Performs origin-destination matrix analysis.

Remarks

NAODCostMatrixSolver is a Network Analyst solver that finds the shortest path distances between a set of origins and destinations. It can minimize the shortest path on any suitable cost attribute and write the results to an in-memory feature class, which can then be exported to a table. It has options to limit the number of destinations to compute from any origin by either specifying a maximum number of destinations to find or by specifying a cutoff value. For example, compute distances from a set of origins to, at the most, three destinations that are within 10 Km. It can also generate straight-line geometries connecting each origin-destination pair. The NAODCostMatrixSolver honors all of the settings of the INASolverSettings interface.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

getDefaultTargetDestinationCount

public Object getDefaultTargetDestinationCount()
                                        throws IOException,
                                               AutomationException

The default number of destinations to find.

Remarks

DefaultTargetDestinationCount specifies the number of destinations to find for the NAODCostMatrixSolver. For example, solving for 10 destinations will return the cost-distance to the 10 closest destinations from each origin.

DefaultTargetDestinationCount is considered “default” because it can be overridden on a feature-by-feature basis by the presence of a non-null value in the TargetDestinationCount field of an individual feature.

DefaultTargetDestinationCount, if not NULL, can be cast as an integer. It is returned as an object/variant in order to allow a NULL value to be used to specify an unlimited default destination count. A DefaultTargetDestinationCount of NULL indicates that a path will be found, if possible, between every origin and every destination.

If a specific origin feature has a non-null value in the TargetDestinationCount field of its NAClass, this value will override the DefaultTargetDestinationCount for that origin.

If an attempt is made to set the DefaultTargetDestinationCount to a non-integer value, it will be rounded to the nearest integer.

A Variant

Remarks

DefaultCutoff specifies how far to search for the destinations around each origin. For example, setting a default cutoff of 10 miles will only return those destinations within 10 miles from each origin.

DefaultCutoff is considered “default” because it can be overridden on a feature-by-feature basis by the presence of a non-null value in the Cutoff_<attribute name> field of an individual feature.

DefaultCutoff, if not NULL, can be cast as a double. It is returned as an object/variant in order to allow a NULL to be used to specify no default cutoff value. A DefaultCutoff of zero indicates a search distance of zero. A DefaultCutoff of NULL indicates an unlimited search distance.
