Calc Cost Allocation Map

Description

This functor identifies a region of influence for a source feature used as one of the foci points from which an accumulated cost surface is calculated. For each source feature, a region is allocated, assigning to it all cells that present the lowest costs when compared to all other source features.

Inputs

Name	Type	Description
Source	Categorical Map Type	Source feature map. Non-null value cells represent features. If null value is not defined, an error will be reported.
Cost	Map Type	Accumulated cost surface calculated from source features.

Optional Inputs

Name	Type	Description	Default Value
Use Lottery	Boolean Value Type	If true, Dinamica chooses randomly between two or more equal smallest values of cost.	True

Outputs

Name	Type	Description
Allocation	Categorical Map Type	Similar to a watershed, a map of cost regions for each source feature is created. Each region is identified by its source feature cell category. The output map has the same dimensions of the source feature map.

Notes

This calculation will report an error if a local minimum is found on the cost map.
