The Distance Decay endpoint provides a percentage rating of how well you're reaching your market areas by calculating your market penetration based on either the ring or drive-time or drive-distance trade areas. Either persons or households can be used to calculate market penetration.

The analysis can be restricted to an analysis extent if the AnalysisExtent parameter is specified. Optional SingleStoreID parameter restricts the analysis to a single store of the store layer.

• The DecayAreasType parameter specifies the simple ring or drive-time decay type.

• The Radii parameter specifies the radii of areas in ascending order and the DistanceUnits parameter specifies units in which radii are measures. For simple ring decay type, ordinary Esri units are used. For drive time decay type, ordinary Esri units or extended drive time units are used.

• The BuildNonOverlapped parameter specifies creation of non-overlapped areas or overlapped areas (default).

• The CreateDetailedBorder parameter specifies creation of detailed border or not (default). It is used for drive-time decay type.

• The UseGeographyLevel parameter specifies the use of summarization variables of a geography hierarchy in calculation of market penetration. If this parameter is true, the DataHierarchy value can be specified.

• The TotalMarketCountField parameter specifies the total market count field from summarization variables of the geography hierarchy if the last one is in use or from the store layer.

• The CustomerWeightField parameter can specify a weight field in the customer layer for calculation a weight rather than number of customers, sales for example.

NOTE: Since Business Analyst Server 10.0, the DataLayerID parameter is replaced with an optional DataHierarchy parameter.

The example below generates a Distance Decay report between a list of stores and customers.
