find for each origin and the maximum time or distance to travel when searching for destinations.

The results from the Origin Destination Cost Matrix service often become input for other spatial analyses where the cost to travel on the street network is more appropriate than straight-line cost.

The travel time and/or distance for each origin-destination pair is stored in the output matrix (default) or as part of the attributes of the output lines, which can have no shapes or a straight line shape. Even though the lines are straight, they always store the travel time and/or travel distance based on the street network, not based on Euclidean distance.

LocateSettings

class arcgis.network.LocateSettings(tolerance, tolerance_units, allow_auto_relocate, sources)

Parameters available for locate settings that can be passed to the solve operation. See locateSettings for full descriptions.

Parameter	Description
tolerance	Allows you to control the maximum search distance when locating inputs. If no valid network location is found within this distance, the input features will be considered unlocated. A small search tolerance decreases the likelihood of locating on the wrong street but increases the likelihood of not finding any valid network location.
tolerance_units	Argument should be specified as one of ToleranceUnits
allow_auto_relocate	Allows you to control whether inputs with existing network location fields can be automatically relocated to ensure valid, routable location fields for the analysis.
sources	Allows you to control which network source can be used for locating. For example, you can configure the analysis to locate inputs on streets but not on sidewalks. The list of possible sources on which to locate is specific to the network dataset this service references.

# Usage Example:
>>> locate_settings = LocateSettings(
                                tolerance=5000,
                                tolerance_units=ToleranceUnits.meters,
                                allow_auto_relocate=True,
                                sources=[
                                        {"name": "Routing_Streets"}
