Output from Find Closest Facilities

Upon successful execution, the service returns the best route and travel directions between the incident and the chosen facility and the status indicating whether the analysis was successful using the following output parameters:

output_facilities and output_closest_facilities

The provides access to the output facilities from a closest facility analysis.

The output_closest_facilities parameter includes only those facilities from the set of input facilities that were closest to at least one incident. Conversely, the output_facilities data type includes all the facilities from the analysis including the facilities that cannot be reached from any of the incidents. You can use the Status field from the output_facilities data type to determine why a facility was not used in the analysis.

The following table lists the fields that are returned for output facilities:

Field name	Description
Name	The name of the facility. The values for this field are copied from the Name field on the input facilities.
SourceID	The numeric identifier of the network dataset source feature class on which the input point is located.
SourceOID	The ObjectID of the feature in the source on which the input point is located.
PosAlong	The position along the digitized direction of the source line feature. This value is stored as a ratio. This field is null if the network location references a junction.
SideOfEdge	The side of the edge in relation to the digitized direction of the line feature. This field is limited to a domain of two values: Right Side (1) and Left Side (2).
CurbApproach	The direction a vehicle may arrive at and depart from the facility. The values for this field are copied from the CurbApproach field on the input facilities.
Status	Indicates how the facility was evaluated in the analysis. The possible values are the following: 0 (OK)—The facility was successfully located on the transportation network and analyzed. 1 (Not Located)—The facility was not included in the analysis since a traversable road was not found within the maximum search distance from the facility. 3 (Elements not traversable)—The network element that the facility is on is not traversable. This can occur when the network element is restricted by a restriction attribute. 4 (Invalid Field Values)—Field values fall outside a range or coded-value domain. For example, a negative number may exist where positive numbers are required. 5 (Not Reached)—The facility couldn't be reached due to constraints; for example, a curb approach is set so that a vehicle must travel in the wrong direction on a one-way street to reach the facility. 7 (Not located on closest)—The closest network location to the facility is not traversable because of a restriction or barrier, so the facility has been located on the closest traversable network feature instead.

The Directions Language, Directions Distance Units, and Directions Style Name parameters influence the travel directions. The parameter returns empty features if the Populate Directions parameter is False.

The following table lists the fields that are returned for output directions:

Field	Description
RouteName	The name of the route to which the driving action applies. This value is the same as the Name field of the output routes.
ArriveTime	The time of day to initiate the given driving action. If the route spans multiple days, the date and time of day are displayed.
Type	The type of maneuver that the directions feature represents or the type of the directions text. To determine whether Type refers to a maneuver type or a directions string type, check the value of the SubItemType field. Type can be used, for example, to assign an icon for direction text based on the maneuver type, or it can use a formatting style based on the directions string type when displaying the driving directions in your application. The Type value is an integer from the Maneuver Types or Directions String Types lists below.

For example, the DriveDistance is 0 for the directions text at the start of the route.

solve_succeeded

Use this parameter to determine if the analysis was successful.

output_route_data

Use this parameter to access a .zip file that contains a file geodatabase containing the inputs and outputs of the analysis in a format that can be used to share route layers with ArcGIS Online or Portal for ArcGIS. The parameter value is populated only when the Save Route Data parameter is set to True.

The file is downloaded to a temporary directory on your machine. In ArcGIS Pro, the location of the downloaded file can be determined by viewing the Output Route Data parameter value in the entry corresponding to the tool execution in the geoprocessing history of your project. In ArcMap, the location of the file can be determined by accessing the Copy Location option in the shortcut menu on the Output Route Data parameter in the entry corresponding to the tool execution in the Geoprocessing Results window.

output_result_file

Use this parameter to access the results from the analysis as a .zip file containing one or more files for each output. The format of the individual file is specified by the Output Format parameter. The parameter value is not populated when the Output Format parameter is set to Feature Set.

When a file-based output format—such as JSON File or GeoJSON File—is specified, no outputs are added to the display, since the application (such as ArcMap or ArcGIS Pro) does not draw the contents of the result file. Instead, the result file is downloaded to a temporary directory on your machine. In ArcGIS Pro, the location of the downloaded file can be determined by viewing the Output Result File parameter value in the entry corresponding to the tool execution in the geoprocessing history of your project. In ArcMap, the location of the file can be determined by accessing the Copy Location option in the shortcut menu on the Output Result File parameter in the entry corresponding to the tool execution in the Geoprocessing Results window.

output_network_analysis_layer

Use this parameter to access the network analysis layer file that stores the analysis settings and the inputs and outputs used for the analysis. The parameter value is populated only when the Save Output Network Analysis Layer parameter is set to True.

The file is downloaded to a temporary directory on your machine. In ArcGIS Pro, the location of the downloaded file can be determined by viewing the Output Network Analysis Layer parameter value in the entry corresponding to the tool execution in the geoprocessing history of your project. In ArcMap, the location of the file can be determined by accessing the Copy Location option in the shortcut menu on the Output Network Analysis Layer parameter in the entry corresponding to the tool execution in the Geoprocessing Results window.

Note:

You cannot work directly with this file even when you open the file in an ArcGIS Desktop application such as ArcMap since its data source will not be valid. The file is meant to be sent to Esri Technical Support to diagnose the quality of results returned from the tool.
