Description

This tool calculates for each grid cell of the selected grid system the area that is covered by the input polygons layer.

Parameters

	Name	Type	Identifier	Description	Constraints
Input	Polygons	shapes, input	`POLYGONS`	-	-
Input	Target System	grid, input, optional	`TARGET_TEMPLATE`	use this grid's system for output grids	-
Output	Area of Coverage	grid, output	`AREA`	-	-
Options	Method	choice	`METHOD`	Choose cell wise, if you have not many polygons. Polygon wise will show much better performance, if you have many (small) polygons.	Available Choices: [0] cell wise [1] polygon wise Default: 1
	Output	choice	`OUTPUT`	-	Available Choices: [0] area [1] percentage Default: 1
	Only Selected Polygons	boolean	`SELECTION`	-	Default: 1
	Target Grid System	choice	`TARGET_DEFINITION`	-	Available Choices: [0] user defined [1] grid or grid system Default: 0
	Cellsize	floating point number	`TARGET_USER_SIZE`	-	Minimum: 0.000000 Default: 1.000000
	West	floating point number	`TARGET_USER_XMIN`	-	Default: 0.000000
	East	floating point number	`TARGET_USER_XMAX`	-	Default: 100.000000
	South	floating point number	`TARGET_USER_YMIN`	-	Default: 0.000000
	North	floating point number	`TARGET_USER_YMAX`	-	Default: 100.000000
	Columns	integer number	`TARGET_USER_COLS`	Number of cells in East-West direction.	Minimum: 1 Default: 101
	Rows	integer number	`TARGET_USER_ROWS`	Number of cells in North-South direction.	Minimum: 1 Default: 101
	Rounding	boolean	`TARGET_USER_FLAT`	Round bounding coordinates to multiples of cell size. Ignored if cell size has decimal places.	Default: 1
	Fit	choice	`TARGET_USER_FITS`	-	Available Choices: [0] nodes [1] cells Default: 0
	Grid System	grid system	`TARGET_SYSTEM`	-	-
