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	`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	`DIR_K`	effective friction = stated friction^f , where f = cos(DifAngle)^k.	Default: 2.000000
	Threshold for different route	Floating point	`THRESHOLD`	-	Minimum: 0.000000 Default: 0.000000
(*) optional
