Description

Calculation of accumulated cost, either isotropic or anisotropic, if direction of maximum cost is specified.

Parameters

	Name	Type	Identifier	Description	Constraints
Input	Destinations	shapes, input	`DEST_POINTS`	-	-
	Destinations	grid, input	`DEST_GRID`	-	-
	Local Cost	grid, input	`COST`	-	-
	Direction of Maximum Cost	grid, input, optional	`DIR_MAXCOST`	-	-
Output	Accumulated Cost	grid, output	`ACCUMULATED`	-	-
Output	Allocation	grid, output	`ALLOCATION`	-	-
Options	Grid System	grid system	`PARAMETERS_GRID_SYSTEM`	-	-
	Destinations	choice	`DEST_TYPE`	-	Available Choices: [0] Points [1] Grid Default: 0
	Minimum Cost	boolean	`COST_BMIN`	Zero cost works like a barrier. Use this option to define a minimum cost applied everywhere where the supplied local cost falls below this value.	Default: 1
	Threshold	floating point number	`COST_MIN`	Zero cost works like a barrier. Use this option to define a minimum cost applied everywhere where the supplied local cost falls below this value.	Minimum: 0.000000 Default: 0.010000
	Units of Direction	choice	`DIR_UNIT`	-	Available Choices: [0] radians [1] degree Default: 0
	K Factor	floating point number	`DIR_K`	effective friction = stated friction^f , where f = cos(DifAngle)^k.	Default: 2.000000
	Threshold for different route	floating point number	`THRESHOLD`	-	Minimum: 0.000000 Default: 0.000000
