esriNAImpedanceTransformationType Constants

Location-Allocation impedance transformation type

Constant	Value	Description
esriNAITTLinear	0	Distance between two points will be scaled linearly using a transformation parameter. (e.g. distance(i,j)=parameter*distance(i,j)
esriNAITTPower	1	Distance between two points will be scaled according to a power using a transformation parameter (e.g. distance(i,j)=distance(i,j)^parameter
esriNAITTExponential	2	Distance between two points will be scaled according to an exponent using a transformation parameter (e.g. distance(i,j)=e^(parameter*distance(i,j))

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server. Requires Network Analyst Extension.

Remarks

The values within this enumeration are used to indicate the type of impedance transformation to be applied while solving a Location-Allocation problem instance. The ImpedanceTransformation property of the INALocationAllocationSolver is used in conjunction with this transformation type.

The esriNAImpedanceTransformationType enumeration has the following values:

esriNAITTLinear - specifies that a linear decay should be applied
esriNAITTPower - specifies that a power decay should be applied
esriNAITTExponential - specifies that an exponential decay should be applied
