ClosestFacility output data types

Describes the output data types containing the results from a closest facility analysis.

ClosestFacilities and Facilities

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

The ClosestFacilities data type includes only those facilities from the set of input facilities that were closest to at least one incident. The 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 Facilities data type to determine why a facility was not used in the analysis.

These data types support the following fields. In addition to these fields, the data types also include all the fields from the input feature class used as facilities for the analysis.

Field nameDescriptionData type

Status

Indicates the status of the point with respect to its location on the network and the outcome of the analysis. The possible values are the following:

  • 0 (OK)—The point was successfully located on the network.
  • 1 (Not Located)—The point was not successfully located on the network and consequently was not included in the analysis.
  • 2 (Network element not located)—The network element identified by the point's network location fields can't be found. This can occur when a network element where the point should be was deleted, and the network location was not recalculated.
  • 3 (Element not traversable)—The network element that the point is located on is not traversable. This can occur when the 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 exists where positive numbers are required.
