Calc Distance Allocation Map

Description

This functor identifies a region of influence for a source feature employed as one of the foci points from which distances are calculated. For each source feature, a region is allocated, assigning cells to their closest source feature.

Inputs

Name	Type	Description
Source	Categorical Map Type	Source feature map. Non-null value cells represent features. If null cell value is not defined, an error will be reported.

Optional Inputs

Name	Type	Description	Default Value
Use Lottery	Boolean Value Type	If there is more than one choice to reach the shortest source feature. Dinamica chooses randomly between both equal value options.	False

Outputs

Name	Type	Description
Allocation	Categorical Map Type	Map of shortest distance regions for each source feature. Each region is identified by its source feature cell category. Map has the same dimensions of the source feature map.

Notes

The distance calculated between each cell and the closest source feature is the Euclidean distance.

It is recommended that features be unit cells, because the 2D tree algorithm used in this operator is optimized for this situation.
