Description

Calculates for each polygon the area covered by each grid class.

Parameters

	Name	Type	Identifier	Description	Constraints
Input	Polygons	shapes, input	`POLYGONS`	-	-
	Classes	grid, input	`GRID`	-	-
	Look-up Table	table, input, optional	`GRID_LUT`	-	-
Output	Result	shapes, output, optional	`RESULT`	-	-
Options	Grid System	grid system	`PARAMETERS_GRID_SYSTEM`	-	-
	Processing Order	choice	`PROCESS`	If only a small part of the grid area is covered by polygons, polygon by polygon processing might give an enormous performance boost.	Available Choices: [0] cell by cell [1] polygon by polygon Default: 1
	Cell Area Intersection	choice	`METHOD`	-	Available Choices: [0] cell center [1] cell area Default: 0
	Output Measurement	choice	`OUTPUT`	-	Available Choices: [0] total area [1] percentage Default: 0
	Class Definition	choice	`GRID_VALUES`	-	Available Choices: [0] values are class identifiers [1] use look-up table Default: 0
	Value	table field	`GRID_LUT_MIN`	-	-
	Value (Maximum)	table field	`GRID_LUT_MAX`	-	-
	Name	table field	`GRID_LUT_NAM`	-	-
